To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth – all that constitutes a wild dream worthy of Jules Verne.

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.

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.

Bullets are fast – even a 9-millimeter handgun launches lead at Mach 1. And the bigger the bullet gets, the more grains of gunpowder it carries, the faster it goes. Modern rifles can fling the small pieces of metal at half the velocity needed to escape the gravitational pull of the Moon.

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.

Parents are the centre of a person‘s solar system, even as an adult. My dad had a stronger gravitational pull than most, so his absence was bound to leave a deep and lasting void.

The three-body problem is a term borrowed from physics. It is a phenomenon that can basically be explained like this: Two objects in space can interact in a predictable fashion rotating around each other due to their gravitational pull. But if a third object is introduced, it makes their interaction more complicated.

The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.

Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy.

The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.

When we get out to other planets in the solar system, we’ll use the gravitational pull of each planet to help launch us to the next.

Yet another proposal would have us rocket the waste into the sun, but, as you‘re probably aware, about one in ten of our space shots doesn’t quite make it out of the earth’s gravitational field.

Music pulled me like a gravitational force. I entered college as a physics major but left as a Bachelor of Music, a degree with the same practical application as, say, one in the History of Chinese Poetry.

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they’re seen by their gravitational effect.

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.

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.

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

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.

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.

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 cyclic universe theory predicts no gravitational waves from the early universe.

If the universe sprung into existence and then expanded exponentially, you get gravitational waves traveling through space-time. These would fill the universe, a pattern of echoes of the inflation itself.

The Planck satellite may detect the imprint of the gravitational waves predicted by inflation. This would be quantum gravity written across the sky.

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.

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.

I hope that vigorous space exploration continues and that humankind will have a space station that resides between Earth and the moon. Outside the gravitational field of Earth, we could launch robotic spacecraft to other destinations in our solar system.

Ethereum is enabling a new form of financing in ICOs that is like a massive gravitational pull – dragging every entrepreneur with a sense for opportunity into its blackhole-level gravity.

The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.

I see musicians like Bonnie Raitt and Emmylou Harris as more than just musical icons: they are planets, with a gravitational pull – from how they flip their hair just-so when they bow, right down to their hearty backstage banter. It takes decades to learn the innuendos of being gracious and genuine all at once.

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 bottom is so big it’s got its own gravitational field.

The New York Times‘ was enigmatic: ‘Some unimaginable gravitational force is pulling our entire galaxy in the opposite direction.’ End of article. If you stop and think about that, we are recreating ourselves.

Parents are the centre of a person‘s solar system, even as an adult. My dad had a stronger gravitational pull than most, so his absence was bound to leave a deep and lasting void.

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.

Black holes do not emit light, so you visualize them through gravitational lensing – how they bend light from other objects.

Jupiter is so big and its gravitational pull so strong that man would find it difficult to move about on the surface. The answer is to whittle it down to proper size with terrajets and nuclear power, using the debris to increase the size of Jupiter’s moons so they, too, can be colonized.

When gravitational waves reach the earth, the waves stretch and squeeze space. This is a tiny stretch and squeeze. Far too small to detect with ordinary human senses.

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.

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.

The classical example of a successful research programme is Newton‘s gravitational theory: possibly the most successful research programme ever.

The detection of gravitational waves is truly a triumph of modern large-scale experimental physics.

I would like to mention astrophysics; in this field, the strange properties of the pulsars and quasars, and perhaps also the gravitational waves, can be considered as a challenge.
