Mike Tobar—Honourable Mention at Gravity Research Foundation International Essay Competition

EQUS Chief Investigator Mike Tobar has won an honourable mention for an international essay competition, run by the Gravity Research Foundation, along with co-authors RY Chiao (School of Natural Sciences, University of California, Merced), NA Inan (ClovisCommunityCollege; School of Natural Sciences, University of California, Merced; Department of Physics, California State University Fresno) and DA Singleton (Department of Physics, California State University Fresno):

Temporal Pound–Rebka experiment as gravitational Aharonov–Bohm effect

One of the classical tests of general relativity is the precision measurements by Pound and Rebka of the redshift or blueshift of photons in a gravitational field.  This essay lays out a temporal version of the Pound–Rebka experiment.  The emission and absorption of photons occurs at different times, rather than at different spatial locations as in the original Pound–Rebka experiment.  This temporal Pound–Rebka experiment is equivalent to a gravitational Aharonov–Bohm effect and is testable using current or near-future satellite experiments.
