Gravitational Physics Quotes

I arrived at Princeton as a graduate student from the University of Manitoba in 1958. To my great good fortune, I fell into work with Bob Dicke, a truly great physicist who decided a few years before that that gravity is too important to ignore, as it had been in recent years in physics.

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.

Evidence in support of general relativity came quickly. Astronomers had long known that Mercury’s orbital motion around the sun deviated slightly from what Newton’s mathematics predicted. In 1915, Einstein used his new equations to recalculate Mercury’s trajectory and was able to explain the discrepancy, a realization he later described to his colleague Adrian Fokker as so thrilling that for some hours it gave him heart palpitations.

My passion is to understand the non-linear dynamics of warped space-time, and the ideal venue for this is black-hole collisions.

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

The waves are subtle, altering spacetime and the distance between objects as far apart as the Earth and the Moon by much less than the width of an atom. As such, gravitational radiation has not been directly detected yet. We hope to change that soon.

The triumph is that the waveform we measure is very well represented by solutions of these equations. Einstein is right in a regime where his theory has never been tested before.

All the standard equations of mathematical physics can be separated and solved in Kerr geometry.

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.
