Lets say there is a 10-20 lightyears deep cave and someone who is heavier than the rope going down with a rope attached to him -changes in gravity probably affects on such a scale so gravity is equal-. Normally, rope should be tensioned as long as person doesn’t put his feet on the ground. But what happens if the cave is that deep? Could someone on the surface feel caveman hitting the bottom faster than light could travel that distance? If he can, how can something be faster than light which isn’t obviously subatomic scale? If he can’t, isn’t tension equal everywhere on a rope?
In: Physics
Pretty much any question “is it faster than speed of light” can be answeared with “no”.
The explanation is that tension is not equal everywhere on the rope.
This is pretty much reverse of the falling slinky.
