# Gravity at atomic levels, first time post

Peter Pan
I have very little training in the area of Physics, but enough to understand most of what is said on this forum. This is a first time post.

My question has to do with gravity on an atomic level. This question is for those of you familiar with trying to combine all four natural forces.

First these are a few things I understand to be true:
1 Gravity is the weakest of the 4 natural forces.
2 The current problem with the unified field theory is combining all 4 forces into one equation.
3 We can currently combine strong nuclear force, weak nuclear force, and electromagnetism into one equation.
4 Gravity is actually the result of a body of mass bending space-time.

My question is this…
Is space-time elastic and if so does it have a critical mass needed to bend it?

For instance if a bowling ball or a cannon ball is set on a trampoline, the trampoline will bend. But, if a grain of sand is set on a trampoline it will not bend the material. Could this example parallel real space-time? A star has enough mass to curve space-time, while and atom or a particle does not. I believe that if this is the case, that a lot of the problems due to using gravity on an atomic level would be solved.

This may not be a new idea. I have not the foggiest. Please lead me to any research already done on the subject or give me your own expertise on the subjuct.

Thank you,
Pan

Hello Pan.
My comment'll be very short.

Correctly. This is well known so called geometrical interpretation.

Gravity may differ on small scales due to branes' or strings' extradimensionality at those levels - .1 mm, for instance. Experiments are currently being carried out to determine any accelerative deviation from accustomed geometrodynamics there.
