The Big Bang Theory is the biggest lie in the western world

Not open for further replies.
Tifft's ideas should be discussed in the separate thread. They are just troll bait here.
 
You have yet to state one.


Still a misunderstanding of science.


Still true. Except no one but you talks about "knowing". It is unscientific.

Our physical models of the world simply predict. The ones we have (the Standard Model) predict nature extremely accurately. That means we keep them.

Make no mistake. GR and QM are two of the most tested theories in the history of civilization.
Every single experiment has born out the predictiveness of our models with exquisite accuracy.

They don't tell us what reality is; they merely tell us how it behaves.


This is what we have been saying all along.

If you have a need to "know" what reality and nature is, you are barking up the wrong discipline. You're seeking religion.

You make some very good posts here about the nature of science. Gravage clearly does not understand what science is and what it seeks to do.

This exchange strikes me as an excellent example of why some understanding of the philosophy of science is so important when dealing with lay people. Paddoboy (now departed) used to ridicule philosophy as useless, copying the mouthy assertions of Krauss and those like him. But Paddo, God bless him, had no science training: he was just like a faithful dog trying to be loyal to his master.

This confusion about proof - or rather lack of it - in scientific theories is a very common error, as is the notion that science explains the nature of reality, rather than simply modelling how it behaves. I suspect that the mathematical nature of a lot of physical science leads some people to think science must involve proof.

I remain eternally grateful to my 6th Form chemistry teacher, who never told a pupil he had got something "right". He always used to say "Yes, this is one model". We used to ridicule this at first, but as we encountered more of the rival models that abound in chemistry and became aware of their strengths and weaknesses, we began to see the light.

Many people do not realise that in science we often use approximate models and that we select different models of the same thing for different purposes, depending on what we are trying to predict or account for. So much for explaining reality.....:biggrin:
 
I don't know what the biggest lie in the western world is.

But I think it is safe to say this is the biggest lie on this thread!
I have also 15 years ago discovered super-conduction at room temperature up to 400 C (670 K). This lead me to the actual mechanism that causes super-conduction which is NOT caused by pair-formation of electrons.
 
And you explained wrong.

Again, this phrase "really" proven is naive.

You are arguing against stance that no rational scientist holds. You have invented a straw man.


But back to your wisdom:

That's impossible of course.

Since atomic bombs can only be invented with an intimate knowledge of protons, neutrons and atomic fission, and scientists can know nothing about these things since they're smaller than the human eye can detect, it is impossible for them to have been invented. Congratulations, you have reinvented history.

(Here's a hint: they were not invented by trial and error of simply building bigger and bigger incendiary bombs, until magically one went atomic. Atomic bombs cannot have been invented without first having a model of what atomic nuclei are made of. A predictive model. Made of math, based on observation.)

Let's end this once and for all:
Saying that atomic bombs would never be built without the model is one of the biggest lies ever, here is why:
In 1895, Wilhelm Roentgen discovered the existence of X-rays, though the mechanism behind their production was not yet understood. In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power. He demonstrated that this radiation, unlike phosphorescence, did not depend on an external source of energy but seemed to arise spontaneously from uranium itself. Influenced by these two important discoveries, Marie decided to look into uranium rays as a possible field of research for a thesis.

She used an innovative technique to investigate samples. Fifteen years earlier, her husband and his brother had developed a version of the electrometer, a sensitive device for measuring electric charge. Using Pierre's electrometer, she discovered that uranium rays caused the air around a sample to conduct electricity. Using this technique, her first result was the finding that the activity of the uranium compounds depended only on the quantity of uranium present. She hypothesized that the radiation was not the outcome of some interaction of molecules but must come from the atom itself. This hypothesis was an important step in disproving the ancient assumption that atoms were indivisible.

Curie's systematic studies included two uranium minerals, pitchblende and torbernite (also known as chalcolite). Her electrometer showed that pitchblende was four times as active as uranium itself, and chalcolite twice as active. She concluded that, if her earlier results relating the quantity of uranium to its activity were correct, then these two minerals must contain small quantities of another substance that was far more active than uranium. She began a systematic search for additional substances that emit radiation, and by 1898 she discovered that the element thorium was also radioactive.

Here is where science stops being science in the first place-it's not scientific to assume that atom exists in the first place; now, Marie Curie did prove that radiation comes from uranium compunds, and not from an outside external source, science stops being science when Marie Curie simply said that radiation comes from the atom itself-although there is not a shred of evidence actually exists.

Also, this proves why models are useless when they are dealing with things you can never prove, the only conclusions that you can make are from experiments-in experiments, like the one with Curie there is simply no place for models that cannot be tested and cannot be proven.

