The field equation of Einstein's General Theory of
"Relativity has never before been solved to calculate the gravitational field of a mass moving close to the speed of light. Felber's research shows that any mass moving faster than 57.7 percent of the speed of light will gravitationally repel other masses lying within a narrow 'antigravity beam' in front of it. The closer a mass gets to the speed of light, the stronger its 'antigravity beam' becomes."Dr Felber is looking for volunteers to test this theory. I will pray that no huge masses get in your way when v < .577c.
