Another big bang could happen at any moment!!
Pretty slim chance of it happening though.

sorry the link doesn't give much info, i'm having a look for a better link.
Maybe 'our' big bang wasnt the first then........

From standard big-bang model, to vaccum fluctuations, to early inflation theories, to the new chaotic inflation one, we are trying to understand how the universe formed and what is its fate! Are we making it too complex? May be understanding all this stuff is just out of a human mind's reach. Every new theory seems to solve the problems in the earlier one. Then they find problems with the new one and there is a search for another one.

Btw, I find chaotic inflation very interesting. Specially the part where they talk about how new universes bud off from the pre-existing ones where the pre-existing one might have budded off from another existing universe. It does not have a beginning nor an end.

I also found it interesting how monopoles could act as wormholes connecting two inflated space-time (universes).

Inflation for Beginners :

Linde has discovered that, according to theory, the conditions that create inflation persist inside a magnetic monopole even after inflation has halted in the Universe at large. Such a monopole would look like a magnetically charged black hole, connecting our Universe through a wormhole in spacetime to another region of inflating spacetime. Within this region of inflation, quantum processes can produce monopole-antimonopole pairs, which then separate exponentially rapidly as a result of the inflation. Inflation then stops, leaving an expanding Universe rather like our own which may contain one or two monopoles, within each of which there are more regions of inflating spacetime.

The result is a never-ending fractal structure, with inflating universes embedded inside each other and connected through the magnetic monopole wormholes. Our Universe may be inside a monopole which is inside another universe which is inside another monopole, and so on indefinitely. What Linde calls "the continuous creation of exponentially expanding space" means that "monopoles by themselves can solve the monopole problem". Although it seems bizarre, the idea is, he stresses, "so simple that it certainly deserves further investigation".
