Black holes
What’s on the other side of a black hole?
A super nova explosion
To understand this question, you must first understand what a
black hole is. Black holes are when a star undergoes a supernova explosion
and collapses in on itself. Once it does that, nothing can escape it
not even light hence the reason it’s called a black hole.
What is a black hole?
Black holes
Black holes are one of the weirdest things in deep space. An area with a
black hole within its radius is doomed to be sucked into its strong
gravitational field. If light, which is the fastest thing we know of, travels
at 300,000 kilometres per second, it cannot escape the gravitational pulls
of a black hole. So far nothing human scientists have discovered can.
Black holes aren’t really holes and in reality are not empty. They’re filled
with tons of debris and junk from deep space. Black holes are in fact
invisible and can only be seen by scientists by using special tools on their
telescopes.
Black holes can range in size the smallest being as small as an atom but
with the mass of a large mountain! Other black holes are called Stellar
and can have 20 times the mass of the sun! (That’s pretty big!) The
largest black holes are called Supermassive and these black holes have
more mass than 1 million suns put together!
Scientists have proved that at the centre of every big galaxy is a
Supermassive black hole. The black hole at the centre of our galaxy (the
Milky Way) is a black hole called Sagittarius A.
What’s on the other side of a black
hole?

Some people believe that on the other side of a black hole is another
universe and that humans could use them to hop from one universe to
another. Others believe that on the other side of a black hole is nothing
and that once everything has been sucked into the black hole, it will eject
everything and just disperse. Whilst some say that simply the only thing
on the other side of a black hole is death.
The scientists studying what they think are black holes could actually be
studying wormholes leading to another universe and some actually believe
that that is what they are studying.
What would happen if you were sucked into a
black hole?
Some people believe that if you were sucked through a black hole
you would end up in another universe and would never be able
to return. Unless you found another black hole leading to our
universe and survived it, which is highly unlikely.
Spagettifacation
Scientists believe that the only way to survive a black hole is to be in a
box so strong it can withstand the gravitational pulls of the black hole.
If you do fall into a black hole the forces pulling at you’re feet are so
strong your body would be stretched so much to would be ripped to pieces
this is called spaghettification. You would become a long line of atoms
flowing down the black hole.
Conclusion
Black holes are one thing that still remains a mystery to the scientists
back down on Earth. Black holes have many big questions that may never
be answered. So answer for yourself what do you think is on the other
side of a black hole?
Glossary:
Super nova explosion = Supernova explosions happen when a star
nears the end of its life time. When its nuclear fuel runs out and is no
longer supported by the release of the nuclear fuel.
Spagettifacation = Spagettifacation is where in this case people or
things get stretched into oval like shapes in a strong gravitational pull
such as a black hole.
Gravitational pulls= Black holes have strong gravitational pulls which
mean they pull everything towards it including light and matter!
Atoms= Atoms are small particles of the air around us and can only be
seen through a microscope.
Wormholes= A wormhole is any structure connecting two regions or
areas otherwise distant or unrelated.
