What Happens If You Destroy A Black Hole?

posted by Jason Kottke Sep 21, 2023

Here's a fun thought experiment: can you destroy a black hole? Nuclear weapons probably won't work but what about antimatter? Or anti black holes? In this video, Kurzgesagt explores the possibilities and impossibilities. This part baked my noodle (in a good way):

Contrary to widespread belief, the singularity of a black hole is not really "at its center". It's in the future of whatever crosses the horizon. Black holes warp the universe so drastically that, at the event horizon, space and time switch their roles. Once you cross it, falling towards the center means going towards the future. That's why you cannot escape: Stopping your fall and turning back would be just as impossible as stopping time and traveling to the past. So the singularity is actually in your future, not "in front of you". And just like you can't see your own future, you won't see the singularity until you hit it.
