Black holes are a deep dark mystery.
Literally.
Our galaxy alone is thought to contain anywhere between 10 million to a billion of them.
We know they have the ability to destroy planets, maybe even solar systems, but why exactly?
What is going on in there?
Hello and welcome back to Life's Biggest Questions, the channel that wants to answer
everything and anything but actually, curiosity didn't kill the cat… that's just a thing
people say to keep you in your place.
Knowledge is power, but is there anything more powerful than a black hole?
Seemless.
I am your host Rebecca Felgate and today I am asking What is inside of a black hole?
Okay but I also really quickly want to say that each and everytime I host these videos
Muse's Supermassive Black Hole dances through my head all day….anyone else know that song…just
me?
*editors play clip.*
Right – before we get into this video, I want to ask you what YOU think is inside a
black hole?
While you are down there leaving a comment, why don't you hit that thumbs up button
and share this video with a person that needs to see the inside of a black hole today.
Also if you want to connect with the team that went into making this video, there are
links to our socials in the description box.
Okay, black holes.
So black holes were first discussed in the 18th century, but it was David Finkelstein's
1958 publication that established them as a region of space from which nothing can escape.
Fast forward 60 years and we now know a little more about black holes but, excuse the very
intentional pun, we are still very much in the dark.
In fact, one of the biggest goals in astrophysics is to understand and observe what happens
in a black hole.
What we do know is that black holes are areas of space and time that exhibit such strong
gravitational pulls on all things, from particles to radiation and even light, that nothing
can escape it.
This has lead scientists to realise that black holes are very, very, very dense.
There are two types of observable black hole – Supermassive and Stellar Mass…although
there may well be a third; miniature black holes.
At the moment we are going to talk about the two observables.
Supermassive black holes have the mass of many millions, maybe even billions, of stars
and stellar mass black holes are still dense, but on a much smaller scale.
These black holes comes from the gravitational collapse of a huge star.
Our sun, would need to be around 25 times its size to create a supernova and then a
black hole.
Stellar mass black holes can be anywhere from 10 times as dense as our sun.
The nearest one to earth is thought to be up to 12 times the mass of our sun.
Named Monocerotis, it is 3,000 lightyears away…that's 18 trillion miles….
It would take the fastest rocket we have on earth hundreds of thousands of years to reach
it…so, probing is basically at this point not an option….we are doing our best when
it comes to telescopes; Hubble can actually observe light from 13.2 billion lightyears…so
we can see them…we just can't travel to get a better look.
So, as you may have gathered, because of the limitations of current technology, we can
only observe what is going on surrounding a black hole, rather than knowing exactly
what is inside – however our observations give us a clue.
It seems that blackholes are so, so dense that they cause the laws of physics as we
know to break down.
The way gravity works is that objects of a lower mass are drawn to objects of a higher
mass.
Black holes have extremely high masses and they start to break down things that approach
it.
It can tear planets and even stars apart.
The black hole is kind of like a drain in slow motion, Particles that have been torn
from what they previously are, as well as radiation and light, swirl in that hole until
they fall in.
This swirl is called the event horizon…which is very much the point of no return – from
this point you can't see any light as no light can escape.
We have never seen beyond the event horizon, all we see is what is not there – darkness…a
black hole.
We do have some pretty educated theories as to what could be inside, though.
Well, for starters, it is hot.
The event horizon may as well be called the ring of fire - as the material gets consumed
by the black hole, friction heats it up to billions of degrees, producing lots of radiation,
and outflows of energy and charged particles.
Beyond that, it is thought that the black hole is like a funnel, leading down to a small,
very very very dense place just one atom wide, as matter is destroyed and sucked into the
hole, it is stretched out in a process scientist call spaghettification.
The thing is…. even if we could get up close to a black hole – anything or anybody we
have on earth would be destroyed and sucked in by it – so couldn't report back exactly
what is inside.
It is a paradox.
Although, the paradox in theory could be broken if something could travel fast enough through
it – perhaps faster than the speed of light.
It's just a theory, but some cosmologists are pretty keen on it.
Even if we could travel that fast – I am not sure I would want to be the one testing
it out.
Toward the end of his life, Professor Stephen Hawking was working on a theory of multiverses.
He alluded to the possibility of a black hole spilling its matter out into a separate place….a
new universe, maybe.
He said The hole would need to be large and if it was rotating it might have a passage
to another universe.
But you couldn't come back to our universe."
So…what is in a black hole….If it sounds like I haven't really answered the question
so much as I have discussed black holes in general, you would be right.
As of yet, we simply do not know what is inside a black hole, but as we discuss them and study
them.
The answer may be closer on the horizon than we think, too.
Scientists have created a machine called the Large Hadron Collider – it is a particle
smasher that they want to use to simulate some of the things that happened at the beginning
of the universe.
Not only could this machine shed more light on the big bang – some think it could create
miniature black holes.
This may be a touch far fetched, but if it could…then perhaps we would be able to answer
this question once and for all.
So guys, what do you think is in a black hole?
Let me know in the comments section down below.
Also why don't you click that thumbs up button to and the notification bell to be
the first to hear big answers.
My head feels like it has been sucked into a black hole so I need to get out of here.
Thanks for listening.
I am your host Rebecca Felgate, I'll catch you in the next video, but until then – stay
curious, stay alert and never ever stop questioning.
