Einstein's general theory of relativity predicted that huge bodies accelerating in space should give off gravity in waves. These gravity waves would travel at the speed of light. Physicists believed Einstein, but until University of Maryland physicist Joseph Weber published the results of a ten-year experiment in 1968, these waves had not been proven to exist.

Detecting Gravity

Weber posited that gravity waves should not be expected to be strong, so he would need a sensitive detector. But then he would need a way to eliminate the interference Earth tremors, passing cosmic rays, electromagnetic radiation, and even atomic ...
