It's called "The Big Crunch", Art, and is the theory
to which I personally ascribe. I'm trying to live
long enough to see it happen. :-)

I believe the universal expansion from the Big Bang
will someday reverse itself and collapse back into
the singularity from which it came. It's called
"The Oscillating Universe", a book I read half a
century ago about the time I graduated from Texas A&M.
