What caused the big bang?

It could have been the force resulting from a universal collapse just before.\n\nIf you're a religious person, then maybe it was God.

There is hard, physical evidence that the Big Bang happened. There is NO hard, physical evidence that the god of the Bible existed, exists, or will ever exist.\n\nBUT..! Belief in a supreme being of some kind is a logical belief that can exist right along with the Big Bang. Most physicists and cosmologists agree that there are no physical (as in physics)constraints that can disallow a Big Bang. Something from nothing happens constantly in the vacuum of space!!!!! At sizes smaller than a proton, so-called virtual particles pop into existence all the time. Quantum physics has shown that at these infinitesimal sizes immense amounts of energy exist which can easily "produce" new matter from nothing. The bottom line is that these physical laws exist, and the next question any reasonable person would ask is who or what made these laws, the same physical rules that make a Big Bang possible?

The discovery of  the universe expansion(doppler red shifted spectrum lines) was the source of the Big Bang theory (i think)\n\nBTW: this is a SCIENCE thread, all you Jesus Freak back off!\nthe theory of the Big Bang is compatible with the concept of a god.\nwhat was there before the big bang ..let there be light....BANG.

Well you are right most of us believes in big bang . The origin of the universe cannot be proven scientifically.The big bang can be believed some how becouse now the stars are dieng and are born .Well this may be how the universe must have been formed

String theory.  Two parallel universives touched briefly - creating the big bang.

The "big bang" is all about math. But not a zero divided by x math...a little more complex. Two competing theories are Inflation - which states that a sudden switch in the vaccuum state formed a false vaccuum that led to a positive-feedback mechanism of matter creation within a few seconds that happened so quickly that space began to expand faster than the speed of light, blowing apart spacetime into a "flat universe".\n\nThe second is the "ekpyrotic scenario" where two membranes collide in five-dimensional space and cause a huge release of energy that condenses into matter. This one's a bit scary because it also postulates that the collision could happen again at any moment and destroy the universe in a big ball of flame.

It is explosion of Gamma ray that led to the Big Bang as per the theory which is not fully scientifically proved as yet. Because, now also there are Gamma ray explosions take place in the Space from where stars and other Cosmic bodies are formed. Matter formation is billions of light years after the Big Bang.\n\nFor more, please read the fascinating book by Carl Sagan, 'Cosmos'.

When the expansion of the big bang had gone on long enough, the temperature cooled enough to where a free electron and proton could hook up to form an atom.  This is also the time when the universe became transparent to radiation, releasing the signal we see as the cosmic microwave background or CMB.

big bang. and its a big universe, we cant be all alone

Why not a big bang caused by devine intervention ?  ;-)

God created it. It is endless and boundless....this is proven by the fact that our universe is continuously expanding.\nThe Big Bang is man's attempt to explain something he doesn't understand. It is false.\nWhy? well the answer is simple.....You can't have an explosion from absolute nothing.\nGod created the universe....a simple explanation with no holes in it.

For your theory to work some 'thing' must exist before the Big Bang event and in which it could occur. Science has found absolutely no evidence whatsoever that any 'thing' preceded the Big Bang.

If you believe the theory of creation, found in all major religions, you don't have a problem answering your own question.  If you subscribe to the 'Big Bang' theory (or a derivitive thereof), I would have to ask 'Who lit the fuse?'

well let us take a "logical" look....the big bang says that there was nothing, then something, and now everything is expanding away.  So how did things get farther away than time has permitted?  Hmmm...kind of a hole in the theory.

The Very high gravitational force of attraction of the small particles that made up the universe was once shrunk into a tiny mass. Due to this a very high temp was developed that led to a huge explosion called the BIGBANG.

In theory the Big Bang happened in a complete vacuum as there was nothing before it, sound does not travel through a vacuum so no sound, nor was there anybody to hear it so, philosophically speaking, again no sound.

Any cosmologist will tell you that there is NO center to our universe. Assuming that the Big Bang didn't happen inside some "thing" else--and there's not a shred of evidence that such was the case--then we're forced to say that the Big Bang happened everywhere at once; before it there was no 'where' or anything else.
