Big Bang: Whodunit?

ratiocinator

Lightly seared on the reality grill.
Existence is energy expressing in a myriad of interrelated ways. Existence is something "happening". This isn't Newtonian physics.

It's a Newtonian view of time. Nothing happens to the space-time manifold, things can only be said to "happen" if you track along a time-like curve within it.

This is the difference between being and not being. Not being is nothing happening. Being is something happening. And as such, it begs the question of impetus.

So the universe (at least the GR view of it) doesn't exist. Oops.

I think it's YOU who is caught up in Newtonian physics, here. I said nothing about time. Space-time is just another expression of energy. ... Another aspect of the "happening" that defines existence.

As I said nothing at all "happens" to the space-time and you can't talk about things "happening" (with or without scare quotes) without talking about time. Space-time isn't an expression of energy. Energy is a property of things and arrangements of things - it's also relative, different observers will assign different energies to objects.

The 'pea' reference was just a rhetorical reference.. 'particle', is more precise, even if it is vague and undefined. The whole universe, compressed into a particle.. yeah, that is believable and testable!
As I said, that was the observable universe.

the rest could be very well be infinite. Actually, evidence indicates that it is.

OK....there was an infinite `area` beyond any detection,
and there was absolutely nothing in it,
except for one point of static potential.
What could come from the described `area` ?
What could initiate the expansion of the `point` ?
What `source` could be the absolute start of the cause ?
And on and on

Hey Viole,
"Observable" is a neat word, meaning insight.
But I think you are talking about the rest of the Cosmos.
There's no `voids` out there either !
But....all in all, I'm totally confused !

That's the wrong picture. Using the GR model, space (and therefore any concept of 'area') and time are internal to the universe. It is space that is expanding from the BB, not stuff that is expanding into empty space. If you ask what's north of the north pole on the surface of the earth, the answer is nothing, but that doesn't mean that there is some mysterious place of nothingness somewhere on earth, it means the question doesn't make sense; "north of the north pole" doesn't refer to a place. In much the same way, "before the big bang" doesn't refer to a time.

Which study? Did you quote one, or are you referring to the one i sourced in the OP (originally posted by polymath, himself!)
The paper with the details of the study referenced in your OP that I posted earlier. Here it is again:
NINE-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) OBSERVATIONS: FINAL MAPS AND RESULTS - IOPscience

I did read that one carefully, and found no methodology for the measurement of 'trillions of a trillionth of a second!', some 13.77 billion years ago.. (which sounds like a research paper way of saying, 'we don't know, but have to say something!)
None of this is really layman's stuff. Understanding how they reached that conclusion may take more than a cursory understanding of cosmology and physics, but they have published their results, and I don't think think there's any good reason why they would just make up nonsense and then successfully publish a paper explaining how they reached that conclusion.

I have read a LOT of 'studies', over the years, and they has reinforced my skepticism to Gibraltar like proportions.

But people can (and will!) believe whatever they want..
Okay.

Everything that currently exists, exists as part of an ongoing event taking place. This naturally begs the question of what set the event in motion? And what, if anything, will bring it to a halt? Saying that there may not be an answer to these questions is just a pointless way of avoiding the fact that we are being confronted by the question.
But the Universe existed in a quantum state, at which point the classical laws of physics break down, so applying the law of cause and effect to this moment and insisting that something must have "caused" the Universe to expand is baseless. So the question makes no sense and presupposes a causal relationship that we have no reason to believe was possible.

A "quantum state" is still something happening.

A "quantum state" is still something happening.
But it is a state in which the classical laws of physics, including cause and effect, do not apply. So asserting that something that exists in a quantum state must do something in accordance with cause and effect is baseless. We have instances of quantum particles being birthed into existence without cause, and even examples effects PRECEDING causes in the quantum world:
How quantum trickery can scramble cause and effect
Retrocausality - Wikipedia

So to assume that something "caused" the expansion is a presumption that currently cannot be justified.

Exactly, and this is why even a brilliant mind like Einstein couldn't wrap his head around it.

The first time I watched a video explaining quantum physics, it was describing the double-slit experiment and it reached a point where what it said made so little sense to me that I assumed I must have missed something or misunderstood something, turned it off and never went back to it.

