The big bang...the cosmic microwave background. I meant that we saw it had a beginning.

That doesn't prove that there wasn't a universe previous to this one.

I am, and always will be perplexed by how someone is supposed to figure out sarcasm by an online post. The last time I went through this with someone who thought I was being sarcastic, he said it was obvious because of the tone of my voice. I had to point out that the voice he was hearing was in his head...hehehehe.

Yeah, if my posts aren't there usual cogent selves it's because I've been studying a lot more, and it's really making my brane hurt.....mmmmmmm, branes...hehehehehehe

Nah, man it's cool. Fighting is not cool anyway. Hahahah brane... all branes are created equal.

Can you give me some other explanation for the cosmic microwave background?

And, we don't know what happened before the big bang that created our universe, because there wasn't anything. So, unless we can perceive higher dimensions or travel back in time, we can't know if there are other universes. Unless of course our universe begins to collide with it...then we would cease to exist so I hope not.

This universe could also just be contracting and expanding infinitely...we just don't know. And, where did the energy from the big bang come from? Something we will probably never know.

There are various cyclic theories... The beginning of our universe may not've been the first one.

And speaking of universes colliding, the possibility of a vacuum metastability event is my personal favorite universe ending scenario. Everything as we know it ceases to be spontaneously and without warning. Yay...

Lack of another explanations is not positive proof for your explanation. The simple fact is that no one knows how the universe started, or whether it started in the first place. If they did, we wouldn't have all of this confusion. That simple fact is enough for me to conjecture about the possibility that the universe has neither a beginning nor an end. Until someone provides a reason why the universe cannot have been infinite, I can't help but hold that as a distinct possibility.

I like the theory that the universe is contracting and expanding infinitely because the force of gravity will eventually be too strong. Particle physics makes me think of us like particle in another grand scheme, followed by another and another.

That is a great one, I personally like being instantly evaporated by high energy waves with out a moments notice. The auroras will be beautiful...for about a second.

I began to think like that. And, if you remember, I tried to make a prove proving the lack of other universes if our universe was infinite. But, then I remember the mass of evidence compiled by the big bang theory, and I realized that the universe was most likely not infinite. You have to acknowledge that the universe is constantly expanding. If it wasn't then everything would collapse back again to singularity because of the force of gravity. This can be proved by Hubble's expansion law. This is the law that dictates the Doppler effect. And, as we look to space, we see all red light coming towards us. This means that the all the matter in the universe is moving away form us.

I like that one as well. The universe is like a balloon or something, expanding with a bang, then shrinking back together and bouncing back out again.

I was just talking the other day that if I had to chose my death, I would be vaporized. Or shot into the sun.
