Time - cyclical?
Name: Roberto Motta
I believe that the time is cyclic and everything happens continuously. This
explains where the energy to the Big Bang came. The universe began to
regress and exploded in one point.
You could try reading Stephen Hawking's "A Brief History of Time" which
touches on this and similar questions. Basically, it looks like the ending
of the universe that we expect from the way things are currently going, even
if the universe stops expanding and starts heading back to a single point,
will be very different from the very smooth beginning - there are a very
large variety of different "highly compressed universes" so even if the
universe returned to the same size and expanded again, things would be very
different the second time around.
