Join Brian Cox as he traces the origins of one of science’s most fascinating concepts: the black hole. 🕳️✨ Long before Einstein, scientists were already thinking about how gravity works by calculating escape velocity — the speed needed to break free from a planet or star’s pull. They asked a simple but profound question: what if the gravity is so strong that not even light can escape? From these early musings, the idea of the black hole was born. With his signature clarity and wonder, Brian explains how a thought experiment centuries ago paved the way for one of the most important discoveries in modern astrophysics.

I didn't realize an escape velocity needed can be faster than the speed of light. I guess that's why they call it a black hole? Coz nothing can go faster than the speed of light, right? Goddamn I'm too stupid to understand all this stuff but goddamn if I won't stop being fascinated with astrophysics

8 sounds like a small number, but 8 miles per second = 28,800 miles per hour. Imagine if you were doing 100 mph in your car, if you had a ramp at the correct angle, you would have to travel 288 times faster just to escape earth.

Laplace was a very distinguished mathematician, the other I did not know about.

Thinking light has mass, which would equate to something escaping the gravitational pull of the sun would mean there could be a limit to a stars ability to send light away from the star when a star is extremely large. This could mean there are extremely large stars without producing observable light, but are not black holes.

Wow I like this way of thinking about it

If you need bigger than the speed of light , then the light will not escape either .

So gravity within the black hole is pulling faster than the speed of light in order to pull light in and keep it from escaping.

Very interesting
I am also interested to know why a better picture of Rev John Mitchell could not have been used?
Or why La Place is “great” and Rev John Mitchell is just “Mitchell”.
It seems to me unsurprising that a mathematician should have been thinking in this way, but a clergyman? Surely the clergyman was also great?

Yes, but it was another German, Karl Schwartzschield, who came up with the idea.

What if black holes are linked to the big bang? After all the matter and energy entering a Black hole must go somewhere, If it condenses to a certain point what if they just... Burst, Exploding out and returning that matter and energy to the universe, I think the confusing part of that theory is that means matter and energy had to exist beforehand...

But how can very heavy stars then emit light?

miles in 2025? come on!

After these 10-11 months I’ve been thru I really just wanna be left alone. I’m tired of the games that are played everyday!!! All this magnificent stuff and shit goes in circles. Crazy man

I am SHOCKED, Brian actually said 8 miles/second instead of 11 kilometers/second.
