The True Origin of The Universe?

Someone once described string theory [and its derivitives] as late 21st century physics, that accidently fell into the 20th century...Stephen Hawking??
Still worth considering on that score, and until we have the necessary means to examine and observe at those quantum scales.

Sort of the scenario that I was speculating on. Whatever conditions were like at and pre BB, whether fluctuations in the quantum foam, or as you speculate, "chains of Universes", it would control the laws and constants we presently have.
For instance, if we look at the quantum foam scenario, some other fluctuations may arise [analogous to a soap bubble in a bath tub] only to burst before it expanded to a size where matter evolved and life evolved from that inert matter.....Other bubbles may have arisen, and be driven to enormous size by conditions, and subsequently again bursting before life can arise.

Hmmm, Interesting....I have not actually heard or even envisaged that type of scenario. Why wouldn't any previous Universe's conditions, not influence our one, if that picture is correct.
I mean are we not looking at a wormhole type of scenario and ERB?
So why would conditions not "flow"through, so to speak?

My picture of a singularity, is just a region of space-time, at the quantum-Planck level, that has the smallest volume allowed, and at which GR and the laws of physics do not seem to apply.
A singularity is not in itself "Infinite", but "MAY" lead to Infinite quantities.
What I'm describing is a physical singularity.
A mathematical singularity is a different beast.

Agreed.


Just some food for thought. Not sure if I read this somewhere, or if it is just my own thoughts on the subject...probably the latter.

The great Fred Hoyle coined the term BB, in a derisive attack on the model.
He proposed Steady State.
My thoughts on why he was of this frame of mind are that despite being otherwise a top notch scientist, his problem [in my opinion] may have been that the BB model, was leaving the door open for creationists and other God botherer types, in the fact that cosmologists could not explain, and still cannot explain, the whys and hows of that precise moment of the BB itself.
They [the God botherers] used that to invoke their deity of choice]
Therefor he could not give them that opportunity and along with Bondi and Gold, came up with Steady State.
Mainstream science on the other hand, and despite that "opening", but to its credit, accepted the way the evidence pointed to and upheld the scientific methodology despite the obvious forthcoming take from the religious types.

Thank you, AlexG!

That is what I honestly consider the answer to be.

Simple question...simple answer.

That simple answer, and the fact that it was not proffered on SciForums until the 95th Post, "speaks volumes"...so to speak.

Thanks again, AlexG, for simply : Objectively considering not only the question, but also your answer.

Well that's simply because it is just one opinion dmoe.

I differ slightly and see the laws and nature of the Universe dependent on the conditions at the instant of the BB, which evolved space and time.
[see my previous post for other examples.

But it is nice to see the myths discussions left out where they should be.

Probably due to the complexity and preamble of the OP.
Irrespective Alex, I see the following speculative assumption at post 39 interesting, and more logical.
What do you think?

 

I think that the question was not 'what was the origin of the universe', but what would change today if it was this or that. The answer is nothing would change. The way things are is the way things are, regardless of the reason 13.7 billion years ago.

Personally, I'm an atheist, and see no need for the existence of god to explain the universe. If the net energy of the universe is zero, then a quantum fluctuation can explain the origin.

 

Probably agree with that Alex, but the "what would change if it was this or that" included that mythological concept of God from the OP, and I see that as a non scientific alternative, albeit a popular one.

I also totally agree with the notion that God and the need for one is now redundant, and getting more redundant as cosmology progresses.

 

I think Hoyle was simply more of a mind that the universe always existed.


As long as they have the attitude they do, the the God botherers will always find an open door or they open doors which are not there. If Steady State had prevailed, they would find some way to claim that as evidence of their godfantasy. If we ever do explain, the whys and hows of that precise moment of the BB itself or if we somehow find that BB is incorrect, after all, Bible Babblers will grab either & twist it to pretend to support their bullshit.

 

Yeah, sure they would, I agree.
I probably also see a future QGT giving us the why and how of the BB, and I'm pretty sure the BB model itself, will be contained in such a QGT.

 

I really think that it started when time was borne. For me the question is: when was time born? Cause i dont believe in any creator, i'm not an astronomist, or a scientific but i think time is responsible for everything. In the universe or in this world.

 

You have nearly got it.
The BB theory is a theory of the evolution of space and time.....not as most lay people imagine, matter and energy, although there certainly was energy associated with space.
Science gives us a good picture as to how things evolved from 10-43 seconds after the BB itself. Before that we know zilch. After that, we can understand, although the closer to that 10-43 seconds we are, the less certain.
Still, what is known, is in conjunction with the known laws of physics and GR.
Space and time, is now more correctly known as spacetime...the 4 dimensional framework that is the backbone of the Universe, in fact it is the Universe.

 

James R.:

I read those "comments" once...in your next to last reply

 

Post #89...!?

 

And then you went on to post religious questions in a science thread. How objectively scientific is that?

It doesn't get to be called objective by proclamation. It has to actually be objective. There are all kinds of ways that Creationists invent excuses for pretending that Creationism trumps Science. But I think calling it "objective" is an innovation on all of that.

