The Big Bang is by far and away the most accepted theory as to the origins of the Universe. I would say that 90% of all cosmologists and astronomers subscribe to it.
This much we know as FACT: in 1964 two guys working for Bell Labs, named Penzias and Wilson, accidently detected white noise in outer space. This static was later found to be background residue leftover from the Big Bang. FACT: All galaxies are moving away from us; this is known by the color of "shift" they emit, due to the Doppler effect. a red shift indicates something is receding. The further out they are, the faster they move. This is known as the Hubble Constant.
So: we know there was a huge explosion that has caused everything to scatter, and we can determine age from gas spectography from stars, using burned out ones as a guidline. Therefore: Big Bang, about 15 billion years ago. There is no other theory out there that meets with even a fraction of the approval this does.

It is not just a guess at all.
It was pretty much without a doubt proven this year actually that the big bang was a real event. Old light captured from the very beginning of the universe was observed and used to support the inflation hypothesis and prove without a doubt that the big bang did happen and the universe is definitely expanding all around us.
All of our evidence supports the expanding universe. WMAP is an absolutely genius project.
However, what happens after the big bang is still heavily debated; we have a general idea of how the universe we see around us formed but we learn more every year.
That and we don't know what triggered the big bang, but that doesn't need to be known to prove it happened.
And do NOT confuse theories and hypothesies. There is a huge difference. A hypothesis is an idea with very little evidence to support it. Notice that it is called the big bang theory, not the big bang hypothesis. A scientific theory is actually very close to fact, has to be supported by a lot of evidence and a hypothesis must be explored rigoriously by the scientific community before it is a theory.

This theory was never proven, but there are clues that it exists. Selestial objects are moving farther from each other, and we know this, because everytime we look at that object, it is farther and fainter. I strongly believe in this theory.
One more thing: The universe should be slowing down if indeed the big bang happened because of the force of gravity. It is actually getting faster, so gravity is somehow losing. If the universe does eventually slow down and stop, it might begin to shrink and go back to where it came from in a Big Crunch

I don't believe in the "big bang" theory, it's totally fake. How do the scientists know it, where they there when it actually happened? No, of course not. I don't believe it. I'm actually a young-earth believer. If the universe was that old (14 billion years old), the sun would'nt have survived that, it's a star, stars can't live that long.

The big bang theory fits all the observable facts. If it were proved it would become a scientific fact which will probably happen in our lifetime. It is not a guess!!!!!!!!

well that is the main theory between scientists. that a massive explosion expanded the universe and there is still recoil. but alot of believing in things have to do with faith

Uh,it would'nt be a "theory" if it been proven as fact...

there is no way to prove it, its just a guess. therefore, i don't believe in it. i won't ever believe in it unless someone somehow does prove it. and how that will happen...who knows?
