New Theories / Re: What exactly is gravity?
« on: 11/12/2019 14:59:27 »If gravity is a force, that what sort of energy is released when gravitational potential decreases?
It depends on the specifics. In some cases, that energy is released in the form of gravitational waves (like in merging black holes). In other cases, it would just be a transformation of gravitational potential energy into kinetic energy (such as when you drop a stone).
The EM force, the weak and strong nuclear forces all give off photons when potential lowers.
The photon is uniquely associated with the electromagnetic force. If an excited atomic nucleus releases a photon when it goes back into a relaxed state, that is because the constituent nucleons contain electric charges. The strong force is always associated with electric charge because all quarks are charged.
so what is the type of photon given off by lowering gravitational potential energy?
Photons don't come in different types (except for certain properties such as wavelength, but that's true of all particles anyway).
If there are no photons, it is really a force?
Yes. The presence or absence of photons has nothing to do with whether there is a force present or not.
