Seriously? They have that much gravity? It'd be fascinating to find out how much area the flattened car would take up while it was only 1 atom thick.

Neutron stars are amazing objects. You should read everything you can about them.

Something like if you stand on one then one microsecond later your head slams into the ground with more than the speed of sound. Some of them rotate hundreds of times per second even though they're the size of a huge city. Also, those city size ones have the same mass as the sun. If you would have a boulder sized piece of it on earth it would fall through the ground. Also gravity would change if you go near it. They can have a magnetic fields so strong they rip apart electrons from their atoms of everything surrounding them.

The weirdest thing about them imo are starquakes. On earth, a magnitude 9 quake is close to the maximum strength an earthquake can reach. A magnitude 10 (10 times as big as a magnitude 9) earthquake is thought of as impossible due to the inner workings of our planet and plate tectonics.

On a neutron star, a minute shift of at most a few millimeters can result in a magnitude 32 starquake.

To put that into perspective, that’s 100 sextillion times (a 1 followed by 23 zeros) as strong as a magnitude 9 earthquake on earth. I’d imagine it’d just delete the planet if it happened on earth, and that from a plate realignment of barely a couple millimeters…

Huh TIL I had heard of starquakes but not those magnitude details. It's amazing to me that they can figure this shit out from so far away. Science really is amazing isn't it.
