The Greatest Mysteries of the Universe - Documentary
Δημοσιεύτηκε στις 5 Ιουν 2017
The
scientists have discovered a ‘supervoid’ in space, a peculiar empty
section of space which is missing roughly 10,000 galaxies. This empty
space, which is thought to be the largest known structure ever
discovered in the universe, is baffling experts.
Scientists are
unclear about what this desolate space is. However, this isn’t the first
mystery of outer space that has left those in the know scratching their
heads.
Where do galaxies come from?
Astronomers haven’t
yet settled the question on where stars and planet come from. It is
believed galaxies started to form about the same time roughly 13 billion
years ago. We know they aren’t just positioned randomly across the
universe, but instead form clusters. The Big Bang theory says the
universe expanded following a state of very high density. A separate
theory suggests small gas clouds merged as a result of gravity and then
condensed to give shape to galaxies.
Is there Earth-like life elsewhere?
Are
we the only planet with life as we know it? Or are there many more
planets like Earth out there in the universe? Scientists still don’t
know for sure but planets with similar characteristics to ours have been
found. Planet GJ 581g, for instance, is thought to have liquid water on
its surface just like Earth. Does it have life too?
Dark matter mystery
It
sounds like something out of a Star Wars movie but it is one of the
greatest puzzles in the universe. In the 1990s scientists discovered the
universe is expanding and they gave this process the name of dark
matter. Thought to make up roughly 70 per cent of the energy density of
the universe, scientists are still unsure on how this mysterious energy
works.
Is there life much closer than we think?
Sometime
mysteries come in the shape of conspiracy theories too. Scientists keep
debating the possibility of life in galaxies light years away from
Earth. However, some have argued that the moon is filled with ancient
ruins and buildings, which would prove there was life (or is there now?)
on the moon. Who knows?
Where are all the white holes?
Much
hullabaloo has been made of dark energy or empty voids, but there are
such things called white holes. Albert Einstein, through maths, was able
to prove the existence of holes that seem to expel large quantities of
matter from what looks like not much. However, scientists have not been
able to locate such an object in the universe. The reverse of a black
hole, a white hole can’t be entered from the outside. But what exactly
is it?
