about gravity!?

Question

I know that Newton's formula is : F= (G*M*m)/ d2
mathematicly if the distance is 0 the force will be infinite is that true in small things>> if we succed in confusing two gravity points of two objects will it be an infinit force.... sure not ... but why

Answer 1

There are other forces at play at very close range, like the electrostatic repulsion between two proton for instance so achieving the two things close enough bit is hard to achieve; but technically yes, if you could put two small enough and massive enough object in a single location, the gravity between them would be infinite. And guess what? This is what is happening in a black hole, where the mass is condensed to such a degree that space if affected. The mass is assumed to be concentrated in a singularity, which could be infinitely stretched space that we cannot observe (because it is infinitely far, and is beyond the event's horizon).

Answer 2

The Strong Nuclear Force (also referred to as the strong force) is one of the four basic forces in nature (the others being gravity, the electromagnetic force, and the weak nuclear force). As its name implies, it is the strongest of the four. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Its main job is to hold together the subatomic particles of the nucleus (protons, which carry a positive charge, and neutrons, which carry no charge. T

Answer 3

If the distance is zero then the equation is moot. The purpose of the equation is to quantify the force acting BETWEEN 2 bodies. If the distance between them is zero then they are the same thing, one thing, not 2.

Because Muskrat Susie and Muskrat Sam are doing the jitterbug in Muskrat Land!