When it comes to radiation it's all about energy levels and its directly observable effects on the environment and on human bodies-so, the part that is untestable is that what models claim with particles and similar, but however what is truly testable and provable and proven are direct observational effects of these energy levels-so with every energy level there is a different name for it.

Atomic bombs and H-bombs and all other experiments suffer from these same misinterpretations-instead that you interpret what happened in the experiments and what you have directly observed in experiments, you interpret what mathematical models say-this is number one error.

The only thing that was really/truly proven in creating these bombs are observable effects everything that was tested in the laboratories and on the field when those bombs exploded-and not the models themselves.
 
Gravage,

DaveC426913 is right. You seem fixated on the idea that things in nature can have "proof", and that it's the job of science to "prove" things. That's not what science does. Science's job is to model the natural world so that we can make accurate predictions about how things will behave under different conditions. To do that, scientists create imaginary mental pictures of all kinds of weird stuff. In physics, we have fields and particles and waves, not to mention more mathematical things like metrics and symmetry groups and differential equations of motion.

I already answered this-if that's science, than you are not better than religion. You should stick on what exactly you can make conclusions for, not on what models say and "prove" it is, because there is no such thing that is shown in any experiment-basically you are explaning things with concepts that do not exist and cannot be proven and cannot be directly observe so that you can make any reliable conclusions..

What comes out of those mental images and the maths that fleshes them out, are predictions: if we do this in the "real world", then that will happen. If we observe this in the real world now, then tomorrow we expect to see that.

That's the biggest error ever: what will happen in the real world, it's up to experiments and their analyses, not up to the models, you should not use models to explain anything that experiments do not show and prove-directly observable:
Instead that you interpret what happened exactly in the experiments and what you have directly observed in experiments, you interpret what mathematical models say-this is number one error.
You should all abandon models and their "evidences" that you cannot directly observe with experiments in the first place.


In terms of science's ability to make predictions, it doesn't matter at all what kind of mental picture we use, as long as the predictions are accurate. Science doesn't care whether electrons actually exist in the "real world", or whether spacetime really curves.

And that is your biggest mistake, you should, because models are simply wrong, if you cannot prove the existence of the most fundamental concepts that models "predicts" that should exist-you finally have proven, that you are not doing science, you are doing pseudo-science, and you have nor right in judging people who believe in existence of Gods, ghosts, afterlives, UFOs and everything similar-because you are doing the same thing, by not doing a real science.
I will explain below why models do not predict anything, only experiments and what is directly observed in experiments predicts the world accurately.
I alread ypsoted and proved that space does not curve, what curves is the distence and trajctories of matter and energy, cosmic objects when it is inside gravitational field-outside of gravitational field nothing happens at all; everything that is made of matter and energy curves, but not space itself-this is what all experiments and proved.

What it cares about is that if the electron model tells us we can wire a battery to a light bulb then the light will go on reliably, based on our design using that electron model. Or, if we point our telescope towards galaxy A, and galaxies B and C are in particular positions in between us and A, then we will see 3 images of galaxy A, as described by our model of curved spacetime. The success or failure of the model depends only on whether our "real world" observations match what the model predicts.

This is the same example I wanted to post it, but you beat me to it: what eactly do you prove with light bulb-the way light bulb is built is not because of some model predicted, it is because trials and errors in experiments that have been done enabled to Edison how to finally create light bulb, it's wasn't because some mathematical model from quantum mechanics or any other hypothesis enabled us to do this, it was merely because of trials and errors in experiments, however the more experiments you make the less you make mistakes and you are closer in creating your new technologies-in this case light bulbs.

In 1895, Wilhelm Roentgen discovered the existence of X-rays, though the mechanism behind their production was not yet understood. In 1896, Henri Becquerel discovered that uranium salts emitted rays that resembled X-rays in their penetrating power. He demonstrated that this radiation, unlike phosphorescence, did not depend on an external source of energy but seemed to arise spontaneously from uranium itself. Influenced by these two important discoveries, Marie decided to look into uranium rays as a possible field of research for a thesis.

Also, this proves why models are useless when they are dealing with things you can never prove, the only conclusions that you can make are from experiments-in experiments, like the one with Curie there is simply no place for models that cannot be tested and cannot be proven.
End of part 1....
 
Part 2....

If we connect up that battery and the light doesn't go on as expected (and we have done everything right according to what the model requires) then the model is faulty and must be replaced by something that works.

Again, it doesn't have anything with the model, but it has everything with what experiments show, prove and indicate-based on exactly what you can directly observe.

