c o u ld / m ust be many universes, which are in the
same space and time as our universe. These
universes
m ay/m u st have their own history
and laws of physics. This is not a fact for
the moment, but some day it
m ay /m u s t be
possible to travel to the other universe to
your favourite singer’s concert.
4) How did the universe begin? The uni
verse includes everything that we know,
including time. But what was there before
the beginning of the universe? Different
studies talk about the “ Big Bang” , which
started the universe from a single point. It
happened around 13.8 billion years ago.
But it did not simply appear from nothing.
There was the Big Bang not in space but of
space. The Big Bang created the universe.
What started the Big Bang? Where did all
the energy and matter come from?
5) There are several opinions about how
the universe will die. There are several ways.
According to the first idea, the universe will
continue growing and, in the end, it will
become a cloud of thin dust. Another way is
that the universe will fall back into a single
point, which may start another big bang. In
general, nothing will happen to the universe
for more than
20
billion years from now.
