SUMMARY

The discussion centers on the origins of the universe, specifically the implications of the Big Bang and the evolution of physical laws. Participants explore the transition from a hot, dense state to the current universe, questioning how physical constants and laws emerged simultaneously with the universe itself. Key points include the distinction between states A and B, the role of quantum gravity, and the implications of chaotic inflationary theory as proposed by Andrei Linde. The conversation emphasizes the speculative nature of these topics, highlighting the lack of definitive evidence prior to the Planck Epoch.

PREREQUISITES
  • Understanding of the Big Bang theory and its implications
  • Familiarity with quantum gravity concepts
  • Knowledge of the Higgs mechanism and symmetry breaking
  • Awareness of chaotic inflationary theory and its proponents
NEXT STEPS
  • Research the implications of the Higgs mechanism on particle physics
  • Study the principles of chaotic inflationary theory by Andrei Linde
  • Explore the current advancements in quantum gravity theories
  • Investigate the Planck Epoch and its significance in cosmology
USEFUL FOR

Cosmologists, physicists, and anyone interested in the fundamental questions surrounding the origin of the universe and the nature of physical laws.

I was just throwing that idea out there I suppose. Like a good buddy of mine once said, 'I'm pretty sure the physics works out.'

Well, keep in mind that personal speculation is seriously frowned on here.

Yeah, I do understand that speculation on this forum unacceptable, but I don't think either of you guys understood what I was trying to say- in regards to the original question of this post.

Since we clearly don't understand what you were saying, I'd have to agree that we didn't understand what in meant in regards to the OP. :smile:

Please don't do things that make me agree w/ Drakkith. I hate agreeing with him :smile: :smile: :smile:

I wonder... can we "fix" you more than once? I don't know, but I'm willing to try. :-p

ryan albery, what Drakkith is referring to is my avatar. He thinks I'm actually a dog. I've tried to explain to him that dogs can't type but he doesn't get it. He thinks I'm unusually smart. For a dog.

Physics is reality, by definition, that's all I'm trying to say... for being a dog.

I don't remember ever discussing your mental aptitude.

as much as I know phinds from being on this forum his not only smart his also sarcastic on many occasions , how does that go together with the description of a dog? He also has an avatar of a white polar bear , probably an alter ego for a dog. :D
Now that you are done trying to find something funny about my infantile jokes,..

Back on the topic, I would somehow like to agree to what ryan allbery said , and quite frankly not that he is the first one who has ever said this , I think the idea is as old as everyting around us.
Yet the question is perfectly legit I think, how does a universe or space time while being literally created on spot and rapidly changing evolving and all kinds of things and yet it falls just into the right proportions etc so that we can look now back at it and say , a universe was born and yet here we are.
Without the assumption that the laws must have come if not before it as tere were no time hence no space then atleast , well ok this is the tricky part , how do the laws come before the space time itself?
Well normally when we build something we always make schematics and calculations first and only then we do it otherwise nothing but chaos comes out , but it's hard to apply such terminalogy to the birth of the universe as if there was no time before it then nothing could have been made or changed or etc.Yet somehow in the context of the universe the laws happened to fall out just right on the spot together with the mass and space itself so that all could form as we see it.

After all I said , try to think about it assuming no God , any metaphysical force involved, any previous universes etc etc , assume the best model we have for now , assume nothing before it, sounds kinda weird doesn't it?
