What is the evidence and history behind the Big Bang Theory?

[Sundance]

Hello All

Reading many posts I find people not understanding the theory behind the Big Bang.

I do not agree with the BBT, but! that does not make me right. I'm not emotionally attached to any theory.

Here are some links in support of the Big Bang, later I will post against. For now maybe discuss the supporting issues.

Tango at your speed.

If anybody has links that can support the Big Bang, please post them.

Space-time inflated then matter came later and fell together. And by this then radiated. This way of creating matter with finite density allows the Big Bang to get over its limiting infinite gravity.

Space first then matter then radiation to go Bang!

What do you have about the Big Bounce? Lately I don't hear so much talk about big "bang" and "singularity". Instead i hear about the proposed cosmological bounce.

This proposal goes back in time a little before where the old singularity was supposed to be.

Do you have any links about the Bounce? do you have some explanation or support links?
Please add them to your list!

The BBT is no longer debated in mainstream science, so it would be inappropriate to debate it here. "Big bounce" and singularity issues can be discussed, but preferably in another thread. As for information concerning mainstream cosmology, we already have a thread devoted to it:
