Big bang has evidence . When I worked at Bell labs. On the back of the small hill there was an a microwave antenna station. Right there our colleague Arno Penzias (actually our VP) and Bob Wilson received Nobel price because they observed the background temperature of the universe, which match with exactly the big bang predict about big bang residue energy.... Anyway, I think you misunderstand big bang. Big bang is very spiritually matched with Bible....
when Jesus engineered all these creation works you were not there. It does Take 13.7B earth years to reach the current "golden age of the universe", Sometimes is is hard for our mind to understand the language of God.. To understand this part you really need to know both Bible and science well. big bang is very spiritual... More closely to match with Bible than any others...
Ok need to be more clear here. We all know last year's Nobel price in physics was about accelerating expansion of the universe. In fact, the observation was done around 13 years ago. But the result was very unpopular. It really takes while for the community to digest it. Before then, most preferred scenario is that the total mass of the universe will be heavy enough and the expansion will slow down and eventually everything will come back to a singular point. The whole universe will collide and atoms will collaps into a very small size ball and eventually another big bang will take place. The cycle repeats. Life has no meaning but the cycle provide some meaning. In the process of coming back, the second law of thermal dynamics will change and entropy will only decrease instead of increase. But now this finding basically is saying entropy is only increasing. The universe is moving toward thermal equilibrium - final death - energy disperse - big cool. Whatever you say. The stars and galaxy we see today will gradually disappear. The solar system will become isolated in darkness. Everything becomes further and further away. Star travel becomes a movie dream only, since it will be difficult to catch those ever flying away stars. The time machine becomes impossible, since entropy only increases and the symmetry of time and space is destroyed. Time will only increase.
So, the universe has a beginning and it has an end and there is no more. No matter how prosper we have now how much achievement we have accomplished they will be all gone. There is a beginning there is an end and no more. This new understand will influence philosophy and philosophy will change. Eventually it will get to Hollywood. You will see movies of final generation creatures looking for energy or creating new suns for them to survive.
Back to the possibility of great crunch, assume everything will come back to a singular point can you tell me where the point is located in the universe? .... The answer is that - everywhere. Since everywhere will be getting back into that singular point. Ok. Here we have something important to say. The meaning of the answer represents an understanding of big bang. If I tell you that we spread a clothe on the table and put a lot of objects on top of the clothe. When I say collect all the objects back is different from when I say wrap up the clothe and collect ecerything back. We have no experience what means even the space is not exist. Here wrapping up the clothe is trying to explain to you what happen I big bang. Before big bang there is no time and no space.. I hope now you will understand what means no space. More exactly when the universe is expanding just as it is happening now, the forefront edge is expanding away from us over the speed of light. And right the that interface, the other side has no space existing there.
In summary, the universe is truly coming out of no where. 13.7 B years ago, it comes from a large amount of energy and following E=mc**2 to be created. This is big bang and that is the beginning and now we know there is end. What is the meaning of all of these..I leave it to you to think about..
I apologize to get into your forbiden areas. I was attracted by the EVC web site and the subject big bang ..My focus is on the subject of creation. I am not interested in genic energy. Sorry to waste your time and certain my own time too..
