A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin. And once the fusion reactions begin, they exert an outward pressure. As long as the inward force of gravity and the outward force generated by the fusion reactions are equal, the star remains stable.
- Do black holes have this outward pressure?
- How is a super massive black hole born?
- Is it possible that the big bang was nothing more than a really big super massive black hole that exploded rather than evaporating?
Some theories that I have seen say that the big bang from an object that was very very small, yet very very dense and contained all of the mass we currently have in the universe, I just do not buy that theory, at least not yet.
In order for me to understand what the big bang, I try to understand what it was before it exploded. What would contain a universe's mass, and why? Currently we know that the greater the mass of an object, the more gravitational pull it has, size does not matter here. So when you read the topic title "Maximum Mass and the Big Bang" you could also read it as "Maximum Density and the Big Bang". Some of you here have stated that there is no reason to believe there is a such thing as a max mass, but how about density? Surely you can't just keep on cramming stuff into a pea sized ball for all eternity can you? My logic says no, there must be a stopping point.
The amount of pressure it would take to get a pound of gold into a pea sized object must be enormous, well beyond anything we can do here on earth. That is a lot of pressure and friction, do black holes generate heat? if so is that heat able to escape its gravitational pull? or is heat not effected by gravity?
I ask such questions not to get the end all answer to the universe, just to better understand it and dismiss some of my own theories. They way I can explain the universe to myself is this:
A never ending cycle of expansion and contraction, gravity wins and density losses. In other words:
big bang --> expanding universe --> gravity takes hold --> collapsing universe --> density explosion = big bang and it all starts over again.
I am pretty sure some or most of you would get a nice chuckle out of that, but rather than laughing at me, can you help me understand why it would be wrong, because I know the chances of that being wrong are very high.
