Reversed Gravitational Acceleration for High-speed Particles
Hans C. Ohanian
TL;DR
This paper investigates the behavior of high-speed particles in Schwarzschild spacetime, revealing a reversal in gravitational acceleration at relativistic speeds while confirming the persistent attractive nature of gravity.
Contribution
It demonstrates that particles exceeding a certain speed experience a reversal in gravitational acceleration in Schwarzschild coordinates, a novel insight into relativistic gravity effects.
Findings
High-speed particles decelerate when falling inward
Particles accelerate upward at high speeds
Reversal occurs at approximately 1/√3 times the speed of light
Abstract
Examination of the free-fall motion of particles of extremely high-speed in the Schwarzschild geometry reveals that the gravitational acceleration of such particles is reversed when measured in Schwarzschild coordinates. High-speed particles decelerate when moving radially downward, and they accelerate when moving upward. The onset of this abnormal behavior occurs at a speed of 1/Sqrt(3) times the local value of the speed of light. However, the gravitational force always remains attractive.
