In physical cosmology, the Big Bang is the scientific theory of how the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space (in accord with the Friedmann-Lemaître model of general relativity) as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.
Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity (for reporting on some of the more notable speculation on this issue, see cosmogony).
The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.[1]

i'm just guessing, but mebbe yes
the big bang was when a large 'bang' was made, and the universe was created, with material flying out into the new expanding universe. Of course, since no one has seen what the unvierse was like before the big bang, no one knows if it can happen again. but here are some theories.
Before the big bang, the unvierse was just a tightly compacted ball of matter, that is supposedly held together by grivty, or gravitational singularity(wikipedia). maybe in a preivous universe the universe had constantly deteriorated into a large black hole, (or many black holes) as the stars eventually exploded, some creating these black holes. and soon enough everything was sucked into these black holes, creating a ball of superdense matter. then supposedly the ball esploded, creating a big bang. this is my own theory. go to wikipedia for more info.
by the way, that idiot nmauray whatever copied from wikipedia

It is debatable. It could be cyclical if there is enough mass to pull it all back together again. If not, then it would be a one time deal.
There is a lot of discussion currently going on in this subject. You should reach the scientific magazines and websites.
