Given that the universe may have started from a singularity in a Big
Bang, and that it seems that an awful lot of the universe is going to
end up at the singularity inside a Black Hole, is it possible there is
a connection between the two?
I've seen the depiction of Space-Time as a rubber sheet with each mass
causing a distortion to it -(recall Homer Simpson looking into the
deep distortion caused by a Black Hole?) - Is it possible for the
singularity of a sufficiently massive Black Hole to distort Space-Time
to the extent where it ruptures, the singularity exploding into the
void beyond giving rise to another Big Bang and the start of another
Although the Big Bang also represents a spacetime singularity, it is
not really a black hole. Actually, the Big Bang has more of a
resemblance to the time-inverse of black holes: white holes (that may
not actually exist in nature). But the Big Bang singularity is not
really a white hole either -- there are technical differences in the
natures of their event horizons and their connection to the rest of
the universe and its constituents.
For a more detailed, and somewhat technical, explanation please see
It is also not necessarily the case that "an awful lot of the
universe is going to end up at the singularity inside a Black Hole,"
since the universe could very well be Open rather than Closed and
simply expand forever (in fact the latest evidence seems to point in
The Big Bang included all of spacetime and so does not represent a
rupturing of some space in which it is embedded (that is, there is no
"void beyond" the universe), and there is no danger of supermassive
black holes causing any sort of miniature Big Bangs although they are
responsible for the super-energetic phenomena know as quasars.
