I just had a thought. What happens if big bangs and universe going back to one single point happened in cycles? Basically universe goes band it expands then it slows down and the force of gravity pulls it back into one mass? What are your opinions? Did the Universe begin with a bang or just expansion?
i think the universe came form a preexisting universe' black hole... after there black hole age... i colapsed in on itself expanding to emense proportion and with all matter crushed... i had to start from the beguning

And why do you think that? Seriously people, stop spouting out ideas that don't have any reasoning and proof to support them.

Given the likely shape of the universe this is unlikely to happen.

The expansion rate is speeding up not slowing down. This is thought to be the result of dark energy.

No it wasn't a bang The term "Big Bang" was coined by Fred Hoyle, a detractor of the theory to make it sound bad. The name was popularized and stuck. So originally it was meant to be misleading.
Considering when it started expanding it was faster then the speed of light
Still is.

That is one hypothesis that currently exists. It's thought hat we may be existing inside a black hole. This is though because of certain similarities between black holes and the big bang and our universe.

You guys seem to be confusing hypothesis with theory here.
Such at two universes (membranes) colliding resulting in the big bang is one hypothesis of how it started. It's no more the big bang theory any more then abiogenesis is the theory of evolution.
However, the results of the WMAP mission and observations of distant supernova have suggested that the expansion of the universe is actually accelerating which implies the existence of a form of matter with a strong negative pressure, such as the cosmological constant. This strange form of matter is also sometimes referred to as "dark energy". If dark energy in fact plays a significant role in the evolution of the universe, then in all likelihood the universe will continue to expand forever.
Why is it unlikely you said shape but more detail would be appreciated
If we have a closed spherical universe the likely even like how we can observe with any ball when it rips deflated and implodes on itself. So with this sort of universe a big crunch is the most likely event.
With a curved universe we can expect the universe to rip apart as it expands ending in a big rip like a rubber band stretching to far.
But with a flat universe we can just keep rolling it out. Since there is a finite amount of matter it's like the same stuff trying to filler a bigger and bigger space. Eventually this will result in the universe experiencing heat death as the likely result.
Models of the universe based on the microwave background radiation have shown within a 2% certainty that the universe is flat. So with a flat universe the big crunch is not a likely scenario.

Actually we know it with a 0.5% margin of error:
Recent measurements (c. 2001) by a number of ground-based and balloon-based experiments, including MAT/TOCO, Boomerang, Maxima, and DASI, have shown that the brightest spots are about 1 degree across. Thus the universe was known to be flat to within about 15% accuracy prior to the WMAP results. WMAP has confirmed this result with very high accuracy and precision. We now know that the universe is flat with only a 0.5% margin of error.
