The whole world tried to reproduce the Weber experiments.

I wasn't unpopular. I didn't have any trouble getting girls.

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

We haven't found anything that we can't explain at all. I hope that will happen.

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

The field equations and the whole history of general relativity have been complicated.

Receiving money for something that was a pleasure to begin with is a little outrageous.

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

Over and over in the history of astronomy, a new instrument finds things we never expected to see.

There was a person who thought I was OK. I wasn't a complete dope. I got some confidence out of that.

I prefer really often to talk to high school students, mostly because I think they're the future for us.

People say, 'I failed out of college! My life is over!' Well, it's not over. It depends on what you do with it.

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

By the time we made the discovery in 2015, the National Science Foundation had put close to $1.1 billion into it.

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

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

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

We knew about black holes in other ways, and we knew about neutron stars - well, those are the two things that ultimately got seen.

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.

Experimentally, we now have demonstrated that Einstein's theory is right in strong gravitational fields. That's important to a lot of people.

We live in an epoch where rational reasoning associated with evidence isn't universally accepted and is, in fact, in jeopardy. That worries me a lot.

We are all enormously indebted to the National Science Foundation of the United States and the American public for steady support over close to 50 years.

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?

You think Earth's gravity is really something when you're climbing the stairs. But, as far as physics goes, it is a pipsqueak, infinitesimal, tiny little effect.

We'll have all sorts of crazy signals. And you'd be a damned fool if you didn't look for things you weren't expecting, because that's probably what you're going to see first.

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.

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.

Observing gravitational waves would yield an enormous amount of information about the phenomena of strong-field gravity. If we could detect black holes collide, that would be amazing.

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.

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.

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.

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.

My parents were singularly uninterested in me. My father was too self-centered and too busy with his own practice to pay a lot of attention to me, and my mother was probably deflected more by my sister.

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.

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.

One of the things I sort of dreamt about awhile ago is that if Einstein were still alive, it would be absolutely wonderful to go to him and tell him about the discovery, and he would have been very pleased, I'm sure of that.

The fact that this radiation is so penetrating - nothing stops it - makes it so you can look for things that you have never seen before, and you can look at things you know in a way that's new. That is really the big step forward.

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.

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.

Why do you do science? In this particular case, we don't have a very good reason to be doing this except for the knowledge that it brings. This research is especially important to young people. We all want to know what's going on in the universe.

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.

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.

I didn't understand the Weber bar and how gravitational waves interacted with it. I sat and thought about it over a weekend, trying to prepare for the lecture for the following Monday. I asked myself how would I do it. The simplest way... was a thought experiment.

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.

We were looking almost one-tenth of the way to the edge of the universe. We're planning to use the facilities we have to make improvements by another factor of 10... a strain sensitivity that is 10 times smaller. This means looking 10 times further out into the universe.

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.

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.

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.

All at once, funding was gone due to the Mansfield Amendment, which was a reaction to the Vietnam War. In the minds of the local RLE administrators, research in gravitation and cosmology was not in the military's interest, and support was given to solid-state physics, which was deemed more relevant.

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.
