Question:
Do you believe that the ''big crunch'' theory will actually happen?
Replies:
I am not sure exactly what you mean. If you mean is it possible
that some day the universe will collapse back onto itself, then
that will depend on whether there is enough mass in the universe
to keep it together. At the moment there isn't enough mass that
has been seen or inferred, so the answer of today would be that
the universe will probably never collapse back on itself. But,
we could still find the extra matter, maybe. Many are looking for
it.
