👉 The term "homopause" refers to a point in time when there is no more energy or matter available for further expansion. It occurs during the perihelion of a planet's orbit around its star, where all of the energy and matter are conserved. During this period, the planet experiences a state of stability known as a "paradoxical equilibrium," where it appears to be at the point where its gravitational pull would cause it to collapse into a black hole due to tidal forces.