Now, if you don't like the idea of electrons, or curved spacetime, then you're quite free to invent your own, different models to explain why that light bulb circuit works and why you see 3 images of galaxy A. For example, your model might say that little invisible pixies carry invisible parcels of darkness away from the bulb and hide them away in the battery, and that's why the bulb lights up. Your pixie model is just fine, as far as science is concerned, as long as it explains all the different kinds of electrical circuits at least as well as the electron model does.

It doesn't have anything to what I like-it is about to deal with facts and what can be directly observed in experiments-that's the bottom line.
In light bulb you can only test what you can directly observe and based on these 2 most important criterions you can create hypotheses, and it is exactly on what models should be created, not on some non-existent things that we will never be able to know and directly observe if they exist or not.

Science will never prove that electrons exist. But we can say with high confidence that, as far as we can tell from "real world" observations of many different kinds, the "real world" behaves as if those imaginary electrons exist as described by the electron model. And that's all that science requires in order for us to find the electron model useful.

Now, you cannot know anything, if you have not study electron itself and its physical and chemical properties, and that is 100% impossible if you cannot directly observe it-so you can prove it that it truly exists-you shoudl rather focus on what you can directly observe and based on what you can directly observe in experiments, after you do that, you should create models based on behaviours of existent and experimentally proven direct observations.
The models that you create simply cannot be proven, and their behaviours cannot be proven, because there is no way you can directly observe what their behaviours are-it's a total guess-unprovable and untestable guess!

It can't be "simply wrong", because it all predicts "real world" results that we can directly observe.

You might be able to show some other model(s) are more powerful than the ones we currently use, but you can't deny that our current models are incredibly useful and productive.

No, I already explained above, models that you create do not predict anything, only what is observed in experiments can be predicted and not what is created by models that are even untestable and unprovable-you can predict with only something that you can directly observe its behaviour in experiments-and in your models that is simply impossible, because your models go faaar beyond on what is possible to test the predictions, since they are alll untestable.

If we can never see reality the way it is, then the best we can do is to make models to the extent of our abilities.

Yes, but without models that are untestable, only use the models that are based on direct observations of whatever happens and how it behaves in experiments, not based on what your models do.

Those two statements are incompatible with one another. If our "incredible technologies" are created using the very models ("hypotheses") that you claim are "simply useless", then what's going on? Are we just having an incredible streak of blind luck? Or what?

No, it's not jst take microscope for example, all people need is to be able to magnify their vision-microscopes in a way do such things.
However the models that you call "predictive" are 100% untestable because there is absolutely nothing in technologies that can be used to directly observe them.


But the math we use does help us to make accurate predictions using our models, and we constantly check those predictions against what we directly observe. If the predictions weren't accurate, then we'd have to throw away the maths and start again.

You only prove that mathematics is religion not science, everything you do all the models that you create should be based on direct observations on what is happening in experiments-only based on this you can create accurate models and more accurate predictions.
Models that you do do not predict anything, they are predictiong of so many particles and who know what else, but when it comes to experiments, the existence of particles is wrong, because it is not shown in experiments and cannot be tested in any way; it is what you directly observe in experiments, models can indicate or prove (directly or indirectly) to exist, not what your models that are untestable.

To emphasise: science does not say that a statement like "this track in the bubble chamber was caused by an electron" is "proven". What it says is "this track in the bubble chamber is consistent with what the model of an electron passing through the chamber would predict". The difference is a bit subtle, but I hope you're starting to understand by now.


Tell me what you think a track in bubble chamber "actually proves".

How do you propose to explain and predict tracks in a bubble chamber without using some kind of model?

This is one of the examples where you should abandon all similar models such as this one, because if you create models like this you create models of something that does not exist-yes, something is passing, but you can have no idea what it is-and than saying that electron passes just because it should be electron is a logical fallacy, since maybe it's not even an particle-the problem is you will never know-never-you should create a model based on what exactly you can directly observe, you cannot observe electron, so you simply say it's an signal, but a signal from what, sure it's energy, but energy from what, that you cannot know, and that's why saying it's an electron is like making things up that are not even there-these kinds of models are wrong.

The only thing you can do is to repeat cloud chamber experiments million times (trials and errors) and than make conclusions on what exactly does this cloud chamber phenomenons do and prove or at least indicate-this is how true and correct/right models are made-after you make experiments like these million times in a row to make some sound and reasonable conclusions based on evidences that you have directly observed in cloud chambers, not by just saying that is it electron without a shred of evidence to back it up-the same as you claim fro conspiracy theorists that you claim that have no evidences-but in this case neither you have any evidence that this is electron or alpha particle or whatever-pure, untestable and unprovable speculations and assumptions.

