Split cosmic artwork comparing MOND’s flat rotation curves with Lava-Void Cosmology’s viscous void-driven galaxy dynamics.

Lava-Void Cosmology and Modified Newtonian Dynamics (MOND)

By C. Rich Modified Newtonian Dynamics (MOND), proposed by Mordehai Milgrom in 1983, represents a phenomenological modification to Newtonian gravity in the ultra-low-acceleration regime […]

Lava-Void Cosmology and the Particle Dark Matter Hypothesis

By C. Rich The particle dark matter hypothesis has dominated cosmological modeling since the 1980s, motivated primarily by discrepancies between observed galactic rotation curves […]
