For centuries the search of this unseen matter has been on.
The human mind is always attracted to many significant questions about their existence
that might be plausibly being answered in the near future.
Roughly 70% of the universe is made of dark energy and about 20% Dark matter.
Dark matter is an aspect of the universe we still don’t
fully understand. We have lots of evidence pointing to its existence.
Scientists estimate that dark matter amount up to 95 percent
of all matter and energy in the observable universe. And might be solvable in
the near future like what existed before the big bang? Or what is time? The Death of an early star. One of the first
stars in the universe explodes, bursting through its halo of invisible dark
matter and speeding carbon, oxygen and other elements The stars might never
have formed and certainly not so soon – 100 millions years after the big bang
without gravitational force generated by abundant dark matter. Its nature is uncertain. Dark matter act like cosmic glue.
Little is known about the dark matter and dark energy except
for their influence on things we perceive. Dark matter interacts
gravitationally with observable matter. Cosmologists have noted that galaxies
contain much stronger gravitational fields than could have been generated by
the stars that are seen. Dark matter interacts little if at all with the
visible elements of the universe.
Normally, it is assumed that dark matter doesn't interact
with light directly at all. This means we can see its gravitational effects.
Dark energy is even more mysterious, it is what causes the
rate of cosmic expansion to be increasing rather than decreasing. If dark
energy is the property of space and time, a quantum theory of vacuum may be
required before researchers make sense of it. Such an account is often called
quantum theory of gravity, since Einstein’s general relativity depicts
gravitation as dues to curvature of space.
Besides giving the universe structure, dark matter may play a role in its fate. the universe is continuing to expand but will it expand forever? Gravity will ultimately determine the fate of expansion, and gravity is dependent upon the mass of the universe.
