cannibalistic galaxies magnetic monsters and invisible predators although we don't know
everything about this ever-expanding universe there are some truly creepy
yet fascinating things we have discovered welcome to Factnomenal and today we will
take a look at some of the most mysterious things that have been found in the cosmos
gravity still rules it's safe to say that if we had a list of all the nightmarishly fascinating
things in the universe out there black holes would definitely make the list black holes are
regions of space-time where gravity rules the gravitational pull of a black hole is so strong
that yup you guessed it nothing not even light can escape so what could be even stranger than black
holes well try mini black holes what makes them so fascinating is that they shouldn't really exist
by definition black holes are created from the death of a star and for years astronomers and
scientists have concluded that these black holes were thought to be formed by supermassive stars
for example the smallest black hole known was at least five times the mass of the sun
many black holes are about the size of an atom and if the theories about them prove to be true
it's not just their size that will make them hard to study
astronomical black holes are so massive that their evaporation rate is negligible in contrast many
black holes are hot unimaginably hot the core of our sun is at around 15 million degrees kelvin
to get even close to the temperature of a mini black hole you would need to add another
42 zeros with this incredible temperature means is that many black holes of tiny mass evaporate
into the far far colder space around them almost infinitely fast their expected lifetime is around
1 octillionth of a nanosecond so that they pop out of existence again almost as soon as they are
created there is much debate on the formation of these many black holes while scientists continue
to gather data on them it's clear that we have only grazed the tip of the iceberg
the not-so-great attractor there seems to be something that's very very attractive
about 220 million light years away so much so that it just so happens to be pulling
everything including our whole galaxy towards itself the entire universe is expanding so it's
natural for our galaxy to be moving but this is not quite the direction it should be moving in
there exists somewhat of a gravitational anomaly that scientists and astronomers have named the
great attractor this is partly due to its stunning brightness and also its gravitational pull
the great attractor was first discovered when scientists were busy observing the norma cluster
a supercluster that is about 220 million light years away this great attractor left them
perplexed as it seemed to be tugging and pulling all of the galaxies in the region towards itself
not only that it was pulling at an extraordinary speed of 321 868 kilometers per hour
many theories now exist that dark energy is to blame for this because how else would you explain
a structure so strong and forceful that it's able to attract whole galaxies towards itself at such
a high speed others say that we may yet be missing out on certain key components of how gravity works
on a larger scale the mystery behind the great attractor is an enduring one and
may not be fully understood for a few more years shine bright like a quasar discovered
about half a century ago quasars can safely be called the brightest objects in the universe
they shine so brightly that they practically out-glow the ancient galaxies that contain them
what began as a probe into space following the static interference on translator phone lines
believed to be coming from the milky way led to the discovery of these fascinating objects which
were named quasi-stellar radio sources they later came to be known as quasars and after years of
study it was finally concluded that these distant specs were not stars most of the quasars that have
been found are still billions of light years away from us and have been found more densely in the
galaxies that have supermassive black holes and areas of large scale density of matter
since space functions like a time machine and the light we see from quasars probably took
billions of years to reach us it's possible that they existed in the early years of the galaxies
perhaps even the Milky Way had a quasar but it is now silent in 2017 the most distant quasar
j1342 plus zero 928 was discovered about 13 billion light years away
quasars emit an absurd amount of energy which could be compared to the total light of the
stars in our galaxy combined they are the most luminous and energetic objects
that have been detected in the universe and studying them although challenging
can potentially help reveal information about how galaxies have evolved over time
magnetic monsters magnetars are a special kind of neutron star which in turn are a special kind of
dead star from their name you can probably deduce that they have something to do with magnetism and
you're correct magnetars are the most ridiculously magnetic things we have ever discovered
looks like magneto's met his match to give you an idea we can start with something familiar like
the earth's magnetic field that's around one gauss and it isn't much different for the sun
a few to a few hundred gals depending on what area of the sun you're measuring an MRI is ten
thousand gals furthermore the strongest man-made magnetic fields are a few hundred thousand gauss
