The universe is filled with
galaxies. The
velocity of the rotation of a spiral galaxy, for instance, depends on
the amount of mass contained in them. The outer part of our own Milky Way
rotates much faster than the core. The rotation velocity is not consistent
with the mass. Scientists are sure that there should be 10 times more matter.
So, where are the rest? We cannot see it. Something is missing. This
‘something’ is a big one. As time goes by, we came to know that matter in the universe only
make up about 4%. The rest are 23% dark matter and 73% dark energy.
Can the universe be created out of
nothing? Let's see what Prof.Michio Kaku says :
1.If you calculate the total matter in
the universe it is positive.
2.If you calculate the total energy of
the universe it is negative, because of gravity. Gravity is negative.
3.So what happens when you add these two
together? Zero.
4.So it takes no energy to create a
universe
No energy. ‘Nothing’ is needed to create
a universe. Remember the bubble theory. When ‘nothing’ is unstable, bubble forms,
and when either the bubble divides, or come into contact, as a result, a new
bubble (universe) is formed.
In String Theory, this is believed to be what the big bang is. When we thought that
the empty space is ‘nothing’, we discovered that it has something. It is filled
with dark energy. This dark energy is the energy of ‘nothing’. To understand
the creation of the universe, we must understand dark energy. It is very
crucial to understand what ‘nothing’ really is.
This is just like if you ask a
troubled looking girl if there is anything wrong with her. She will probably
say, "Nothing". Well, nothing could actually mean something; most
likely something big is going on, usually. Maybe it holds true for this
‘nothing’ in the theory that we are trying to understand. Is dark matter,
the matter of nothing too?
