I'm sorry Gravage... but so far you have presented zero compelling evidence for any of your claims.
Can a person sense a magnetic field? Typically, no... but there are animals that can. A person probably COULD feel a magnetic field, when it gets amped up to the point that it starts ripping the iron from their blood...
You claim you have "real evidences"... why not post them here? What do you call "real evidence" - photos? Video? You dismiss math (which is ironic as it is one of the fundamental basics of scientific proof), yet have presented no alternative beyond what appears to be idle ramblings...
Did I do a third rate job with the analogy? This is just more empty, hand-waving ranting. You have just mouthed a bunch of words that are a vague set of assertions.
More than that, the assertions are patent nonsense. But I shall play along with you for one more attempt. When was the last time that real science existed?
I imagine the old school scientists scoffed and mocked the newfangled "microscopes" that appeared to show supposed microbes and bacteria - (which ushered in a new age of medicine and biology). They rued that science had come to an end because you could no longer see and experiment on real things - just things that could only be viewed second-hand through some infernal device.
After all, microbes are only theoretical. It's not like it'll ever be real science.
Telescopes. How can there be any science about something you can only see with a contraption? No, science can only be done on things we can see with our own two eyes.
Those pinpricks in the black canopy of the night sky are only supposedly stars; we'll never really know. We'll certinaly never be able to build mathemtical models of their structure and evolution. It certainly won't involve knowledge beyond that of a high school student.
And spectrographs. Now there's some sketchy stuff. You can't examine the compositon of the sun with your own eyes, therefore we will never know what the sun is made of. Did you know that helium the element was first identified via spectrographic observation of the sun?
Seriously though. You are comfortable with microscopes, telescopes and spectrographs, right? Because they've been part of our tools for centuries. They're not just for scientists any more.
You think this next wave of tools and mathematical models is too ephemeral, but that's only because they're new to you.
Scientists have always been ahead of laypeople when it comes to science. Laypeople have always thought the latest science was not to be trusted.
We are progressing beyond our feeble eyes. That is what it means to advance our knowledge. We're not Early Man on the savanna, examining leaves by daylight anymore.
Gravage:
It has become fairly clear to me that you don't have much idea about how science is done, or how technology is made. And your ideas about energy are ill-formed and not self-consistent. You contradict yourself.
So there's no "pure energy" substance, after all? Have you changed your mind on that? You've said on multiple occasions that energy is a substance. Now, though, you're saying that it is not. Or maybe you're saying that energy is lots of different substances that can change from one thing to another - is that it?
Can we at least agree that you can't show me any energy that I can see?
It follows from your own argument that your invisible energy, being unobservable, is a useless "mathematical" concept, doesn't it? You're claiming that this thing called "energy" exists, and yet nobody can see it. Aren't you guilty of the same kind of mathematical trickery you're accusing physicists of doing with their mathematics? You're just inventing a mystical substance whose properties you can't even describe clearly.
Can you actually see energy in nature? You're telling me you can't show me any pure energy in nature. So, isn't energy just like those numbers, then?
Also, it seems clear to me that I actually have 5 fingers on each hand, and that's something I can directly observe with my eyes. But you seem to be telling me that the number "5" is meaningless because it's not "in nature". What are you going to replace numbers with, then? What do you tell people about your fingers? "I have a bunch of fingers on my hand. There's no way to know how many there are, because numbers are something that doesn't exist in nature. Nobody can see a number." Is that what you'd say? Or would you perhaps tell them that numbers come in lots of different forms: 5 fingers is different from 5 jelly beans, for example. But then you've already said that energy comes in lots of different forms. So isn't energy like numbers?
So now you're saying that you don't know what energy is, but the one thing you know for sure is that it isn't a number.
You're not making a very convincing case here. Can you see that?
What do you think? Is energy crucial for the existence of the entire universe? This invisible substance that you don't know what it is? I would think that something so crucial would be better defined.
I doubt you can explain what "heat" is any better than you can explain what energy is. You can't hold heat in your hand, can you? You can't see it. You can't bottle up a quantity of heat. So maybe heat is just a number, too.
What? You say you can feel heat when you stand under the hot sun? Does that mean that some mystical "heat substance" is flowing from the sun to your skin? Physicists explain what is happening there with references to photons of light hitting your skin and causing the atoms there to vibrate, etc. etc., eventually causing nerve signals to your brain so you feel warm. But that description doesn't include any "heat substance" or "energy substance".
Ok, so let's see. So far you have said energy comes in different forms, including heat and electricity. And previously I talked about chemicals in a battery and light. So is energy just whatever you want it to be?
