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.

Luka Modric wife: What is her name? How long have they been married? - Duration: 4:02.

 The midfielder has led Croatia to the World Cup final and also won the Champions League with Real Madrid this year

 He joins Cristiano Ronaldo and Mohamed Salah in the final three of the Best FIFA Men's Player award

 Modric will be looking to add to his personal collection of awards too. He was crowned player of the tournament at the World Cup, winning the Golden Ball award

 He was presented the award by Russian president Vladimir Putin after defeat in the final against France

 Modric was also named UEFA Men's Player of the Year by beating Ronaldo, something he'll be looking to repeat

Luka Modric wife - who is she? Modric married girlfriend Vanja Bosnic in Zagreb in May 2010

 He had been dating her for four years before they tied the knot. They got married in the Croatian capital Zagreb at a private ceremony