The particle model is convenient since it allows us to make useful predictions about what will happen when we use a bubble chamber. And what happens in a bubble chamber is relevant to our understanding of physical phenomena of much wider applicability. This is why money and time are spent on bubble chambers* - they aren't there merely to keep some physicists amused.

As for scientists misguiding people, what do you want to replace (mathematical) scientific models with, exactly? What are you going to tell "people all over the world" about what goes on in a bubble chamber?


But you're wrong, again.

Mathematical models are "provable" insofar as they either make accurate predictions of real-world observations, or they do not. Not all models are created equal. There are good models and bad ones.

Again: what do you propose to replace mathematical models with? How will you make predictions about anything?

---
* Bubble chambers are outdated technology these days, since we have better ways to detect particles in collisions, so not much money is spent on them these days. At one time, though, they were the best available tool for the job.

Nothing what you claim is provable and testable if your 5 sneses cannot directly observe it, it's provable and testable only inside your heads and in your mathematics and statistics-so what?

You should make/create models only after you make tons of experiments and make conclusions of what you just directly observed, not before you make tons of experiments-because your models are wrong, and if you go any deeper in models that are untestable, than your models are useless, only models created only after you make tons of experiments and make conclusions of what you just directly observed-are correctly predictive.

Models that you use and go deeper, did not prove anything, only direct observations in experiments did-and these are the facts.
 
Part 3....

(continued...)


Ophiolite has already asked you on numerous occasions what you regard as "true science". Now I'll ask you the same thing. What does "true science" look like to you, Gravage? Can you give me an example or two of "true science"?

On your other point here, why do you think these models so good for making technologies, if they are all "simply wrong"? Just dumb luck?

I explained in my previous post.

You might say that we can start with a bad mathematical model and then when it doesn't work we replace it with a better version, by trial and error. But that's not trial and error at all, is it? That's science.

Are you stupid or what if you make thousands of experiments to prove something or to make something useful for every day lives-than it's sure trial and error-and that's all science is about.

We use the model to make a prediction. We test the prediction against the "real world" and find that it's wrong. So, we alter the model and try again. Over time, the model gets more and more accurate in making predictions. But it didn't happen by "trial and error" in the sense that we randomly changed the model each time. We tried to understand exactly which parts of the model were problematic after each test, and we just altered those parts, leaving the "working" parts alone. This is incremental, guided, deliberate improvement, not mere "trial and error".

I already explained in previous post about the models, read the answer. If you need to change the model-than it's trial and error, and this is omnipresent at all times in science and technology-if models were correct, than you will instantly create technologies and prove that they work in every day lives and you would not need anymore experiments to change models from time to time-again tiral and error.


Wrong again, if by "opinions" you mean mere untested fantasies. Because the models science uses have been tested and improved over centuries, using "real world" observations and experiments.

Models that are made exactly by what experiments show, prove or indicate and behave are based on what is truly tested, and you cannot know if particles or anything else on quantum level are based on models that are simply impossible to experiment with and they are untestable if you actually want to show and prove that they exist in the first place.

The models have been "proven" to work, in that they are demonstrably useful in making predictions and creating technologies. That is quite different from saying that the entities the models posit - like electrons or curved spacetime - have been "proven" to be real. But you seem to me mixing up those two very different kinds of "proof".

What you again fail to see is the fact that you can only use for technologies only after what you have observe in experiments-however, the problem becomes is how you interpret what has your experiment proved.
If something works in experiments, than it would work in using the same thing in every day technologies, regardless of what is your interpretations of done experiments-right or wrong.

The thing is, if you don't like the big bang theory, you're very welcome to propose an alternative hypothesis of your own. All it needs to do is to make predictions about what we will observe in the "real world" that are at least as accurate as the predictions made by the big bang theory. We don't care if your theory has invisible pixies or a purple dragon called Shiela creating the stars and galaxies, provided that it explains all the relevant "real world" observations - the relative abundances of hydrogen and helium in the universe, the Hubble law, the cosmic microwave background radiation and on on.

You say you know that something cannot come from nothing. But how do you know that? Aren't you relying on your own model to claim you know that?

I already explained to you in previous posts-big bang hypothesis is religion based on untestable models with mathematical "pseudo-evidences" of concepts that do not even exist or are even proven in experiments to exist in the first place-and they are also all untestable, for those who are are even observable, they are misinterpreted, like space thing and time which does not even exist.

