Curvature, Galactic Dynamics and Cosmic Repulsion
Philip D. Mannheim
We show that a cosmological negative spatial curvature can account for both a recently identified phenomenological imprint of the global Hubble flow on galactic rotation curves and…
The equivalence principle in classical mechanics and quantum mechanics
Philip D. Mannheim
We discuss our understanding of the equivalence principle in both classical mechanics and quantum mechanics. We show that not only does the equivalence principle hold for the traje…
How We Got Into The Dark Matter Fix And How We Can Get Out
Philip D. Mannheim
The recent discovery of cosmic repulsion represents a major challenge to standard gravity, adding an apparent missing energy problem to its still not yet adequately resolved missin…
Curvature and Cosmic Repulsion
Philip D. Mannheim
Some recent supernovae studies have extended the distance versus velocity Hubble plot to very high redshift, and have revealed the apparent presence of a cosmic repulsion. We show…
