The cyclic universe theory predicts no gravitational waves from the early universe.
Black holes destroy any objects that happen to fall victim to their gravitational pull.
Every time you accelerate - say by jumping up and down - you're generating gravitational waves.
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.
I grossly underestimated the gravitational pull of America's justice system toward white supremacy.
Black holes do not emit light, so you visualize them through gravitational lensing - how they bend light from other objects.
We cannot explain the phenomenon of gravitational lensing without general relativity, and this is where MOND spectacularly fails.
General relativity predicts that time ends inside black holes because the gravitational collapse squeezes matter to infinite density.
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.
The classical example of a successful research programme is Newton's gravitational theory: possibly the most successful research programme ever.
The Planck satellite may detect the imprint of the gravitational waves predicted by inflation. This would be quantum gravity written across the sky.
Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.
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?
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.
Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.
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.
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.
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.
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.
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.
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.
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.
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.
The human body experiences a powerful gravitational pull in the direction of hope. That is why the patient's hopes are the physician's secret weapon. They are the hidden ingredients in any prescription.
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.
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.
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.
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.
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.
Gravitational waves will bring us exquisitely accurate maps of black holes - maps of their space-time. Those maps will make it crystal clear whether or not what we're dealing with are black holes as described by general relativity.
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.
I think about the cosmic snowball theory. A few million years from now the sun will burn out and lose its gravitational pull. The earth will turn into a giant snowball and be hurled through space. When that happens it won't matter if I get this guy out.
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.
Why do guests always end up in the kitchen at parties? Is it a social phenomenon? Some strange gravitational pull? I don't know, but one thing is for sure: If your friends are going to congregate in your kitchen, you'd better make it as nice as possible.
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 have this friend who has a theory that lots of towns have energies. And, for instance, certain places in Alabama have bad ones because they were built on reservations or built on cemeteries or something. But Nashville has a really gravitational, magnetic pull.
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 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.
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.
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.
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.
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.
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.