From what you have written, it seem that the further those "real world" evidences are removed from what your human senses can "directly" detect, the more you distrust them.

No, I'm talking about the fact that with 5 senses there is not much you can actually prove or test in the first place, this is where technology steps in, but even technology still depends on our 5 senses, and technology itself does have upper limits.

Thus, you probably accept what you see with your naked eyes. If you look through some reading glasses, probably you also accept what you see? But what about a microscope? Do you accept that bacteria exist, for example? (Have you ever looked through a microscope and seen such things?) And if you accept what you see through a light microscope, what about an electron microscope?

I already said that bacteria exist-just take microscopes and you can magnify it, you read nothing, you should stop posting anything to me if you haven't read anything before in my previous posts-typical, you listen only to yourself.
Electron microscope, I alread posted before, you make me angry by not reading my posts-DON'T WRITE TO ME IF YOU DON'T READ MY ANSWERS TO OTHERS, NOT JUST TO YOU.

Even if you somehow one day manage to directly observe particles and "prove" their existence, read this:
An ultrasound picture of a baby accurately reflects the actual form of the baby. A Scanning Tunneling Electron Microscope does not accurately reflect the form of an atom because it simply uses an artificial dot to represent the presence or absence of an atom. In short, the "map" that STM's give us is abstracted from reality and does not accurately portray an atom (in large part because STM's still simply due not measure at the scale of an atom).

There's a philosophy idea that in order to say we can "see" something, we have to be able to collect consistent information by several different methods. For example if all we have is a STM, then we don't know which parts of the image are artifacts and which are real so we haven't seen anything. But if we have an STM and crystallography, we can have more faith in the features that are common to both images - such as interatomic distances and the geometry of crystal structure. But we still couldn't say that we've seen the shape of an atom since that would look different in each instrument's image.

A great example is people who "discovered" lost cities under the sea. They saw regular patterns of lines on the seafloor in Google Earth and interpreted them as ancient roads or walls. But they were only seeing artifacts from ships that had sailed back and forth in straight lines collecting data. If they had looked both at those sonar scans and some other data for the same location, they would have only seen the lines on one image and been able to conclude that they were either an artifact of the sonar or below the level of sensitivity of the other instrument.
 
Part 4....

It seems to me that you pick and choose what you think counts as "real world" evidences based on how far you think you can trust a scientific instrument and the people who made it. And that probably depends on how much you think you understand about how it works. So, if the workings of an electron microscope are a mystery to you, then the electron microscope becomes, for you, a source of "unproven" facts about other stuff that can't be "proven".

Again the way how exactly is electron microscope made does not prove a single thing about something you can never test-you simply can never know what is behind surface.
http://science.howstuffworks.com/scanning-electron-microscope2.htm

The parts are real, but the explanations are untestable when they speak about atoms and all other particles and everything else on atomic and subatomic levels.

At the other end of the scale, you probably trust a pair of binoculars well enough. A light telescopes? Maybe, but not so much. Radio telescopes? Forget it - you don't understand how radio works too good, so anything a radio telescope shows is probably "unproven" fantasy. And gravity wave detectors? No idea how those might begin to work, so now we're in the realm of "mathematical pseudo-evidences".

I'm right, aren't I?

No, you are not right at all, you are actually 100% wrong; we use radiowaves every single day-it's all about on how much we use every single day to listen our radio-stations and all kinds of sounds, so we can actually and we do observe their effects on environment and we listen to the radios-what effects gravity waves have nothing-absolutely nothing-with gravity waves we know absoltely nothing, because like I said it can be from anything, literally anything, plus, what I bet is that gravity waves are not really detected, it's shock waves that are detected in the first place.
That's why those so called-gravity waves are not detected, maybe radiowaves are detected-again with such a distance of 1.3 billion light years away you cannot know anything what signal have you detected and from what exactly-that was my point with gravity waves, while it is 100% certain of what we use radiowaves every single day-plus there is how much energy they hav also:

The difference between ionizing radiation and non-ionizing radiation is exactly here: in energy levels-so basically these are all the same waves, their key differences exist in energy levels:
https://en.wikipedia.org/wiki/File:EM-spectrum.svg

What you fail to understand is that scientists have detected those energies, but the problem with radiowaves, microwaves and similar was not at all in proving it that they exist, the problem was in how to divide them based on energy levels that they are detected with measurable devices and directly observale effects that they have on environment and on human bodies and how they can be used in every day lives.

I don't see you suggesting any way we can see more of the "real truth" you keep banging on about.

If the limits on what can be proven have already been reached, should we just stop doing science completely, then? Is this what you think?

