From the viewpoint of an observer in the orbiting rocket, what happens to time on the other rocket as it falls toward the event horizon of the black hole?

a) time runs increasingly faster as the rocket approaches the black hole.
b) time runs increasingly slower as the rocket approaches the black hole.
c) time is always the same on both rockets.

C since the black hole has no mass therefore it has no pulling gravity!

I’m pretty sure it’s C! Sorry if I’m wrong! :)

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
