What They Don't Tell You About How Do Black Holes Actually Work #shorts

[00:00:00]Black holes are the ultimate cosmic mystery. Here's how they actually work.

[00:00:05]When a massive star dies, we're talking 20 times the mass of our sun, it collapses under its own gravity.

[00:00:12]The core shrinks from the size of Earth to the size of a city.

[00:00:16]All that mass packed into a point smaller than an atom. That's a stellar black hole.

[00:00:21]The event horizon is the point of no return. Cross it and you can never come back.

[00:00:27]Not because a force pushes you in, but because every direction you could possibly move leads inward.

[00:00:32]Space itself has curved so dramatically that outward simply doesn't exist anymore.

[00:00:38]Supermassive black holes sit at the center of every large galaxy.

[00:00:43]Our Milky Way has one called Sagittarius A* 4 million times the mass of the sun.

[00:00:49]It's 26,000 light-years away and completely invisible.

[00:00:53]We only know it's there because stars orbited at impossible speeds.

[00:00:58]Here's the wildest part. Black holes aren't actually black.

[00:01:02]They glow with Hawking radiation.

[00:01:05]Virtual particles that pop into existence at the event horizon.

[00:01:09]One particle falls in, the other escapes. Over an unimaginable time, the black hole slowly evaporates. The largest ones will take 10 to the 100 years to disappear. That's a Google years.

[00:01:22]The universe is 13.8 billion years old.

[00:01:25]Black holes will outlast it by a factor of 10 to the 90.
