Let me write a review of some non-newtonian potentials and forces. There are some interesting potentials beyond the purely newtonian-like/coulombian-like potential energy and force. In 3 dimensions of space (3+1 spacetime), the gravitational potential energy and the universal law of … Continue reading
Some conclusions of this fascinating subject and thread about the mythical spacetime foam: (1) CDM(Cold Dark Matter) and MOND seems to be complementary descriptions of the same dynamics and phenomenology. (2) MOND force law works at galactic scales. This can … Continue reading
The second post in this thread is completely speculative. 1) Suppose that Dark Energy is some kind of “fluid” made of some long wavelength “particles” or “exotic stuff”. 2) How different are those “Dark Energy particles” from the particles we … Continue reading
