Did the Big Bang create the most massive black hole in the universe?

Click For Summary

Discussion Overview

The discussion centers around the relationship between the Big Bang and the formation of black holes, specifically questioning why the Big Bang did not result in the creation of the most massive black hole in the universe. Participants explore concepts related to gravity, inflation, and the nature of the universe's expansion.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions how the Big Bang could start with all the mass of the universe without collapsing into a black hole due to gravitational pull.
  • Another suggests that inflation, occurring at the moment of the Big Bang, allowed for rapid expansion that could exceed the speed of light, preventing a collapse into a black hole.
  • A participant references an article suggesting that gravity did not exist at the beginning, raising the question of why gravity did not lead to a big crunch after its formation.
  • Some participants express uncertainty about the Big Bang, noting that many theories exist and that it is largely based on assumptions.
  • One participant introduces string theory, proposing that the Big Bang might result from two branes colliding, questioning the implications of such a collision on the branes' integrity.
  • Another participant reiterates the role of inflation and the unification of fundamental forces during the early universe, emphasizing the timeline of events leading to the current understanding of the universe.
  • There is a suggestion that the immense force of the Big Bang would overcome any gravitational field, leading to the universe's expansion rather than a collapse.

Areas of Agreement / Disagreement

Participants express a range of views on the nature of the Big Bang and its implications for black hole formation. There is no consensus on the reasons behind the expansion of the universe versus the formation of black holes, and multiple competing theories are presented.

Contextual Notes

Some statements rely on assumptions about the nature of gravity and the timeline of cosmic events, which remain unresolved. The discussion reflects varying interpretations of theoretical physics concepts without definitive conclusions.

I've been watching videos and reading about black holes and big
bang and many questions puzzle me. But here's one that I don't really get it.

How the big bang even started since it had all
mass of the universe in it. Therefore its gravitational pull in itself
would surpass any mass of any black hole in the entire universe.
In other words, why the big bang did not generate the most
massive black hole ever instead of expand into the universe?

thx!

This may help - but you will likely have to dig. I would think that once you start digging you will love what you find.

This "guy" seems to be one of the most down-to-earth scientists around. He has great ways of making people understand things that may otherwise be too complex or beyond many peoples ability to comprehend.

i was reading one of his books. Will take a look again, but I found this article from a similar thread than mine:

http://www.haydenplanetarium.org/tyson/read/essays/nathist/greateststoryevertold

it seems like in the beginning of everything gravity did not exist yet.

I wonder if there are astrophysics student out there to confirm the article above. Or else why right after gravity was created it did not act instantly to form a big crunch, instead of the universe.

interesting question. there are many reasons, but the main reason for such would have to be inflation. at the moment of the big bang, the fundamental forces were unified, so the energy and spacetime around it could expand faster than light. this is a watered down version of the theory but it does explain why. look if up if you want to know more.
 
noone really knows much about the big bang. many people have different theories about it so its basically just an assumption.
but once i did ask my physics teacher that "what was before the big bang?" ofc its a stupid question, because you can't answer it. before the big bang there were no dimensions yet, therefore no gravity. that's why it didnt collapse.
 
Not that this helps you but:

Something bothers me, string theory says that to branes, or 2 universes crashed into each other and created the big bang. Wouldn't the 2 branes get any scratches or rips? Because string theory says that these branes can be bent in different shapes, but not riped. It's just strange that so much force doesn't cut any of the branes. That's only my hypothesis though. I guess i'll have to dig on this one. If there is anything to dig through.

Maybe that wasn't too well thought through, and it's maybe a stupid question. But still, the only stupid question is the one you don't ask! right? As i said when i joined this forum, I am your daily resource for meaningless posts!

Correct and only once the universe had entered the quark and hadron epoch, did we really have the dissemination/de-unification of the 4 fundamental forces. This is well after inflation (when the universe's scale factor increased exponentially).
 
Since the Big Bang created all the matter & and the universe, it would of created gravity as well. That much force of the bang would break through any gravity field that's why it started coming back together after the "dust" settled?
 
Wow, that is a weird idea.

You make an interesting point, AOM.
