what are the hypotheses re. the cause of big bang?

Question

i'm up for conflicting paradigms here - i ask out of interest rather than an interest in paradigmatic confict!

Answer 1

Several different hypotheses have been proposed:

1) General Relativity: The whole concept of 'before the Big Bang' fails because only time after the Big Bang makes sense. Since time is part of the universe and the universe started at the Big Bang, that was when time started also. Since causality assumes time, you can't even talk about a cause for the Big Bang.

2) Quantum Loop Gravity: Recent calculations says that there would have been a previous universe that 'bounced' to produce ours. The previous one would have extended infinitely back in time.

3) Various theories explain the Big Bang as a quantum fluctuation that 'got out of hand'. How exactly that happens depends on the specific theory.

Answer 2

because of some atomic mutation, two atoms got magnetically attracted, hit each other, and created a fission kind of thing, thus BOOM!!


Just one thing, how do we know when time started, or if anything didn't exist before the big bang, thus making the moment before the bang 0, and the actual explosion (whatever its cause), or in fact the event leading up to the big bang (or the cause of the event) a very small decimal, so there is really no start of time, because if it was before time, nothing existed, thus the start of time must have been before the actual explosion.

also, the collapse of another universe might make sense, thus making the big black hole (i mean the extreme gravitational pull which caused the previous universe to collapse) being the cause of a very compressed "ball" of matter. it might have been too compressed or heated up, and it caused it an overexertion of it, thus causing a BIG bang, which pushed everything away from the point of the pull, and made it be too far away from the reach of the pull, thus letting it expand (big picture).

Answer 3

Scientists can extrapolate to about 10^-45 seconds after the Big Bang, but before that theoretical physics doesn't provide the answer of how or why it occurred.

Answer 4

Recent results out of Penn State back up the theory that this universe emerged out of the collapse of a previous universe with the necessary math.

Answer 5

According to the standard model, there is no cause because there was no time preceding t=0. String theory (if it is correct) would allow causes such as quantum fluctuations.

Answer 6

At the moment, there really aren't any. The laws of physics don't work well at a singularity, and the big bang is about as singular as you can get.

Answer 7

In the beggining...there was a massive ball of fusion...then came God...He blew it up into pieces....billions of years later....He decides to have some fun and takes 7 days to organize bits of what He blew up billions of years ago to create what we now know as Earth and the Solar System.
