(Science Magazine)   Ya see Timmy, when a massive star reaches the end of its life, it can explode as a supernova - but if it doesn't believe in itself it just turns into a black hole   (sciencemag.org) divider line

Don't truly stellar ones do both?

I just watched a video yesterday with an interview of an astrophysicist.

I learned that black holes evaporate over very long periods of time thereby breaking the "information is never lost" rule of physics.

Mind blown.

I now doubt that any of this is actually happening.

Learning that suns go supernova filled me with existential dread for years back when I was in kindergarten or first grade. Then black holes continued that. Basically left me with the certainty that we all could die at any moment from some unknown space cause and the chance of it happening only rose with time.

Theoretically. The effect would only be observable in microscopic ones which we've never detected.

They didn't, oddly enough.  But the Jetsons episode where Elroy went around the black bowl and came back horribly aged but still the same size scared the crap out of me.

Black holes are created by a lack of support.

Support your local stellar object.

Don't judge ;)

My understanding is that any large enough (>8 solar masses) star will go supernova, and above another threshold which I forget, it will become a black hole after going supernova. But it seems in this case it started to go supernova, but just kinda stopped, and scientists think it's because it became a black hole too quickly to allow the usual supernova process to run its course.

Species of mammals average about a million years before they go extinct. We've had a good run, time to die.
