hey geeks you are watching closed book
we provide information about mysterious
facts latest technologies and
inventions. When you look at a night sky
what excites you the most? Did you ever
imagine about stars, galaxies, black holes,
supernovae, etc. So let us start
our first video. Can you ever imagine if
I say that the universe we know is just
5%? Yes, but what about remaining 95% of
universe? Here comes an interesting
unsolved mystery of the universe which
is "Dark Matter". According to the
predictions of astronomers and
cosmologists 68% of universe is made up
of dark energy and the remaining 27% is
dark matter. As this particular matter
doesn't react with light it is named
"dark". This interacts with gravity proving
its existence.
Essentially the gravitational force
exerted by galaxies and clusters is
insufficient to hold them. There got to
be some additional mass to create extra
gravity. Without dark matter it is not
possible. If not, the stars would likely
to be scattered throughout the universe,
galaxies including the Milky Way and
therefore we would not probably exist.
According to the theories after the Big
Bang universe started to expand.
The scientists thought the expansion of
universe is very slow but, an image of
supernova which has been captured by
Hubble Space Telescope proved that the
predictions have gone wrong and the
expansion is accelerating. Some
mysterious energy is driving this rapid
expansion which is "dark energy". We will
discuss it in our later videos. According
to the assumptions dark matter is made
up of dark particle
which is an unknown subatomic particle.
Misconceptions about dark matter.
Scientists thought it is an antimatter
but when matter and antimatter react
the produce a unique gamma rays which
is not yet detected.
Is it a black hole? It is not a black
hole because we can observe the bending
of light
around the black holes. Thy are are not huge
clouds of normal matter without a
stay because normal matter emits
particles which can be detected. Many
experiments like LZ, Fermi gamma-ray
telescope, Atlas and universe mapping are
going till date to detect the properties of
dark matter. If we can discover the
properties of dark matter it will lead
to the revolution in the field of
science in a rapid manner. Although it is
left as the biggest unsolved mystery of
the universe. So guys here is some
informative stuff about dark matter. Hope
