Hawking's theories on the Big Bang

The theory about a Big bang implosion at the end of the expansion of the
universe .... Is that still a considered possibility? On my personal
observance of an albeit simple "everything that processes poops" type of
theory, a constant consumption and expansion (in my opnion) would be
more apt to be. If there is a more massive source of gravity in the
universe that would slow or stop the expansion then it seems everything
would slow and finally recede (and does so on a small scale). But upon
my observances I tend to believe that the universe is more like a match
at striking. Sparks fly outward and the flame grows and expands as long
as the fuel for the flame exists.