It was only about a year later that I read In Search of Schrodinger's Cat by John Gribbin and realized that the part of that video that I thought made no sense was actually true, and that I hadn't missed anything or misunderstood it - it was just so seemingly contrary to all logic and completely counter-intuitive that my brain just rejected it until I got a more in depth understanding of it.

It's a bizarre experience, and I recommend it to everybody.

It seems to me, that the faith needed to believe this happened spontaneously, without Divine Intervention, is just as great, if not greater, than believing in a Creator.

Disagree. No faith at all is required to believe that the universe was once in a hotter, smaller, denser state and began expanding some 13.8 billion years ago to evolve into the universe we find today. The Standard Model made very specific and unexpected predictions such as the existence of a uniform cosmic background radiation currently in the microwave at a specific wavelength / temperature that was subsequently discovered. Check.

Also, the specific composition of pristine nebulae including element and their relative concentrations was predicted and confirmed. Check.

The standard model also predicted the existence of the Higgs boson at a specific energy and with specific features (spin, parity), which was then found. Checkmate.

What takes faith (and the willingness to ignore evidence) is your belief.

What are the chances that the Big Bang theory made so many unexpected predictions and got them right if the theory was not correct in the main? Sorry, but the Genesis creation myth is incorrect.

Which belief is more reasonable?

The naturalistic one, since it has the evidence just reported to support it, and because it is a more parsimonious narrative, since no god is needed.

Also, the history of man includes countless examples of phenomena once thought to be of supernatural origin that have since been shown to require no god, with no counterexample going the other way.

let me see the repeatable science behind the conjecture of the universe expanding trillions fold, in trillions fold of a second.. this is possible naturally?

Buy a book or enroll in a university. You're responsible for you own education, and it should be methodical, rigorous, and comprehensive, as well as presented by experts. Discussion forums are inadequate.

And has been explained to you before, if you were sincerely interested in the science, you' have already learned it or be making plans to get a quality education. This is a standard creationist ploy - feigning interest in science that the creationist doesn't even look at when presented to him. Why? He isn't interested in learning, just disagreeing from a position of scientific illiteracy.

so very similar to the forced Indoctrination from State Mandated institutions.. who fund THEIR religious beliefs through forced taxation, and present common ancestry as 'settled science!', through constant propaganda, until all nod like bobbleheads.

This tired trope again? You are the bobbleheaded indoctrinee in this thread as you are in all of your other threads. You have no evidence to support your faith-based beliefs, which have been hammered into you by repetition in church. This is what indoctrination sounds like - "Jesus loves me, this I know, for ..." Where's the evidence? None. Just keep repeating until it's believed.

Common ancestry is a belief, with no empirical evidence. It is pounded as an Indoctrination meme, so people THINK there is, 'all this evidence!', but if pressed to present it, they can't do it.

Wrong again. Darwin gave his evidence in his famous book, and more has been added since. Learn some science if you want to argue with people who already know it. You have no chance of changing any rational skeptics mind without an evidenced argument that is factually correct.

That is why many modern graduates from our illustrious Indoctrination institutions, cannot read, spell, balance checkbooks, or critically think at all

I say it's from spending too much time in church, where one is taught to ignore evidence and reason and believe by faith. That's an excellent start to a life that doesn't respect proper education, one that is unlikely to ever learn to think critically. And then they take those habits of thought into other areas, and are set for a lifetime of poor thinking. Do you think that you are a skilled critical thinker?

There is no mechanism that can account for this conjecture.

Argument from ignorance. If we can't answer how nature did it without a god, a god must be involved. Is that good thinking in your estimation? Are you able to spot the flaw in such an argument, and why it is called a fallacy?

But you don't require mechanisms. What mechanism did this god use to create our universe. You don't know and you don't care.

Let me give your fallacy right back - if you can't explain how a god did it, there is no god. If you reject that argument, you might understand why all of you "Well how did this or that" questions are irrelevant. We don't know, and still have no reason to believe in gods.

Edit - since posting this, I encountered the following in an email:

"The 43% of Americans who oppose impeachment are undoubtedly the same 43% who reliably and unwaveringly support the President, and who are so deeply ensconced in the Fox/Breitbart News propaganda bubble that they willingly believe the President has done nothing wrong (in the face of all evidence to the contrary-- Evidence from which they are skillfully shielded, and which they are preconditioned not to believe)."

Faith based thought uninterested in evidence is not confined to religion. This, too is what indoctrination yields. Also, climate denial.
