I know it would be a small force, but what is the equation to calculate the gravity between the three quarks in the proton (uud), and then the antiproton ?
Is this not then a good example of what Einstein was talking about--that QM theory is limited, since it cannot explain the most simple many-body (e.g., 3 quarks within a nucleon) gravity interaction ?jtbell said:I don't think it's possible to answer this question (yet), since we don't have a generally-accepted quantum theory of gravity, nor the experimental means to test such a prediction.

Yes, thank you for your response. How exciting if we do find that gravity has new properties at distances less than 10^-15 meters. Yet, should we not at least in theory (via QM) be able to derive the equations that I look for in the OP--I care not if the answer says the force is not significant, I look for the mathematics that appears to not exist (anywhere !). I find it fascinating that such a simple question as presented in OP stumps exact mathematical answer via theory of QM (and, as explained by Selfadjoint, GR as well). It almost seems like we travel along the incorrect paradigm as to topic of gravity at quantum scale--perhaps not out-of-box thinking needed, but a new box.Physics Monkey said:... Still, we shouldn't shortchange the theory too much. With our assumptions in place, naive as they may be, we can talk about the gravitational energy of quarks and we can predict that it is completely irrelevant.
Quark gravity is a theoretical concept that suggests that the force of gravity between two particles is caused by the exchange of virtual quarks. In protons and antiprotons, the strong nuclear force between the quarks is much stronger than the gravitational force, so the effects of quark gravity are negligible.
The equations and formulas used to calculate quark gravity in protons and antiprotons are complex and involve quantum field theory. They take into account the masses and spin of the quarks, as well as the distance between them and the strength of the strong nuclear force. These calculations are still an active area of research.
No, protons and antiprotons are also affected by the strong nuclear force, electromagnetic force, and weak nuclear force. Quark gravity is a very weak force in comparison and is usually not considered in calculations of the behavior of particles.
Currently, there is no experimental evidence for quark gravity. The effects of quark gravity are predicted to be extremely small and difficult to detect, even with the most advanced technology. However, research is ongoing and future experiments may provide more insight into the role of quark gravity.
Quark gravity is a proposed extension of general relativity that attempts to explain the force of gravity at a smaller scale. However, it is still a theoretical concept and has not been fully integrated into the framework of general relativity. More research is needed to fully understand the relationship between quark gravity and other theories of gravity.
