if every possibility is played out
across this huge multiverse well it
makes our universe just a sheer accident
I'm dr. Stuart Clark I'm an astronomer
and I'm the author of the unknown
universe now the multiverse is something
that has come at astronomers and
physicists from a number of different
angles it seems that there are a number
of problems in physics and astronomy
that could be solved if there were not
just this universe but an infinite
number of other universes so one of
those things is whenever a quantum
particle changes its state there's
nothing in our laws of physics that
direct it to change that state in one
particular way or another so how does it
choose to do that well if there's a
multiverse then every possibility is
played out so it becomes understandable
in that way and also when the
astronomers look out into space I mean
they see as far as they possibly can but
what's beyond that are there other
realms out there as well other universes
and then when we start to get into
theories to try to join gravity our
understanding of gravity with the
understanding of the other forces of
nature then we're led to things like
string theory and they postulate
different dimensions of existence again
natural places to find other universes
and so in all these different ways there
could be multiple universes now that
sounds great
but of course if every possibility is
played out across this huge multiverse
well it makes our universe just a sheer
accident we happen to be in it just
because it happens to be the one when
all the conditions are right for life so
there's nothing there's nothing written
in the laws of physics which direct us
towards this orderly universe around us
I think for me I would prefer it if
there wasn't a multiverse if the
universe that we see around us today is
all that there actually is and that
Spurs us on to find the
or the meaning if you like in the laws
of physics the reason why the university
is just this way and no different but of
course the universe doesn't have to care
what I think or want to it it will just
do what it does
