| Chairman-Mao said: I do believe in a God because something had to create the world. I find it hard to believe a "big bang" created a world and made life possible, that just sounds stupid to me. Now I'm no expert on either religion or science (relating to the big bang theory) but I choose to believe in religion instead of science. |
The big bang happened, there is just too mush evidence to back it up. I mean a phenomenal amount. And the Catholic church announced way back in the 1950's that the big bang was compatible with the Christian faith.
Anyway, the universe has A. Existed for a finite amount of time, and B. is expanding metrically.
We have observed that all other galaxies are moving away from each other by measuring the shift in colour in a similar way you would hear sounds using the Doppler effect. If the observed colour of a galaxy moves towards the red end of the spectrum then it is moving away from us, and if it is blue then it is moving towards us. All galaxies show redshift, which means all galaxies are moving away from us. The only way this can occur is if space itself was expanding.
Imagine it like galaxies being dots on a balloon, when you inflate the balloon all the dots move further away from each other. And thus we must conclude that the Universe is expanding in a similar way.
We know that the Universe has existed for a finite amount of time because of the abundance of Hydrogen gas, if it has existed in a state for infinity, then due to the fusion process going on in stars the hydrogen gas shouldn't exist.
So given the knowledge that the universe has existed for a finite amount of time, and that it is expanding at a constant rate, we can figure out this process in reverse to see that at one point there had to be a singularity and a point of expansion, otherwise known as the big bang.
And it's common misconception that the Big bang was an "explosion", it wasn't.
