From what my understandings are your information is spot on. The big bang happened along time ago and the big crunch will happen a long time from now, after that another big bang will occur.( this is not the first) we had big bangs before. It's been studied for centuries, and when ever all the matter in the universe comes back to the central location it will re occur. Pretty fascinating actually.

We do know now, that the universe is not infinite in size, or in age/life. After you exit our own galaxy, there are billions upon billions of other galaxies, black holes, supernovas, etc in the universe. The universe itself is composed of matter, anti-matter, dark matter, and dark energy. Not really sure what dark energy is, but I heard it in Chemistry. Dark matter and dark energy are invisble to the human eye, and we actually have never seen dark energy in any sense. Moving back to the idea of size and lifespan of the universe; the universe, as we all know, began (we believe) with what is called the Big Bang (the theory of a big bang is also used for the start of our solar system). As we know, the Big Bang is an event in which an explosion happend. The universe, upon it's form, was smaller than an atom. However, the universe has grown a great deal (I am sure you knew that) over billions of years. The universe is, crazy to what we recently believed, is not slowing down in its growth (this would allow for the theory of the Big Crunch, in which the universe collapses on itself), but it is actually speeding up. This has led us to believe that in (if my studies are correct, although I am just trying to remember at this point) that in around 14-15 billion years, the universe will still be speeding up, to the point at which matter itself splits apart. In this future, every atom would be destroyed, not even protons would be able to stay together. This would lead to a universe very much like the new universe (not in size, but in composition). All that will exist is energy... Large amounts of energy. So, I'm pretty sure the Earth might have another Big Bang Theory (BBT).

Do you guys have any information? I've been studying this for about 2 months now. Yes, I even discussed it with my Chem teacher. I know I'm jumping to 2 different points, but.. What do you think is beyond the galaxy? Just another one?

Sources I found this from? Google & my teacher. Look it up.

TBB created the universe not the solar system. How can the earth have a BBT?