now to the main event a neutron star carries an incredible trillion gauss magnetic field yes
trillion as if that wasn't impressive enough enter the magnetar coming in with up to one
quadrillion gauss they are the undisputed universal strongest magnetic field champ
scientists are yet not completely sure what actually makes these magnetars so powerfully
magnetic but one thing is for sure if you get close to them the magnetic fields are strong
enough to affect your very molecular structure in other words you would most likely turn into
a human alka-seltzer and just dissolve the good news is though they don't last very long in their
magnetic monster state according to research they settle down into a neutron star after
about 10 000 years well we wish these mysterious magnetars a relaxing retirements in their new role
Eridanus Supervoid there is a massive area of nothingness in the universe which has
caused experts to scratch their heads a team of cosmologists from the university of Hawaii
first proposed it was a super void spanning 1.8 billion light years across and 3 billion light
years away from our galaxy it is found in the constellation Ericanus from where it gets its name
there are many theories surrounding this void astrophysicist Laura Mersini Houghton has said
the void could be a parallel universe that bumped into our own at some point in the past multiple
quantum physicists accept this possibility but it contradicts the laws of traditional physics
others say it could be somewhat of a universe in mass black hole
which has consumed all of the matter in its vicinity to be clear this area is not
completely empty but simply holds 20 percent less cosmic material like galaxy stars and dust
this is absolutely fascinating because voids have been thought to form due to quantum fluctuations
in the immediate aftermath of the big bang but this super void is far too large for this theory
to hold true it could quite possibly be the largest structure ever discovered in the known
universe sadly we know so little about it and it remains a profound mystery waiting to be solved
the galaxy crasher the mysterious object that passed through our solar system in
2017 has been one of the most exciting astronomical events in recent times
given the Hawaii name Omuamua meaning a message from afar arriving first it's quite possibly the
most fascinating object which was first spotted about 21 million miles away from our planet
and seemed to be heading away from the sun at a speed of 196 000 miles per hour astronomers
have said that the object had to have been nearly half a mile long and about 548 feet wide
the peculiar object had a dark red color and what seemed to be a cigar-like shape to it at first it
was designated a comet but upon further study it was found that it didn't have a comet tail
summer of the opinion that it is more of an asteroid or a large space rock which was
probably flung into space due to gravitational distortion what really adds to the intrigue
is that we are still unable to answer the fundamental questions about the origins of
and why it showed such unusual properties and behaviors scientists have even blamed
alien technology for this interstellar object because of the fact that it behaves like a comet
while other objects would have turned circles around the sun Omuamua proved to be different
it is the first ever object to fly into our solar system and back out again and although
it's no longer visible to telescopes even in space scientists continue to analyze data
to hopefully unlock more mysteries about this unique interstellar visitor the devil's triangle
one of the biggest mysteries on planet earth happens to be the bermuda triangle
you know the region lying to the western part of the north Atlantic ocean where ships
get pulled to the bottom of the ocean and airplanes seem to vanish into thin air well
there is a portion in space above the earth where we find a similar phenomena
this region has wreaked havoc on spacecrafts and anything that has entered the area
the devil's triangle in space lies somewhere above the south Atlantic stretching out between Zimbabwe
and Chile at a point where the Van Allen radiation belt is in close proximity with the earth
this area has also been nicknamed the south Atlantic anomaly or saa
it's here that the earth's magnetic field is very weak which allows for an influx of intense solar
radiation to put it simply when spacecrafts pass through this region astronauts have been known to
experience cosmic flashes and computer systems have stopped working or completely shut down
the same goes for the Hubble telescope which passes through the SAA 10 times a day spending a
good 15 percent of its time there Hubble is unable to collect astronomical data during these moments
which is not ideal but necessary to make things even more bizarre the region seems to be expanding
and it is a cause of concern as this could not only affect systems in space and on earth
but also the increased radiation could possibly lead to a higher risk of cancer
studying the different levels of radiation and the size of this portion of space will
be crucial to understanding what the future of commercial space travel would be like as well
there's no doubt that it is just one of the strangest things in space just like its earthly
counterpart so what do you think will the great attractor cause a cosmic collision of galaxies
