Very clear explanation. Now fit your denser than average and less dense than average locations in space into a theory of universal expansion (approximately three times the speed of light) and how the inertia of masses resists this expansion resulting in gravitational tension (Newton’s Gravitational Equation (for normal space) as an analog of interfacial tension). Myself (S.B.K. Burns) and S.G. Advani (University of Delaware) ran a Saffman-Taylor Instability model of a two-dimensional (low energy) expanding boundary that gives insight into this problem: https://link.springer.com/article/10.1007/BF00191691
