| I want to ask about the theory of the multiverse
system. If the science community feels it exists,
how ? If not, what could be the possible boundary
of our known universe? and what is the
relationship between a multiverse system and
quantum mechanics, with emphasis on linear and 3D
time frame, random events, etc? |
Answer 1:
Multiverses are predicted by a number of
theories of quantum mechanics, particularly those
dealing with gravitation. Most of these theories,
if I understand them correctly not being a
physicist myself, are based on the underlying
symmetry of physics within our universe being
complimented by the existence of other universes
in a multiverse. I think I can confidently say
that none of these theories have been tested yet,
so what kind of a multiverse, if any, exists, is
at the moment purely a subject of conjecture.
The universe that we live in, from what we can
tell of it, is infinite: there is no large-scale
structure to the cosmos of a sort that would
indicate that the universe has a center or an
edge. This could mean that the universe really is
infinite, or it could mean that the scale of the
true structure of the universe is just too large
for our limited observations of it to be able to
see; because the universe is only 13.7 billion
years old, we can only see 13.7 billion light
years into space and time, since that's the amount
of time that light has had to travel.
