Gravity at atomic levels, first time post

Click For Summary
SUMMARY

This discussion centers on the concept of gravity at atomic levels and its relationship with space-time. Key points include the acknowledgment that gravity is the weakest of the four natural forces and the ongoing challenge of unifying all forces into a single equation. The idea that gravity may have a critical mass threshold for bending space-time is explored, drawing parallels to how objects like bowling balls and cannon balls affect a trampoline. The discussion references the concept of quantized gravity, which is a significant aspect of theories of everything (TOEs) proposed by physicists such as Stephen Hawking and Brian Greene.

PREREQUISITES
  • Understanding of the four fundamental forces of nature
  • Familiarity with general relativity and the concept of space-time

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.
 
Welcome Pete!

If I have read you correctly, you're suggesting that the curvature of spacetime we call "gravity" may have a lower critical limit; a threshold below which it cannot happen. So spacetime would have to be curved by at least this much, or none at all, right?

If that is what you're saying, then you are correct in your suspicion that you're not the first to think that. What you've arrived at is the idea that gravity may be "quantized", which is a key component to most potential TOE's. So even though you didn't get there first, you are in very good company (and there is tremendous value in the fact that you got there on your own).

If you do a search on "quantized gravity", you can probably find a lot of info written by great minds like Hawking and Green, who have come to the same conclussion.