You can't show me a bottle full of energy, can you? If you can't then you haven't isolated it. If the energy is in something then it's not isolated - it's part of the thing it's in.
I've never seen any isolated energy. Have you?
Why do you feel the need to insult me? Can't you tell from my posts that I'm not stupid? Are you a child, or an adult?
Er... no. I haven't said that beings of any kind create space. You, on the other hand, said that everything in the universe was created. You didn't say by what or by whom.
I don't think it has to be higher-dimensional. I was just giving you one way to visualise the expansion of the universe. Another way is to think of the universe like a loaf of sultana bread that is being baked in an oven. The sultanas are the galaxies, and the bread is space. As the loaf bakes, the sultanas all move further away from one another.
You say you think the universe is infinite and eternal. So, picture that loaf of bread as the infinity of space. The expansion is still described the same way, with no need for higher dimensions.
(Part 2)
Do you believe in electrons? Nobody has ever "directly observed" an electron. Does that mean electrons don't exist?
How do you explain electric currents?
Do you think we have no idea how electricity actually works, and that it's all trial and error?
The bolded part of this quote is what struck me most forcefully in your latest series of replies. I find it virtually incomprehensible that somebody could seriously believe that all technology is based on trial and error.
Are you for real?
Suppose you wanted to build an electric motor by trial and error. Assume you know nothing about those silly mathematical and physics theories of electricity and magnetism.
Where are you going to start in your trial and error process that will end up with a working electric motor? How will you know what materials to use to make the motor? How will you know how they should be put together?
Do you seriously believe that somebody just invented an electric motor one day by pure accident - trial and error?
Also, would it be worth your time trying to build a time machine, or a teleporter, perhaps? There's no way to know that it isn't possible to build either one by trial and error. So, maybe if you try enough things then one of them will eventually result in a working time machine. Do you think so?
How about that smart phone you own? Do you think all the hardware got that way by trial and error? And all the apps?
Have you ever tried to write a computer program of any kind? If so, did you do it by trial and error, or did you start by learning something about the programming language and the tools you could use to make the program?
Seriously?
Are you honestly telling me that you believe that somebody invented the digital camera without using any scientific theories or mathematics? Did they just slap parts together at random until eventually - viola! - a working digital camera appeared?
And the Large Hadron Collider ... that was just a bunch of scientists and engineers randomly assembling billions of dollars worth of equipment in the hope that the resulting machine might do something useful?
This is the way it is, is it?
If I have 2 apples in one hand, and 3 apples in the other hand, mathematics tells me that if I put them all in the fruit bowl there will be 5 apples there.
You're telling me I can't know whether there will really be 5 apples in the bowl, because I can't know what is true of false from doing maths. When I add 3 and 2 to get 5, you're telling me I'm just meaningless playing with numbers. It's just dumb luck if I do end up with 5 apples in the bowl, I guess. Trial and error.
How do you manage your money, Gravage? You can't know what is true and false about your bank balance, because that's just a number, you're telling me.
So if the maths predicts that a certain minimum frequency of light will be needed to for a metal to emit electrons, then it's just dumb luck if that's what I happen to observe in an actual experiment? It's nothing to do with whether the theory that allows me to make the prediction is any good?
Didn't I just give you an example of a testable hypothesis? The maths predicts that the minimum frequency will be x, and then I go and do the experiment and find that, indeed, the minimum frequency to make it work was x. Didn't I just test the theory?
What alternative approach would you use? Trial and error?
Can't you appreciate any of the benefits that science has given you? Really?
Science and technology are tools. They are have no aims of their own. Science doesn't kill people - people kill people.
I'm still not sure why you have it in for science.
You make a lot of assumptions about me.
Do you believe that scientists are not human beings like you?
(Part 3)
I'm not sure why you're targeting science with your complaints. In fact, you seem to have much more general issues with the society that you live in. You can't lay the blame for all your problems onto science.
A few quick points. First, population is increasing most rapidly in the least educated societies with the least access to science and technology. Second, science has greatly improved the productivity of the world's food resources. There is more than enough food to feed everybody in the world. Third, most people have a choice whether to exercise and keep themselves healthy, or to eat junk food and spend all their time on the internet or whatever. Fourth, stress comes from lots of different facets of life; it can hardly be put down to evil science.
I'm not sure how much you know about bubonic plague, but I assure you it would be a horrible way to die. Fortunately, science has meant that bubonic plague is no longer a major health issue in the modern world.
When it comes to things like climate change, in fact the stupid scientists are saying quite loudly that we shouldn't rely on technological progress to save us. We need to act to change the way we live, before it's too late.