Yes, if you cannot create testable models-again no untestable and unprovable concepts involved like particles, quantum mechanics and similar, only what experiments show, prove and indicate and what you can conclude frm the experiments, not from something that you cannot actually test-like particles, quantum mechanics, and similar.

Are you saying we should just stop trying to find out more about the world from now on, and be content with where our current "unproven" science has got us to?

And this is the biggest fallacy ever, the biggest lie ever-you cannot find more about the world, if you cannot directly observe anything at all, if your models of particles and all other abstract concepts that are untestable in all experiments, than you cannot actually find out about the world anything concrete and for real, than it's the upper limit of science, you use those untestable models to fill the gaps and holes that you cannot test, but the fact is, it is over, true science is over long ago.

Final point: you say that mathematical models are all 100% wrong and that all physical theories are useless. But you also claim that such things are "usable for implementations for every day lives". Why, in your opinion, should we use something in our daily lives that is 100% wrong and useless?

I already answered to you this in my preious post/answer to you.
Also, if models were actually correct-there would not be any more experiments to conduct in the first place, the very fact you need all those experiments and than create models, not only something that is untestable like particles, quantum mechanics and similar; but to create models based on all of experiments what you directly observe in experiments and that's how you create new technologies for every day lives-trial and error.
The problem with matheamatical models that you insist are correct is not something any experiment can test and prove-and therefore such models should be abandoned forever.
 
One more thing, Gravage...

Can we consider a real-world example I put to you earlier?

Let's say I come to you and ask you to build me an x-ray machine by "trial and error"?

Please give me a brief outline of how you would go about doing that. Relevant questions:

1. What would you do first?
2. How would you decide what raw materials you would need, and where would you get them?
3. Suppose the eventual aim is to make an x-ray photograph of your hand, showing the bones inside. Do you think that such a "real world" picture is possible, without cutting your hand open and looking at the bones directly?
4. Can you describe to me what possible "real world" mechanism could make an x-ray photo of your hand? Note that you shouldn't rely on any "unproven" model entities, only directly-observable ones, since we can't trust any "mathematical" models.
5. Do you believe in "x-rays"? If so, why? Because they are unobservable, are they not? And if you don't believe in them, how to you think actual x-ray photos are made? Isn't the idea of "x-rays" a 100% wrong mathematical model?
6. Would your x-ray machine need to be powered somehow? What would you use to power it? How would you construct teh power supply, without depending some kind of 100% wrong mathematical model?
7. How would your machine produce the "x-rays" (if you think x-rays exist)? Or, if x-rays don't exist, how would your machine take the "x-ray" photograph of your hand?

That's enough for starters.

I'm not some weirdo, who think nothing exist, I'm simply saying that models that you create are not based on experiments, but on your mathematical equations, but they are unprovable and untestable in experiments, since you can never directly observe anything at all.

On November 8, 1895, at the University of Wurzburg, Roentgen was working in the lab when he noticed a strange fluorescence coming from a nearby table. Upon further observation he found that it originated from a partially evacuated Hittof-Crookes tube, covered in opaque black paper which he was using to study cathode rays. He concluded that the fluorescence, which penetrated the opaque black paper, must have been caused by rays. This phenomenon was later coined x-rays and though the phenomenon of x-rays is not the same as radioactivity, Roentgen opened the door for radioactive discovery.

Henri Becquerel learned of Roentgen's discovery of x-rays through the fluorescence that some materials produce. Using a method similar to that of Roentgen, Becquerel surrounded several photographic plates with black paper and florescent salts. With the intention of further advancing the study of x-rays, Becquerel intended to place the concealed photographic paper in the sunlight and observe what transpired. Unfortunately, he had to delay his experiment because the skies over Paris were overcast. He placed the wrapped plates into a dark desk drawer. After a few days Becquerel returned to his experiment unwrapping the photographic paper and developing it, expecting only a light imprint from the salts. Instead, the salts left very distinct outlines in the photographic paper suggesting that the salts, regardless of lacking an energy source, continually fluoresced. What Becquerel had discovered was radioactivity.

Though it was Henri Becquerel that discovered radioactivity, it was Marie Curie who coined the term. Using a device invented by her husband and his brother, that measured extremely low electrical currents, Curie was able to note that uranium electrified the air around it. Further investigation showed that the activity of uranium compounds depended upon the amount of uranium present and that radioactivity was not a result of the interactions between molecules, but rather came from the atom itself. Using Pitchblende and chalcolite Curie found that Thorium was radioactive as well. She later discovered two new radioactive elements: Radium and Polonium which took her several years since these elements are difficult to extract and extremely rare. Unfortunately, the Curies died young. Pierre Curie was killed in a street accident and Marie died of aplastic anemia, almost certainly a result of radiation exposure.

