Black Holes
Ok, I'm gonna ask something that is probably going to sound rather stupid but it is a serious question. I forgot to ask my science teachers before I left school.

My limited understanding of the Big Bang theory is that the entire universe was contained in a infinitely small point known as a space-time singularity.

If this was the case that the entire universe was compressed to the size of a pin prick or grain of sand or whatever, wouldn't that make it a black hole as from my (again limited) understanding of black holes they are a huge amount of matter compressed into a tiny space (I've heard that if you compressed the Earth down into the size of a pea it would become a mini black hole, don't know how true that is)?

Well a black hole is formed when a large enough clump of matter, with extremely high gravity collapses in on itself, the gravity pulling in additional matter.
The singularity may not have had any forces for as far as we know, it was so hot that not even matter as we know it existed, only the "strings" of reality.

Based on a brief knowledge of the singularity I got from Stephen Hawkings documentaries.

Hey brother christian, with your high and mighty errand, your actions speak so loud, I can't hear a word you're saying.

RE: Black Holes
I think... But I'm far from a specialist... That it WAS indeed a black hole but with total different properties towards it's surroundings then the black holes we know today. Why?

RE: Black Holes
Once upon a time there was a singularity. Where did it come from? It decided to expand. Why? And it created everything. Huh? What absolute nonsense!!! It would be easier to believe in a deity.

Anyone that's not a scientist in quantum mechanics or string theory really shouldn't be making conclusions. We should simply analyze the parts of the theories we do understand and see if it adheres to logic.

RE: Black Holes
A "Thinking" atheist needs to use some of that thinking when someone is b.s.ing you. It doesn't matter if they try to dress it up as "scientific" or not. You need to use rational thinking! There was, nor is no deity: there was no singularity.

Do you believe in a deity or are you just very sceptical of the Big Bang theory?

Also how much do you know about Big Bang theory, are you a physicist with intricate knowledge of the the theories behind Big Bang or do you have lesser knowledge on the subject?

We can observe through redshift that the universe is expanding, so we can logically speculate that following the time line of the universe in back to its origin, we could expect to see it collapse into a single point.

We can observe through cosmic microwave background radiation that in the early stages of the universe, it was dense and consisted of extremely hot hydrogen plasma, which cooled the more the universe expanded.

Using only these 2 observations, it would be reasonable to conclude that the universe was at one point a single point of intense heat and dense matter. And that's without even considering general relativity or string theory.


And not a single method of the various ways we can observe the universe suggests a deity. There is zero observable evidence.


So which theory is the "unthinking" one again?