Try building a microwave oven by trial and error. Try building a car engine. Try building an aeroplane. Try building a house by trial and error - you'll get a poor house - or at least a very expensive one - as a result. Try building an x-ray machine by trial and error - where will you start?
Surely you can see that it is madness to think that technology is all created by trial and error. In the absence of scientific theory, most modern technology simply would not exist.
(Part 4)
So radio is impossible because it's 100% impossible to isolate a particular frequency of radio waves from the rest of the radio waves in the environment. Right?
No. You can actually hear the sounds of particular gravity waves online. Luckily, gravity waves happen to operate at frequencies that the human ear can actually hear. And the sounds turn out to be very specific. The sound of two black holes merging is different from the sound of the collapse of a white dwarf star, for example.
But you missed my more general point about how unwanted "noise" can be eliminated from complex signals. I gave you the analogy of radio waves, and by analogy the same kind of thing is possible with gravity waves.
But I do. The theory tells me what they should look like and what effects they should produce in a detector such as LIGO. Other theory tells me what they should sound like if I amplify them and play them through a speaker.
So, when LIGO detects something, I can check whether that something looks like anything the theory predicts, or whether it is something else (perhaps extraneous noise of one kind or another, which can never be completely eliminated). And, importantly, it is possible to extract the signal from the noise - to "tune" the detector like you tune a radio to a particular station.
What else could they be misinterpreted with? How could they be replaced by something else, and what would that something else be? If you make these kinds of claims, you need to be specific. Vague, unsupported claims are worthless.
You're wrong again. Scientists don't tune their gravity wave detectors by trial and error, like you think they do. They build them with reference to scientific theories. And those theories do tell them where to tune the detector to look for gravity waves.
And all you can do to listen to the radio is to get in your car and drive down to the studio so you can hear the presenter's voice directly.
Are you claiming that scientists faked the detected gravity wave signals? Got any evidence for that?
But nothing can be proven with "some mathematical crap" - apart from other mathematical crap.
Experiments tend to either support theory or refute it. When the experiments support the theory, we think we have a good theory. When they refute it, then it's back to the drawing board.
You seem to have a real problem with this basic aspect of how science is done.
Are you claiming that there is real-world evidence that refutes the big bang theory? If so, then present it!
Do you believe that the only things that really exist are things you directly perceive with your naked eyes and other human senses?
Do you believe in ultraviolet light? You can't directly observe that.
Have you ever been sunburnt? Tell me how you explain sunburn without referring to things that are not directly observable.
There is no way you prove the existence of any subatomic particle in any way.
What material is super-conducting at 400C? If you supply me that information I GUARANTEE that I will make sure that the world knows about it and knows that you are the person that discovered it!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.
Once again you betray a total inability to behave in a way that would even remotely look scientific. Please, if it is not to much trouble, when specifically in time and place and personality did this occur.I'm just stating facts, the real science existed when people could actually test and directly observe what they tested.
Yes. We do....we have technology that enhances areas that we cannot see...
Gravage:
You have posted a lot of material above, in posts #341 through to #361.
Could you please clarify whether all of those posts are by somebody else, or whether any of them (or parts of them) are your own thoughts or work? Are they all from the same source? Can you link to the source?
There are a lot of really basic errors in those posts - too many to know where to start. If these aren't your work, it is probably pointless to start in on them.
The other question I would ask is: do you understand all the material there? And what do you know of the physics they are commenting on? That is, have you taken some courses in relativity yourself, or read any standard texts on the subject? Or is all your knowledge from self-styled debunkers of relativity?
I intend to respond to your earlier reply to me, because at least I know that was your opinions and thoughts.
Yes. We do.
That bears repeating:
...we have technology that enhances areas that we cannot see... full stop.
Once again you betray a total inability to behave in a way that would even remotely look scientific. Please, if it is not to much trouble, when specifically in time and place and personality did this occur.
I don't know what you think constitutes direct observation, for your grasp of facts are so abysmally deficient that I don't even want to guess. So you tell me:
Who was one of the last scientists to practice real science?
What were they studying?
When to within a year or two did this happen?
If you cannot do this I shall move heaven and Earth to see you permanently banned from this forum.
Origin showed you a cloud chamber, which shows direct, naked-eye evidence of things that our subatomic models predict.
Evidence!
That evidence seems to be right up your alley. But I bet you will reject it, because it is just more icky-poo science.
You cannot actually know from what exactly are tracks are made in the first place.
Have you any ideas of what causes the tracks?
I agree you cannot see the particles but you can see the tracks
So would it be your position ' I don't know what is causing the tracks '?
Would that be your answer?
