Gravitation, 2 objects of same properties

In summary, gravity works by warping space around objects, causing other objects to fall towards the object with the larger warp. When two identical objects with the same mass and velocity approach each other, they will either combine into one body or orbit around their center of mass. Unlike tectonic plates, space is more malleable and the curvatures will merge together. However, this analogy should not be overextended as it does not include time, the third dimension, and space can bend in more ways without breaking. As objects get infinitely far away, the warping of space approaches Minkowski space.

Okay so I'm under the understanding that the way gravitation works is that each object warps the space around itself, and essentially objects caught in the warping are "falling" towards the object with the bigger warp in the center.

So my question is, how do objects that are complete clones of each other, that have the same mass and everything, fall towards each other? Wouldn't the space warps almost make a "mountain" of space between the two, like tectonic plates moving towards each other, and the objects would actually end up repulsing each other? Or as they near each other would their warps combine and just form a big bowl which the both of them fall towards each other at the same rate? Also, is there a distance at which gravitation will have a negligible effect? Or is the warping of spacetime seemingly infinite, decreasing it's slope infintessimally?

Thank you for your answer, also please correct me if I have any misconceptions about how gravity and the warping of space works, and if space actually warps the same as if a mass was placed on a fabric?

You have a lot of questions. I will do my best to knock them out one by one.
2 identical objects move differently through each others spatial curvature depending on their initial velocity and position.
2 clones moving toward each other will collide and conglomerate into one body ( truly combining their warps)
2 clones orbiting around each other will orbit around their center of mass.
Now space is a lot more malleable than tectonic plates. Therefore no " mountain " between them can form. The curvatures just merge together. Picture an extremely tough rubber sheet and two equivalent bowling bowls rolling down to the center. Their respective curvatures are merged into the one of a body twice as big. Now the rubber sheet and bowling ball analogy is good but don't over extend it.
1. It doesn't include time
2. It doesn't include the third dimension
3. It is elastic deformation space can bend in a lot more ways without snapping.
Also yes space time asymptotically approaches Minkowski space time as one gets infinitely far away.
 

Related to Gravitation, 2 objects of same properties

1. How does the force of gravity between two objects depend on their masses?

The force of gravity between two objects is directly proportional to the product of their masses. This means that the larger the masses of the objects, the stronger the force of gravity between them will be.

2. What factors affect the gravitational force between two objects?

The gravitational force between two objects depends on their masses and the distance between them. The force decreases as the distance between the objects increases.

3. How does the gravitational force between two objects change if one of the objects is moved to a different location?

The gravitational force between two objects will decrease if one of the objects is moved away from the other. This is because the distance between the objects has increased, which weakens the force of gravity between them.

4. What is the formula for calculating the force of gravity between two objects?

The formula for calculating the force of gravity between two objects is F = G x (m1 x m2) / d^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and d is the distance between them.

5. How does the force of gravity between two objects change if their properties are altered?

The force of gravity between two objects does not depend on their properties such as size, shape, or composition. As long as the masses of the objects and the distance between them remain the same, the force of gravity between them will not change.
