BOOM! Goes the universe
Okay, so if you didn't know, the big bang is the theory on how the universe was created. So, if you've ever asked yourself "How did the universe get here?", no one knows the answer. Sure, there are religions that have there own beliefs, but no one knows whether they're ACTUALLY true.
According to astronomers, the universe started about 14 billion years, and they beleieve the BBT is something that happened to cause this "start". Back then, all the universe was packed together in one, dense point, called a sigularity. This little guy was full of EVERYTHING, and I mean EBERYTHING (that was for you, cheebs). Now for some reason, it decided to explode, sending not just matter, no, but space AND time in different directions! I guess time really does fly! *corny drum sound*
It was REALLY hot at first, about 10,000 million million million degrees. Three millions! That'll burn your marshmallow... but anyways, eventually (and kinda obviosuly) the universe cooled down and things like stars and galaxies began to form. All the matter began to expand, and it's still expanding to this day!
Sorry this picture is so small, it refused to cooperate!

This is what we would look like if the universe hadn't have cooled down.
So, I was watching brainpop, and they gave a really good example as to why the planets and stars and galaxies and whatever are getting father away from each other. So you guys know raisin bread, right? (YUCK). So when your baking the bread, it expands and the raisins spread apart, like the planets and stars and galaxies and whatever!
Okay, I admit it, this looks yummy.
The BBT was first propsed by Georges Lemaitre, in 1927. A few years later, American astronomer Edwin Hubble came out with evidence supporting the BBT. His observations said that not only is everything in the universe moving away from everything else, but that all matter had taken the same amount of time to get wherever it is, all starting from a single position. Well, gee, Mr. Hubble, just steal the show why don't you?

Other things since then have given us evidence as to whether the big bang actually happened. One telescope was able to look so far into the distant universe that it actually found leftovers of radiation caused by the big bang! You gotta admit, that's "pretty cool". (joke with cheebs again)
Well, anyways, farewell for now. SuperSaraSuperBye!!! Sorry for the shortness of it.
