## Lambda-VDM Model: a Testable Modification of Lambda-CDM

**Authors:** David Brown

Milgrom’s MOdified Newtonian Dynamics (MOND) implies that the Lambda-Cold-Dark-Matter (Lambda-CDM) model is significantly wrong. Based upon a speculative, MOND-based theory of quantum gravity, this brief communication describes a Lambda-Virtual-Dark-Matter (Lambda-VDM) model that allows for precise testing of the speculative theory of quantum gravity. There are 2 basic new ideas: Idea 1 is to replace the -1/2 in the standard form of Einstein’s field equations by -1/2 + dark-matter-compensation-constant, where this constant is approximately sqrt((60±10)/4)) * 10^‐5. Idea 2 is that dark matter has positive gravitational mass-energy and zero inertial mass-energy and that the universe converts ordinary matter into dark matter over cosmological time; the % of ordinary matter monotonically decreases over time according to a precise formula; when the % of ordinary matter is sufficiently close to zero the entire universe undergoes an instantaneous quantum collapse. Part of Idea 2 is that dark matter is always virtual mass-energy and can never be directly measured. The Lambda-VDM model might provide a resolution of the Photon Underproduction Crisis.
