Scientists Reveal What's Actually Inside a Black Hole

Join us in today's epic new video as we journey through the cosmos to understand what black holes are, how they form, and why they could lead to the destruction of everything as we know it.

Scientists: We have no idea what's inside a black hole.

If you can find a black hole to fall in to, then you complete the first level and progress on to level 2.

3:15 Light travels at 186, 282 miles per SECOND, not per hour. And light doesn't always travel at that speed. That's the speed in a vacuum. There's a lot of things that can change its velocity, water for one instance.

Imagine living in the 17th century and trying to explain black holes and your evidence is "Trust me bro, i cant show my work"

[rgfdgy]

My all time favorite topic. I don't find anything more fascinating than space and the black hole

[geordiedog]

Best way to view the event horizon is that at that point all directions lead into the black hole. So, whatever way you try to go you are heading into the black hole. Also, “singularity” in science usually means ‘we don’t know!’

Nothing more fascinating and crazy than space, planets and the universe.. can watch it for hours

"Let's say you were a small insect..."

Immediately proceeds to show us an arachnid 😂

"Where is 'factual inside of black hole' timestamp?" Dumbledore asked calmly

[Fomites]

This is the best explanation of black holes I have encountered. Thank you 🙂

So we are pretty much on a space ship with no controls hoping for the best.

Title: "Scientists Reveal What's Actually Inside a Black Hole"

In the actual video content at 27:20: A black hole with a giant interrogation mark is presented: "because we know a decent amount of what goes on around a black hole but absolutely nothing about what happens inside one."

[JosephWiner-ffjq]

Absolutely one of your best videos yet! Very well done 😊
Something kind of neat with gravitational lensing- light from a galaxy can diverge in different directions when it passes through gravity wells. Because some of the light takes longer to reach us, some stars and galaxies appear in our sky in more than one place.
Science was able to predict where a supernova would be in the future after observing it first.
Or something like that, but pretty neat tid bit!

we need a part 2 of this, I"m hooked.

[JustSumChillAlien]

Light is information. And information is never lost, always found as it's always returns to source. It maybe gone in this universe, but definitely not lost in another.

[jayayerson]

Except... the event horizon isn't necessarily the same place you would undergo spaghettification.
For larger black holes, it's inside the event horizon, meaning an outside observer will never see you die.

[StephenMiller]

I did fall into a black hole. My ex. Lol

[zogar]

The video didn't mention a very important way of super massive black holes forming. Direct collapse. This step is thought to be needed to get to the black holes we see now. As while all the ways the video listed do cause black holes to grow, there hasn't been enough time for any of them to actually grow to super massive status through just those means.

But with direct collapse, you start with a much bigger black hole, possible 10s of thousands of solar masses right away, maybe more. So it makes it a lot easier to get to the sizes we see in the time they have to get there.

[kattphloxworthych]

In case it hasn't been said already, light doesn't travel at 186, 282 miles per hour. It travels at 186, 282 miles per SECOND.

[alexrudolf]

At 3:18 there is a mistake and the mph should be miles per second in regards to the speed of light in a vacuum.
