I had goose bumps reading the interview with the father of LIGO, Rainer Weiss, who imagined LIGO in a 1972 paper, 44 years ago!
“I feel an enormous sense of relief and some joy, but mostly relief. There’s a monkey that’s been sitting on my shoulder for 40 years, and he’s been nattering in my ear and saying, “Ehhh, how do you know this is really going to work? You’ve gotten a whole bunch of people involved. Suppose it never works right?” And suddenly, he’s jumped off. It’s a huge relief.”
