Exact Relativistic 'Antigravity' Propulsion

TL;DR

This paper demonstrates that relativistic effects can cause gravitational repulsion at high speeds and proposes a method for rapid payload acceleration using moving masses in a relativistic framework.

Contribution

It provides an exact relativistic analysis of gravitational interactions involving moving masses, revealing conditions for gravitational repulsion and propulsion at near-light speeds.

Findings

Gravitational repulsion occurs at speeds above 1/√3 times the speed of light.

A moving mass can accelerate a payload to near-light speeds with minimal stress.

Relativistic gravitational effects enable potential propulsion mechanisms.

Abstract

The Schwarzschild solution is used to find the exact relativistic motion of a payload in the gravitational field of a mass moving with constant velocity. At radial approach or recession speeds faster than 3^-1/2 times the speed of light, even a small mass gravitationally repels a payload. At relativistic speeds, a suitable mass can quickly propel a heavy payload from rest nearly to the speed of light with negligible stresses on the payload.
