Quotes About LIGO

When the signal reached LIGO from a collision of two stellar black holes that occurred 1.3 billion years ago, the 1,000-scientist-strong LIGO Scientific Collaboration was able to both identify the candidate event within minutes and perform the detailed analysis that convincingly demonstrated that gravitational waves exist.

I cofounded the LIGO Project in 1983 (together with Rainer Weiss at MIT and Ronald Drever at Caltech). I formulated LIGO's scientific vision, and I spent two decades working hard to help make it a reality. And LIGO today is nearing maturity, with the first detection of gravitational waves expected in this decade.

We said that with initial LIGO, detections would be possible, and with Advanced LIGO, detections would be probable.

The first thing I think, I was building computers, I started to build a computer when I was 17 or 18 at home, an IBM compatible computer, and then I started to sell computers, and when I sold a computer to a company called Ligo I think, and they were selling systems which became blockbuster.

All of this technology wasn't available to Einstein. I bet he would've invented LIGO.

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.

Over years, the noise level will be brought down, and LIGO will be three times better and see three times farther.

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.

The technical challenges were technical challenges that were not unbeatable; it was just that we had to learn how to do things and how to build a sensitive enough device. That took us 20 years after we built the first version of the LIGO detector.
