Preliminary Sensitivity Study for a Gravitational Redshift Measurement with China's Lunar Exploration Project
Cheng-Gang Qin, Tong Liu, Xiao-Yi Dai +5
General relativity (GR) is a highly successful theory that describes gravity as a geometric phenomenon. The gravitational redshift, a classic test of GR, can potentially be violate…

The CR Volume for Black Holes and the Corresponding Entropy Variation: A Review
Shad Ali, Tong Liu
This paper reviews the work done on black hole interior volume, entropy, and evaporation. An insight into the basics for understanding the interior volume is presented. A general a…
