Quotes from Rainer Weiss

We've seen black holes, which is already wonderful. We also expect to see the merger of neutron stars, and that was a thing that actually gave this field a certain credibility when it was discovered that there were pairs of neutron stars in our galaxy, and people stopped laughing at us when that was found out.

The whole idea of gravity curling up space, that is the epitome of what is going on in a black hole. I would've loved to have seen Einstein's face if he were presented with the data that we actually discovered such a thing, because he himself probably didn't believe in much of it.

This is the first real evidence that we've seen now of high gravitational field strengths: monstrous things like stars moving at the velocity of light, smashing into each other, and making the geometry of space-time turn into some sort of washing machine.

My father was a dictator in the true German sense. He suppressed my mother.

The rule has been that when one opens a new channel to the universe, there is usually a surprise in it. Why should the gravitational channel be deprived of this?

We expect surprises. There has to be surprises.

If the wave is getting bigger, it causes the time to grow a little bit. If the wave is trying to contract, it reduces it a little bit. So, you can see this oscillation in time on the clock.

For reasons probably related to the popular vision of Albert Einstein and, also, the threat posed by black holes in comic books and science fiction, our gravitational wave discoveries have had an amazing public impact.

I thought that there must be an easier way to explain how a gravitational wave interacts with matter: If one just looked at the most primitive thing of all, 3D floating masses out in space, and look at how the space between them changed because of the gravitational wave coming between them.

The obvious thing to me was, let's take freely floating masses in space and measure the time it takes light to travel between them. The presence of a gravitational wave would change that time. Using the time difference, one could measure the amplitude of the wave.

A gravitational wave is a very slight stretching in one dimension. If there's a gravitational wave traveling towards you, you get a stretch in the dimension that's perpendicular to the direction it's moving. And then perpendicular to that first stretch, you have a compression along the other dimension.

Many of us on the project were thinking if we ever saw a gravitational wave, it'd be an itsy bitsy little tiny thing; we'd never see it. This thing was so big that you didn't have to do much to see it.

I said, suppose you take a light - I was thinking of just light bulbs because, in those days, lasers were not yet really there - and sent a light pulse between two masses. Then you do the same when there's a gravitational wave. Lo and behold, you see that the time it takes light to go from one mass to the other changes because of the wave.

Every time you accelerate - say by jumping up and down - you're generating gravitational waves.

It's very, very exciting that it worked out in the end that we are actually detecting things and actually adding to the knowledge, through gravitational waves, of what goes on in the universe.

You know the Einstein waves can be thought of as a distortion of space and time. But the way we see it, we see it as a distortion of space. And space is enormously stiff. You can't squish it; you can't change its dimensions so easily.

Gravitational waves, because they are so imperturbable - they go through everything - they will tell you the most information you can get about the earliest instants that go on in the universe.

Space is much stiffer than you imagine; it's stiffer than a gigantic piece of iron. That's why it's taken so damned long to detect gravitational waves: to deform space takes an enormous amount of energy, and there are only so many things that have enough.

The waves travel with the velocity of light and slightly squeeze and stretch space transverse to the direction of their motion. The first waves we measured came from the collision of two black holes each about 30 times the mass of our sun.

We know about black holes and neutron stars, but we hope there are other phenomena we can see because of the gravitational waves they emit.

Einstein had looked at the numbers and dimensions that went into his equations for gravitational waves and said, essentially, 'This is so tiny that it will never have any influence on anything, and nobody can measure it.' And when you think about the times and the technology in 1916, he was probably right.

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.

What was done is measure directly, with exquisitely sensitive instruments, gravitational waves predicted about 100 years ago by Albert Einstein. These waves are a new way to study the universe and are expected to have significant impact on astronomy and astrophysics in the years ahead.

The waves from all the different parts of a sphere would cancel each other out. You need motion that's nonspherical.
