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.

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.

Rainer Weiss

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.

Rainer Weiss

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

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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.

Rainer Weiss

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

Rainer Weiss

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

Rainer Weiss

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

Rainer Weiss

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.