In 1909 at the University of Manchester, Rutherford was bombarding a piece of gold foil with Alpha particles. Rutherford noted that although most of the particles went straight through the foil, one in every eight thousand was deflected back. "It was as if you fired a fifteen inch naval shell at a piece of tissue paper and the shell came right back and hit you," Rutherford said. He concluded that though an atom consists of mostly empty space, most of its mass is concentrated in a very small positively charged region known as the nucleus, while electrons buzz around on the outside.

The problem with alpha particles is that they are unprovable and untestable-what you can directly observe is exactly what is observed-through the foil-these what were deflected back does not mean he has proven that atom exists in the first place, it doesn't prove anything at all.
There is not a single shred of existence of alpha particle; what we do know and has been detected/observed is that radiation is real based on measuring devices, that were built just to be able to detect energies.

The part that is scientific because you can directly observe effects of x-rays or any other radiation-what you fail to understand is when you use model of atom to explain such things-the only thing that is truly proven is that radiation in Curie's case came from uranium-but she said it was from the atom inside uranium material-that is not scientific to say that it came from an atom-since there is no way you can first directly observe and prove that atom exists, and that is only possible when you can directly observe atom and test its physicla and chemical properties or whatever properties atom possesses-that is my point, and you are all too stupid to understand, you keep posting without even realizing that the approach you are using is 100% wrong, because you worship your models before experiments-which is 100% wrong.
 
You make some very good posts here about the nature of science. Gravage clearly does not understand what science is and what it seeks to do.

This exchange strikes me as an excellent example of why some understanding of the philosophy of science is so important when dealing with lay people. Paddoboy (now departed) used to ridicule philosophy as useless, copying the mouthy assertions of Krauss and those like him. But Paddo, God bless him, had no science training: he was just like a faithful dog trying to be loyal to his master.

This confusion about proof - or rather lack of it - in scientific theories is a very common error, as is the notion that science explains the nature of reality, rather than simply modelling how it behaves. I suspect that the mathematical nature of a lot of physical science leads some people to think science must involve proof.

I remain eternally grateful to my 6th Form chemistry teacher, who never told a pupil he had got something "right". He always used to say "Yes, this is one model". We used to ridicule this at first, but as we encountered more of the rival models that abound in chemistry and became aware of their strengths and weaknesses, we began to see the light.

Many people do not realise that in science we often use approximate models and that we select different models of the same thing for different purposes, depending on what we are trying to predict or account for. So much for explaining reality.....:biggrin:

But you cannot model something you cannot prove to exist! You cannot model something that you cannot test it in the first place-that's my point, it's totally wrong to model anything, if you don't have real evidences and real facts that back you up in the first place, not some abstract models with concepts that are untestable and that do not exist in the first place-that is simply not scientific, why you are calling yourselves scientists in the first place than, because you are not scientists, you belivers in mathematical models-that's religion and not science-again I'm talking about strictly physics.
 
I really don't follow your logic

I agree with you about not seeing the nutrenos making tracks in cloud chambers

No one has ever seen them

No one has ever seen the TV signal traveling between the studio and my TV set

But you have ears, you can hear it, just turn on the radio sir.
Maybe also those waves are invisible but they physical effects on environment, that's how we know gravity exists, but when it comes to quantum mechanics you don't observe anything, and even if you observe something you cannot know from what it is, with radio waves we have over 50 years of experience enough to tell it's from radiowaves, besides you have images in radiowaves, it's all about energy levels.

The signal is known to be there because the the studio is certain they are sending and I can see I am receiving, I have the picture

You said it's technology. OK it's technology

And all the technology which goes into all of the technical items present started out with ideas and trial and error

The errors become less and less as the results of previous trials become better understood

There is a concept of baby steps

We don't go from a 10cent small amount of rocket powder to the next stage building a Saturn moon rocket although the concept is the same - action and reaction

The blind-elephant ear-leaf really does not mean anything except there is a plant with very large leafs which resemble in a superficial way elephant ears

I do know about people who have always been blind but have had absence of sight corrected

When they are asked to draw a bus, a mode of transport they have been using regularly, their drawings only consists of the area where they boarded the bus

Even though they can now visually see the front of the bus it does not appear in the drawings until either a long time later or sooner if they walk around the bus touching the front area

But that's a digression

EXCEPT

' If you try to explain only the tip of an iceberg what you can actually directly observe, you will always fail '

