摘要

In 1969, Rainer Weiss was a young MIT professor. At the time gravitational waves were a theoretical curiosity: Einstein himself took years to be convinced by his own prediction that moving cosmic bodies would send out ripples through space-time. Then physicist Joseph Weber claimed to have recorded one on a xylophone-like instrument he called a resonant bar detector. Weiss takes up the story. The students on my course were fascinated by the idea that gravitational waves might exist. I didn't know much about them at all, and for the life of me I could not understand how a bar interacts with a gravitational wave. I kept thinking, well, there's one way I can explain how gravitational waves interact with matter. I said, suppose you take a light -I was thinking of just light bulbs because, in those days, lasers were not yet really there - and sent a light pulse between two masses. Then you do the same when there's a gravitational wave.
