We're going to be seeing things from regions in the universe where Einstein is the whole story. Newton you can forget about.

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 concept of what we're looking for is so important. The fact that the effect is tiny is just our misfortune.
