| contents | <p>This paper explores a possible microscopic mechanism for gravitational phenomena. We propose that space is filled with a discrete ground-state particle sea at the lowest energy state. Observable matter corresponds to local excitations of this sea, manifesting as the displacement of ground-state particles and a consequent density increase in surrounding regions. The sea’s density may evolve with cosmic expansion, but the present work focuses on its static gradient effect. Light propagation corresponds to in-situ perturbations of the ground-state particle sea—particulate in essence, wave-like in appearance. Within this physical picture, the density distribution of the ground-state particle sea satisfies the Poisson equation<br>∇^2 ρ=λn<br>while the gravitational potential is proportional to the density gradient,<br>∇Φ=γ∇ρ<br>Under the static weak-field approximation, this model is equivalent to Newton’s law of universal gravitation. We further discuss the correspondence between this model and general relativity regarding the propagation of gravitational waves, and propose possible experimental tests using techniques such as ultracold atom interferometry.</p> |
