There are several theories, all of them very speculative. One of them for example, the "ekpyrotic scenario", proposes that the big bang was caused by a collision between higher dimensional membranes (or "branes"):
http://en.wikipedia.org/wiki/Ekpyrotic

This is a script from a BBC Horizon programme which covers the topic of brane collision. The episode is called "Parallel Universes". I watched this a few years ago & found it awesome:

This is an extract from it:

And this is closely related to the ideas (may be another extract):

The brane idea is just one theory. Here are some more:

The Big Bang is a cosmological model and scientifically accepted understanding of the universe, whose primary assertion is that the universe started from a tremendously dense and hot state, and has been expanding ever since. The term is also used in a narrower sense to describe the fundamental 'fireball' that erupted at or close to time t=0 in the history of the universe.

Observational evidence for the Big Bang includes the analysis of the spectrum of light from galaxies, which reveal a shift towards longer wavelengths proportional to each galaxy's distance in a relationship described by Hubble's law. Combined with the assumption that observers located anywhere in the universe would make similar observations (the Copernican principle), this suggests that space itself is expanding. Extrapolation of this expansion back in time yields a state in the distant past in which the universe was in a state of immense density and temperature. This hot, dense state is the key premise of the Big Bang. Observations now place the age of the universe at around 13.7 billion years.

Theoretical support for the Big Bang comes from mathematical models, called Friedmann models. These models show that a Big Bang is consistent with general relativity and with the cosmological principle, which states that the properties of the universe should be independent of position or orientation.

The theory of Big Bang nucleosynthesis predicts the rates at which various light elements are created in models of the early universe and gives results that are generally consistent with observations. The Big Bang model also predicts the cosmic microwave background radiation (CMB), a background of weak microwave radiation filling the whole universe. The discovery of the CMB in 1964 led to general acceptance among physicists that the Big Bang is the best model for the origin and evolution of the universe.

This is a very difficult question because no theory by scientists comes anywhere near giving an answer. I suppose it is true there was nothing before the big bang. Nothing existed. Now that's difficult to understand. Or I should say IMPOSSIBLE to comprehend. When trying to do the impossible and understand it imagine you were a goldfish in a bowl trying to figure out the outside world. You've got it -we haven't the brain power yet. Perhaps after a few billion years of further evolution we may, unless we make another big bang and say cheerio. DB

If you play the Big Bang 'film' backwards, a point where the original singularity likely existed is approached and the laws of physics break down (as you suggest) and there is much room for speculation. Nature loves a pendulum and perhaps the Universe 'comes out' again on the 'other side' and oscillates back and forth throughout all time (recycling all our best achievements and mistakes?). However, Black Holes also collapse into singularities and seem to remain there stuck in time. Time in a Black Hole is distorted due to infinite mass density and can not be tracked by our Micky Mouse watches. Progress in solving this problem may take lots of time.

Not wishing to be too pedantic here but immediately before the big bang was the singularity which expanded to become the universe we know today.

The question really is how was the singularity formed. As any evidence, in the form of particles, energy distributions, etc, will have been destroyed by the big bang it is impossible to do any more than speculate.

Personally I think the universe forming singularity was spawned in the heavily compressed belly button of a fat guy called Morris.

Whatever reality existed before the Big Bang it might of had very different Universal Laws. Also, it's still virtually impossible in our times to explain an "event" than happened once. In modern science you need to repeat an experiment several times successfully for theory to be considered valid. Maybe that's what happened (Whoops!).

My personal theory is that every singularity form every black hole in the universe leads to the same point in space/time. Eons from now, when all the mass is the universe is consumed, the mass of this super-singularity will reach a critical point, spawning another big bang, and beginning the next cosmic cycle.

It was ..

ummmm

..hmm

How could something be made from nothing? There has got to be something....

let's see...weird huh

geez....where did all the rocks come from......

it couldn't have just grown....

unless it was alive...once....

gosh im not much of a thinker in the mornings i'll have to edit this later.

ok this is later: I was thinking about it..way back then when there was nothing, no rocks and no stardust and whatever contains in the universe today, waay back then, it had to start with some sort of gas that had been fuming for quite some time.....my guess would be that it blew up and sparked and turned into smoke which soon turned into something....i'm not sure what it is yet....i'm still thinking...well then it started out as little dust...anyways the gas just keeps repeating itself and soon all that cycle of actions acumalate and the little dusts grow and turn into rocks...

well anyways something like that...sorry i could not think any brighter today i'll try again later but i'm flying into the city today and i won't be able to get back to this till i get home in a couple days....

Hmmm...... I think before the "BIG BANG" (if that even is a true theory), there is nothing! No space, no planets, no sun, nothing!
I believe that the universe is like a cell in the human body. Maybe the "BIG BANG" is the start of this small cell that is part of a larger body of organ/organism.

Right before the big bang theory, there was a scientist wondering what could have caused the universe.
