# Can an object be broken if it's between two gravitational wells?

Think about this: take a human, tie each arm with a rope to a car and speed up the cars. The person would die dismembered because his arms would be plucked from his body.

My question is if it's possible to do the same with gravity. For example: take a human, put in each side a massive object (e.g: black hole, or a sun) and wait. What will happend? (don't take in note vaccum, heat or radiation...)

The thing that I am tring to ask is if gravity is possisble to cancel with two gravity wells or is that is just an illusion (the object doesn't move because two vectos are doing the same amount of force in opossite directions). I mean:

• Both gravity wells will cancel each other. So the human won't nottice nothing. Or;
• Gravity wells won't cancel. Both wells would pull the human so he will be splited in two (and die dismembered).

In case the first is true, would "specials things" caused by gravity (like slowdown time, warp the space and other kind things that I don't know) still happen or they will be cancel?

• You don't even need two gravity wells: look up 'Roche limit'

• @tfb. 1) I am not sure but I thing Roche limit can only be applied in object which use their own gravity to stay together (e.g: planet). But a person doesn't use gravity, it use the strenght of the materials which is made. 2) I am not talking about how to broke an object, I want to know if the effects produced by gravity (like the pull) can be cancel with another one in the opossite direction or in real both effect are applied at the same time.

• Yes, the Roche limit applies to gravitationally-bound objects. Objects bound by stronger forces would need to get closer, but they too will be disrupted: a good example of this is the 'spaghettification' which occurs near the horizons of (sufficiently small) black holes.
