A Quote by 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.
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.
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.
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.
Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.
Even if 'going retrograde' or 'moving into Aquarius' were real phenomena, something that planets actually do, what influence could they possibly have on human events? A planet is so far away that its gravitational pull on a new-born baby would be swamped by the gravitational pull of the doctor's paunch.
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.
I spend quite a bit of time thinking about my students. I look at them, at their work, I listen to what they tell me, and try to figure out who they might become in the best of all possible worlds. This is not easy. Students try to give you clues; sometimes they look at you as if imploring you to understand something about them that they don't yet have the means to articulate. How can one succeed at this? And how can one do it 20 times over for all the students in a class? It's impossible, of course. I know this, but I try anyway. It's tiring.
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.
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.
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.
Practitioners of SI do not feel ourselves to be therapists. The gravitational field is the therapist. What we do is prepare the body to receive the support from the gravitational field which gives a greater sense of well being.
For in this world, marked by sin, the gravitational pull of our lives is weighted by the chains of the "I" and the "self." These chains must be broken to free us for a new love that places us in another gravitational field where we can enter new life.
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.
Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.
The detection of gravitational waves is truly a triumph of modern large-scale experimental physics.
Every time you accelerate - say by jumping up and down - you're generating gravitational waves.