On Creationism? I doubt it. If you say you're a Creationist and I classify you, rather objectively, as an adherent to traditional myths invented by superstitious people, to explain phenomena for which they had no science. . . how interesting a discussion are you going to find in that? I doubt you really want to talk about the tablets at Nineveh which prove that the Flood Myth originated in present day Iraq, among the enemies of the proto-Jewish people who I presume you consider your cultural forebears. Or that you want to talk about the inscription on the obelisk by Hammurabi which lays out the first detailed set of laws ever known to have been written, which trumps the Christian, Jewish and Moslem claims to having received their laws directly from God. (As if physical evidence is needed to do that.) And so on. We can talk about evidence all day long, but if we're going to prosecute an objective treatment of it, then we're going to proceed scientifically, which completely rules out religion. I don't think you're really looking forward to that. Are you?

I don't think you're going to get what you want. But you might get what you need, which is a little science. Unfortunately I don't think it has anything to do with cosmology. As with all such threads, they really belong in a science thread that dissects the origin of religions, with a focus on the evidence, which are warehouses full of artifacts, plus of course all of the relevant literature from scholars of antiquity who lend a wealth of information to the question. But most of all, any objective treatment of this subject needs to treat the evolution of Anabaptism from the fringes of the Protestant Reformation to its insinuation among American pioneers who were just plain dumb and extremely gullible, living in the wilderness with no exposure to learning. That's the tradition that you appear to be appealing to, insofar as you've referenced the stupidest of ideas ever to occur to people, which is to treat myth, legend and fable as literal truth, and then set up rules to govern society based on such principles.

As for Cosmology, it makes no difference what Carl Sagan thinks might have happened before the Big Bang, if the prevailing scholarship is correct, which tells us that time and space are created in the Big Bang. You might get some mileage talking about the rationale for sequencing the epochs that occurred after the Big Bang, which is perfect for this Forum, but I doubt that's on your mind at all. My point is, there is no point in asking what happens "before" the creation of time. That kind of discussion also has nothing to do with cosmology, but may be better suited to a thread on philosophy, although it's a niche area probably better suited to people with good math skills (since it deals with boundary conditions and limits).

To make clear that I’m not disparaging Carl Sagan, who was the Bill Nye, Science Guy of the ... 80s? If there were any quote I would pick from him to characterize the question you’ve posed, I would take the one from Contact where Jodie Foster’s character (in the book, the film didn’t do this justice) is arguing Religion vs Science with her boyfriend, who becomes the manipulative preacher. The part I thought was quintessential Sagan is where the scientist asks: if God were actually trying to give us as message, don’t you think he would have just carved E=mc[sup]2[/sup] on the Moon, so when humans got to that point it would be clear that such a message were sent, and that such a God actually existed (words to that effect). That’s the kind of logic that moves people.

Other than that, I can only guess you have no use for my comments since they pretty much trounce the unstated agenda here, which is Creationism. My assumption is that you will either ignore them or follow up with your 99 questions "Where did I say that" etc. instead of actually engaging any of the facts I presented. Do you see the problem I'm seeing? I doubt it. But I'm always willing to see anything through with any poster who has an ounce of sincerity. I'm just not sure if that includes you, because you're always harboring all of these religious ideas along with sort of coded attacks on science. And I think there is something wrong with your science preparation, I'm just not sure what it is. There’s nothing wrong with that, it’s just that you should probably scale back your expectations about the level of technical information being exchanged in dialogue with you . . . if in fact that is what you are seeking.

 

OK, accepted....My speculative scenario is entirely different.
But doesn't your "chains of Universes" scenario require WH's? I have often speculated myself, re the BB being the back end of a BH in another Universe, with an outpouring of space and time, into our Universe.
But that idea was deflated by a GR expert on another forum, whom I found to be knowledgable and reputable.

Yep, OK, at the quantum/Planck scale certainly.
But I just see that as just limiting any constructive speculation within the bounds of GR and known physical laws.
Maybe once space and time form through and past the wormhole and ERB, we once again have the more familiar laws of physics and GR.

I see the singularity as real....I see it as real as spacetime. I see this "ündefining"as you put it, as simply spacetime at the quantum/Planck level...a small [the smallest volume of spacetime allowable] volume of spacetime, in which our laws and GR appear not to be applicable, or at least we cannot "observe" them.

The predictions of GR [as I prefer to put it] just get less accurate, much as Newtonian physics gets less and less accurate, when larger masses, higher speeds are discussed.

When you speak of a BH between the EH and the Singularity, what have you really got? Just critically curved spacetime, that may along with mass density, move to infinity.
Although I don't believe that is so, and the true nature will be revealed with a observable QGT.

I would love to say, been there, done that. But as you well know, I aint no scientist, but at the risk of being labelled a suck hole and science cheer leader, commend you on your approach.

 

Can you elaborate on that Trippy?

 

@ Aqueous Id

1.) - The "religious questions" that you seem to be "Subjectively" referring to were a part of the "premise" of the OP.

2.) - You should know the difference between "Subjective" and "Objective".

3.) - I have never "said" that I am a "Creationist" in any of my nearly 1,800 Posts on SciForums.

4.) - I have, in my nearly 1,800 Posts on SciForums, stated very succinctly that I am NOT, in any way shape or form, a Theist.

5.) - Any assumption, presumptions or intentional mis-characterizations you manufacture are the result of your own apparent inability to Objectively Observe reality.

6.) - Your statement, Aqueous Id, : "I don't think you're going to get what you want". I perceive that as a statement professing what you hope to achieve by Posting in this Thread.

7.) - As I have related to you before, Aqueous Id : I have no interest, need or proclivity to "play your little games"!

 

And then we have their closet supporters.

I've said words to that effect a 100 times....well at least 99 times.

I see some underlying agenda, don't really know why exactly, so one can at best form a logical most likely subjective opinion.
