Variable Modified Newtonian Mechanics VIII: Ultra faint dwarfs in Milky Way
James Chi Chung Wong
Velocity dispersions of Ultra faint dwarf (UFD) galaxies are observed to deviate significantly from the Baryon Tully Fisher Relation of the massive galaxies (BTFR). We propose a so…
An extensive universe avoids phantom dark energy
James C. C. Wong, Ray J. Rivers
A major challenge in cosmology and astrophysics is the phantom dark energy used to explain the data of DESI DR2 BAO. Assuming that the degrees of freedom of the universe are (d=3)…
Variable Modified Newtonian Mechanics IV: Non Rotating Galaxies
James C. C. Wong
At it stands, the model does not anticipate the early emergence of massive galaxies. Canonical Modified Newtonian Dynamics (MOND) seems to fail at late time solar system sca…
Un-modelled Pioneer 10/11 clock acceleration from the Schwarzschild metric and Flyby energy Increase
James C. C. Wong
When a space-craft reaches a large radial velocity, we expand the time dependent radial distance to linear order in time. In the Schwarzschild metric this linear term in time leads…
Variable Modified Newtonian Mechanics III: Milky Way Rotational Curve
James C. C. Wong
For a point mass residing in an expanding universe, within General Relativity (GR), a new metric [1} is found to lead to a cosmological background dependent MOND-like acceleration…
A Baseline model for Modified Newtonian Mechanics I: The Early Universe
James C. C. Wong, Ray J. Rivers
In modelling galaxy structure formation, neither Cold Dark Matter (CDM) nor canonical Modified Newtonian Dynamics (MOND) (Milgrom [1]) can easily accommodate the appearance of mass…
