How Close Can You Orbit A Black Hole?

Black holes are weird. In particular the orbits as you get close don't behave like Keplerian orbits in Newtonian physics, which leads to many misunderstandings about how close you could get to a black hole. Many sci--fi writers make the mistake of presuming that the point of no return is the Event Horizon, when in fact there are limits even further out.

"if there is enough interest"

As if you ever doubted what the audience would respond with.

[KingNefiiria]

I'd be interested, if you have the time and energy.

[westonthomas]

I have an interest in the rotating black hole maths!

[SpecialEDy]

I have a question. If two singularities spiraled inwards towards collision, like the events LIGO is built to detect, is a trajectory possible that could bring you inside the event horizon and back out through the legrange point? It seems the event horizons would both expand in every direction as the singularities approached each other, except a legrange point between. There must be some point before the event horizons coalesced with a bubble in between, where there is a corridor in between.

ITS *NOT* SCHWARZ *CHILD*
ITS SCHWARZ SCHILD
german for black shield
lmao at 1:05 (the next one not understanding its about spelling not pronunciation will be *pointed at*)

Schwarz child : black kid
Schwarz Schild: Black shield

I am very interested in an episode about rotating black holes

[tak]

Please continue! I love relativity hypotheses, and discussions about black holes. This stuff fascinates me so.

I think the name you were looking for is SchwarzSchild, not SchwarzChild...

[whoeveriamiam]

finally somebody who wants to start talking about rotating black holes on youtube?
I've seen so many videos about black holes and they all end with "but rotating black holes are different, goodbye"

[FallenPhoenix]

Nooo this video is too short.Get your brain unblown right now mister.

[toryunaminosaki]

still, even at 5x SR...it'd be creepy as hell to look out your window into a complete void, the maw of this celestial monster...
the thought of it makes me shudder a bit

[daniellassander]

I would love a video on rotating black holes also black holes with a non zero electric charge.

[NessHX]

1) its the second time you promise to make a vid about rotating black holes if enough people are interested - I'm interested!
2) if falling down from infinity makes you land on a stable orbit - does that make the system break time symmetry?
3) the big thing about general relativity orbits is that the runge-lenz vector is not conserved - this is something worth mentioning

[ALegitimateYoutuber]

i wonder is there a maximum size that a black hole can be? Like a point where it no longer is a black hole or fails to maintain itself.

[Electroblud]

Yes please rotating black holes. And charged ones if you're already at it. I want MOAR KNOWLEDGE! ;D

[gabrielsabode]

Great job making a seemingly boring physics lesson enjoyable! i love your content scott. Keep teaching the current generation.
