Rainer Weiss : (2) " It’s a spectacular signal. It’s a signal many of us have wanted to observe since the time LIGO was proposed. It shows the dynamics of objects in the strongest gravitational fields imaginable, a domain where Newton’s gravity doesn’t work at all, and one needs the fully non-linear Einstein field equations to explain the phenomena. " - Rainer Weiss " When we initially proposed LIGO, the only sources that we were really contemplating were supernovae. We thought we would see something like one a year, maybe even ten a year.
