Measurable Equivalence Principle violation arising from calculated extreme parity pair crystal lattices is proposed.

Measuring the Curvature of the Universe by Measuring the Curvature of the Hubble Diagram Two groups are measuring distant supernovae with the goal of determining whether the Universe is open or closed by measuring the curvature in the Hubble diagram. The figure below shows both data sets: Perlmutter et al. (1997) and (1998) in black and Garnavich et al. (1997) in orange. The curves show a closed ...

General relativity in the global positioning system Neil Ashby University of Colorado n_ashby@mobek.colorado.edu The Global Position System (GPS) consists of 24 earth-orbiting satellites, each carrying accurate, stable atomic clocks. Four satellites are in each of six different orbital planes, of inclination 55 degrees with respect to earth's equator. Orbital periods are 12 hours (sidereal), so ...