Nooooo

I will be spectacularly correct in describing the TIP

I will miss in a description of the part under the water

But I will observe the tip appears to act differently to what I expect

I will deduce something else must be present

I will explore and discover the underwater section

Then I will spectacularly described all of the iceberg

That is UNDERSTANDING and KNOWING

Try them sometime

The problem with blind people and elephants is a real-world example on how much people can be wrong when they interpret something that know nothign about even though they observe it, but since they cannot see the whole picture even what is observed is misinterpreted in the first place, and if you misinterpret something thana everything else after that whatever model you make is wrong.
Quantum mechanics you cannot even directly observe the causes of observable effects, the only thing you can do is, like blind people from that elephant story, to interpret as much as you can directly observe, and nothing beyond that.
Instead, physicists create mathematical models that are untestable, instead they should interpret on what is exactly shown in experiments and directly observed and only after that create models; so even though interpretation is wrong because you cannot see the whole picture, only tiny parts of it on the surface; the interpretations that are offered by models are even more wrong because they cannot know what exactly is the cause of all those observable effects-because the causes that models offer as explanations are untestable and there are not even indirect indications in experiments of what all the causes of observable effects might be.

One can model anything about the natural world that can be deduced from reproducible observation. A proper model in science needs to make predictions that can be tested, by means of further reproducible observations. That is what science tries to do.

Of course I would agree that, if you have no observations, then any model you make cannot be tested and thus cannot be regarded as more than a hypothesis. But there is evidence in support of the Big Bang hypothesis, such as the observed isotropy and CMBR (ifI recall correctly - I am not a cosmologist). As for predictions, there is a summary here: https://medium.com/starts-with-a-ba...ction-of-the-big-bang-68ab6f4a5475#.y0cja6eqh You are quite at liberty to regard this evidence as not conclusive, however. In science, all theories are provisional and subject to refinement , modification or total overthrow, in light of new observational evidence.

You might even go further and say that, in your opinion, it is mistaken, because....niddle, naddle, noo [insert your own observations that you think contradict it].

But for it to be a "lie", as you called it in the thread title, would require that there is deliberate suppression of evidence that falsifies the Big Bang hypothesis. Do you actually mean that?
 
You have yet to state one.


Still a misunderstanding of science.


Still true. Except no one but you talks about "knowing". It is unscientific.

Our physical models of the world simply predict. The ones we have (the Standard Model) predict nature extremely accurately. That means we keep them.

Make no mistake. GR and QM are two of the most tested theories in the history of civilization.
Every single experiment has born out the predictiveness of our models with exquisite accuracy.

They don't tell us what reality is; they merely tell us how it behaves.


This is what we have been saying all along.

If you have a need to "know" what reality and nature is, you are barking up the wrong discipline. You're seeking religion.

Youa re 100% wrong, general relativity might be observable but you misinterpreted in a way that you lie to people all the time. QM is not even testable in a way that you can say that anything actually exists in the first place, shame on you-again in relativity there is no such thing as space bending, what exactly is bending are distances, trajectories and everything what is made of matter and energy what is inside an gravitatioanl fields.
Read my replies to JamesR for more informations about why thes emodels do not predict anything at all, only models that are made by observable effects in experiments are useful in making models, so models based on real evidences not on abstract concepts that do not exist ina r eal world, sir.

You can see that something is behaving, but you cannot say what exactly is behaving in the first place-this is something you lost your focus-if models claim what is exactly behaving, than the models are not based on experiments and evidences, they are based on untestable predictions of what are the causes of such behaviour-which again are untestable and unprovable.

And you are forgetting that thos reproducibile observations can be from stars, I honestly don't believe that this is any kind of evidence, neither isotropy is, it's like saying that I have proven the existence of ghosts by detecting electromagnetic anomalies-that produce truly creepy voices over my bed.
Again, when people ar eso small and arogant they say they have proven and yet they can never see the whole picture only its tiniest part-and if you cannot see the whole picture, everything you do and assume is wrong, because you cannot directly observe the entire reality and the whole picture only its tiniest part, because there is so much outside of your observational abilities and outside your realm of what you can observe and experience.

QM most certainly does account for and predict an enormous range of observed behaviours of the world.

Have you ever come across the Periodic Table? Do you know why it is laid out the way it is?

Have you ever seen a line spectrum? Do you know why the lines appear where they do?

Would you care to re-express that reply in the form of a set of coherent statements? At the moment it is not really possible to work to what you are trying to say. Perhaps a few full stops would help.

And do please stop talking about things being "proven". You have been told several times that proof plays no part in a scientific theory.
