IsaacGS Wrote:The problem with all this "The universe is so big, something MUST have created it!" is that you're thinking like a human. You're assuming that an effect has to have a cause, and that's not the case. It's ridiculous to talk about "what was there before the universe?" because there was no *before*. Time started when the universe started. Without the existence of time, there can be no "before".
To back this up:
All theories of cosmology are formulated on the assumption that space-time is smooth and flat (well, almost), ya? Problem occurs, cause at Big Bang, the density of the universe and the curvature of space-time would have been infinite. Umm, flat does not equal to infinite curvature, right?
Therefore, even if there were events before the Big Bang, we couldn't use them to determine what would happen afterwards, because predictability would have broken down at Big Bang, if you get me.
If that's the case, we only know what has happened before the Big Bang, and we cannot determine what happened beforehand. As far as I understand, events before the Big Bang can have no consequences and should thus not form part of a scientific model of the universe. That's why we cut them out of the model and say that the Big Bang was the beginning of time.
This means that questions such as who set up the conditions for the Big Bang are not question that science addresses.
Simply put (tl;dr): Science doesn't bother to find out who or what created the Big Bang because it doesn't matter and have no impact on our lives.
