The last sentence is not true.

The centripetal acceleration and the acceleration due to the black holes gravity do not cancel in a stable circular orbit, they are the same thing. And I don't mean they are equal, I mean there is just one interaction - the acceleration caused by gravity, and it causes the acceleration we can determine from the motion of the object, which we call the centripetal acceleration.

Does an object in a stable orbit around a black hole experience time dilation relative to a region far away? [View all] Shermann Jan 2024 OP

I thought this was a question about Trump lawyers nt Stardust Mirror Jan 2024 #1

Yeah they definitely are looking for ways to slow down time! Shermann Jan 2024 #2

Planning a little intergalactic trip and want to make it seem longer or shorter? marble falls Jan 2024 #3

Yes. Salviati Jan 2024 #4

Right, but can the effects be canceled out? Shermann Jan 2024 #10

They aren't canceled Salviati Jan 2024 #11

OK so gravitational field strength and gravitational potential are two separate things Shermann Jan 2024 #14

Right, they're different - but related. Salviati Jan 2024 #16

Oh I got them reversed! Oh well. Shermann Jan 2024 #22

I feel that time changes when I stand up. Arne Jan 2024 #5

Does an object ... experience time dilation? sanatanadharma Jan 2024 #6

"Experience" means simply encounter or undergo in this context. Shermann Jan 2024 #7

I "googled" this through Duck Duck Go: stable orbits around black holes and time dilution Backseat Driver Jan 2024 #8

Just for funzies I posed the question to Microsoft Copilot Shermann Jan 2024 #9

Have to be careful about trusting AI Salviati Jan 2024 #12

Yeah Copilot got part of that from the OP! Shermann Jan 2024 #13

What about gravitational tides? Jeebo Jan 2024 #15

Some really weird stuff happens around black holes - even outside of the event horizon. Salviati Jan 2024 #17

Again, pardon my ignorance, but ... Jeebo Jan 2024 #18

By radius here... Salviati Jan 2024 #20

Could you help me find something? Jeebo Jan 2024 #21

That doesn't give a whole lot to go on, and it's not ringing any bells. Salviati Jan 2024 #23

The last time I orbited a black hole, time just stood still, just like it does on the church pew on Sunday morning. Chainfire Jan 2024 #19
