Thank you VERY much, Cleonis. I truly appreciate the time you and others have spent helping me to understand this better. It is very generous of you and the other posters.

Thanks again Cleonis. If there is no scale distinction then are we left with a situation where the gravitational force is understood to result, fundamentally, from mass-induced space-time distortion, whereas other forces like the electromagnetic force result from a completely different...

Great information from all parties; thanks! So if I understand correctly, GR explains gravitational force as arising from a distortion of space-time by mass. The standard model will have an explanation for why mass exists if the Higgs Boson is discovered. But even now, physicists are...

I understand in general the types of situations where GR, Newtonian Gravity, and the Standard Model are usually used. What puzzles me is this: since the LHC is being used to look for the Higgs Boson, that suggests that the SM can explain gravity if the Higgs Boson is found. If that is...

Hmmm... What I am trying to understand is at what scale the transition from GR to the SM is generally accepted to be required to get results that conform to experiment. Is GR accepted as describing gravity down to the electron/proton/neutron level? If so, does that mean the SM picks up only...

Understood; thanks. I guess the next step for me is to understand whether the accepted thinking in physics is as follows: - a neutron, proton, electron, or atom will distort space-time as predicted by GR, and it is that distortion that produces the apparent gravitational forces responsible...

Again, exactly the type of result I was wondering about. Thank you. So would it be safe to say that, experimentally, it has been confirmed that neutrons and atoms experience gravity as predicted by Newtonian Physics? If so, how about protons and electrons? I would expect the experiments to...

Thanks again; I will check the reference. Regarding your comment above I am trying to understand it but am having trouble with the wording. Can you please help me understand what you mean there? Again, thank you!

Thanks; that's exactly the type of experiment I was wondering about. Are the results of the cold neutron falling experiments consistent with both the standard model and with GR? One would assume any conflict with either theory would have been pretty big news.

Right; that's what makes direct measurement difficult. I am wondering if anyone has ever devised a clever way to measure gravitational forces for particle.

Greetings, I've been pondering something and hope someone here can help me understand this. Simply put, have any experiments confirmed that individual atoms and/or free particles like neutrons, protons, electrons, anti-particles, etc are affected by gravity when they are not constituents of...
