Outer space is amazing infinite mysterious and scary but most of all it's dangerous there are
many things which could destroy humanity and even the whole universe a lot of the most dangerous
things in space are uncontrollable they're also unexpected as in we don't know when they may occur
but many of them are inevitable meaning that they definitely will happen at some point
the question is what is the most dangerous thing in our entire universe magnetar a magnetar is a
type of neutron star they have extremely powerful magnetic fields and they emit massive amounts
of high-energy electromagnetic radiation this is normally x-rays and also gamma rays
on december 27 2004 the largest cosmic explosion of all time happened the explosion was so
big it wiped out various satellites and the explosion was caused by a magnetar the most
dangerous thing in the universe magnetars possess the most powerful magnetic fields in the universe
if a magnetar got as close to earth as the moon is this would change our world
forever it would destroy the ozone layer this would mean the earth's temperature
would increase a massive amount not only that all electronics on the planet would go down
it would be like a massive emp all electricity would stop working on earth right now there
are 12 known magnetars in the milky way our galaxy but there could be more hidden in space
galaxy collisions it's quite common in space for asteroids to collide with one another and in some
rare occurrences planets collide but what about two entire galaxies colliding with each other
it sounds like it couldn't be true but this does sometimes happen in space this happens in our
universe and is known as galactic cannibalism it's called that because it's basically one
galaxy eating another when this occurs the smaller galaxy is eaten by the larger galaxy
it's kind of like a massive intergalactic game of agar.io but you may be wondering could this happen
to our galaxy the milky way the answer is yes the closest galaxy larger than the milky way is
andromeda this is 2 million light years away our neighboring galaxy is getting closer to us all the
time it's currently speeding towards our galaxy at 120 kilometers per second andromeda has twice the
mass of the milky way it's a large spiral shape much like the milky way but the unique thing is
what's in the center of andromeda at its center is a supermassive black hole which would be able
to swallow up our galaxy andromeda's supermassive black hole is 30 million times the size of our sun
right now nasa says this will occur in 3 billion years but if some kind of cosmic shift happened in
space this could happen a lot sooner quasar one of the most terrifying things in the universe is one
of the least known this is known as the quasar phenomena a quasar is a type of supermassive
black hole a quasar's mass can be millions or even billions of times the mass of our sun
much like a black hole quasars are very powerful but these have the extra power of emitting massive
jets of light these light beams receive the energy from the black hole and this is emitted through
ejecting jets the mysterious thing is right now we don't know what these flashes are even made of
but if any planet gets too close to one of these then it burns up sun death
one very scary thing about our universe which is going to happen is one day our sun will be no more
remember our sun is a star and like all stars one day it will burn up within 5 billion years the
hydrogen that fuels the sun will run out this will cause the sun to swell up and it will wipe out the
three nearest planets to it those are mercury venus and our planet earth when this happens in
around 5 billion years there will be no way to survive that is unless humans have left planet
earth for another planet for example many people like elon musk want us to move to mars but even if
earth did survive it would never be the same again it would turn from a blue and green planet to a
red planet like mars the sun gives us life right now but it can also take that life away supernova
stars look absolutely amazing but while they do look mesmerizing they can also be very dangerous
stars are pretty heavy a star's mass is supported by its energy which comes from its nuclear fuel
but if this runs out then these stars can explode this creates what's known as a supernova these
supernovas can form planets but just as they can create planets they can also destroy them
too right now in our galaxy there are two known stars which could explode into supernovas these
potentially could destroy the earth and we don't know when they may explode black hole one of the
most dangerous events in the universe are black holes they are very ghostly but also very damaging
at the center of black holes gravity is so intense that nothing can escape its grip this means stars
planets and anything else could be pulled into the black hole not even light is safe in our
universe there are thousands of black holes in our universe there are thousands of black holes
but the scary part is we can't see most of them this means if a black hole appeared in our orbit
it would be very bad earth could be swallowed up or space could be moved around so much that earth
would be thrown into a void but now it's time to make your voice heard comment down below which is
the most scary thing in the universe if you want some more amazing videos then check out my second
