What do we Know About the Big Bang?
At this stage, all we really know about the big bang, is that it most probably happened. We can see that the universe is expanding, and it seems a reasonable conclusion that it was expanding from a gigantic explosion of energy. When it was discovered that the universe was expanding from a central point, it was seen as proof by most scientists that God created the universe, at the big bang, just like it said in Genesis.
Before that, it was widely believed that the universe was eternal. Einstein in particular, had a very hard time believing that the universe began at the big bang, and there was nothing before it. He had two equations that made him suspect that something was wrong with this theory. They were the famous energy equals mass multiplied by the speed of light squared, (E=MC2), and the less famous, mass equals energy divided by the speed of light squared.
What he believed these equations meant, is that energy will always cool down into mass, and mass will always turn back into energy. The eternal cycle. The most common theory today is still that God created the universe, and it started as a singularity of infinite density, in which time did not exist, which then expanded to the universe we have today. There is no cause given for the sudden explosion except for the creation of the universe by God.
The Many Worlds Theory
The second most popular theory, is that the big bang was caused by the previous big crunch. In this theory, all the mass in the universe is sucked in by black holes, until only one singularity remains in the center, but before it even reaches that point, the weight of the entire universe becomes too much, and the atom splits, causing a big bang. The second law of thermodynamics says that all things gain entropy, and move towards equilibrium, unless something causes them not to. Some scientists say that means that this cycle could not have been happening forever, and must have had a beginning.
However, the point at which all things reach equilibrium, is a black hole singularity with the entire universe in it, which as we can tell from the big bang, is fundamentally unstable. Einstein’s two equations show that there is just as much energy released each time the atom splits, so perhaps the second law of thermodynamics does not apply in the case of a big bang. The only logical conclusion you could reach is that the universe is following the same cycle it always has, because otherwise, it could not be doing anything at all.
There is no reaction possible in a void, so matter must have always existed. No reaction is possible without time, so time must have always existed. Space and time are the same thing: space/time, and if the singularity out of which the universe came was fundamentally unstable, it could not have just existed without anything before it. That argument is trying to prove that God created it.
We do not know anything at all about what happened before the big bang, because we cannot look at it with a telescope, but out of the two main theories, one is clearly based on the bible, and religion, and one isn’t. One makes sense, because it explains why the big bang happened, and continues to happen, an infinite amount of times, and one doesn’t make scientific sense, because it requires the creation of the universe by God, and God’s existence has never been proven.
The big freeze theory continues that the universe will continue expanding, away from the gravity of itself, and the black holes which form eventually dissipate into mass-less particles. What you have at the end, is a bunch of photons flying around for all eternity, never to form into a universe again. This theory doesn’t explain the big bang, and doesn’t explain how a singularity can exist in the first place, if it wasn’t the state to which everything was destined to return by gravity.
Gravity is totally overlooked in this theory. The whole idea is a Christian idea, and they are clinging to it, to avoid the idea that God didn’t create the universe, because it is eternal. Even if the universe is expanding faster, as some observations suggest, it can only be doing so because of propulsion from the stars, which will then disappear as the stars burn out.
When matter gets to the point of absolute zero, and the electron stops revolving around the nucleus, and forms a black hole atom, there will be no propulsion, and the universe could only continue to expand at the same rate, if it wasn’t for the gravity of the entire universe pulling it back in. It is obvious that gravity will win in the end, what goes up must come down. I believe that the collapse of the entire universe is more than sufficient to provide a big bang of equal intensity, every time.
I believe that everything which can possibly happen, has happened already, and will continue to happen, an infinite amount of times, due to the nature of eternity. I say believe, because none of this can be proven, and I am not even a scientist, I have just had an interest in this issue for years. Please leave comments if you are a scientist, but understand that I do know that nobody knows for sure what happened before the big bang.
