Quotes About Gravitational

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.

But to some people home was home, a complex of feeling far beyond rationality, a sort of grid or gravitational field in which the personality itself took its geometrical shape. While for others, a place was just a place, and the self free of all that, the same no matter where it was. One kind lived in the Einsteinian curved space of home, the other in the Newtonian absolute space of the free self.

If the imprint is really due to gravitational waves from the big bang, then this is the type of cosmological discovery that comes along perhaps once every fifty years.

I cofounded the LIGO Project in 1983 (together with Rainer Weiss at MIT and Ronald Drever at Caltech). I formulated LIGO's scientific vision, and I spent two decades working hard to help make it a reality. And LIGO today is nearing maturity, with the first detection of gravitational waves expected in this decade.

An important memory is like a gravitational field--the mind is compelled to return to it again and again. It is like a moon; it lives in light and shadow.

if the Sun disappeared instantaneously, the Earth would continue to orbit the position of the Sun for seven minutes until the bad news reached us in the form of gravitational waves.

We said that with initial LIGO, detections would be possible, and with Advanced LIGO, detections would be probable.

The emotional intensity of a significant relationship is a stimulus that intensifies the drive toward togetherness. As each partner finds personal meaning in the relationship, the togetherness force becomes more intense, as though some sort of gravitational force were operating.

In general, when we consider an object in a superposition of two spatially displaced states, we simply ask for the energy that it would take to effect this displacement, considering only the gravitational interaction between the two. The reciprocal of this energy measures a kind of 'half-life' for the superposed state. The larger this energy, the shorter would be the time that the superposed state could persist.

In a flat universe, and only in a flat universe, the total average Newtonian gravitational energy of each object moving with the expansion is precisely zero! This is what makes a flat universe so special. In such a universe the positive energy of motion is exactly canceled by the negative energy of gravitational attraction.

The church needs to be so clear about its identity as the body of Christ that everything it does generates a gravitational pull toward the heart.

There can be no space nor any part of space without gravitational potentials; for these confer upon space its metrical qualities, without which it cannot be imagined at all. The existence of the gravitational field is inseparably bound up with the existence of space.

In gravitational fields there are no such things as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in general relativity.

This has led to an oft-quoted analogy that an atom's structure is similar to the solar system, the essential differences being the overall scale and that there is electromagnetic instead of gravitational attraction. However, this is a poor analogy for several reasons, one being that in reality the atom is far emptier than the solar system.

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.

It is the cosmological vacuum energy that contributes a repulsive lambda force to the gravitational force of Newton.

The pulsar is like a lighthouse beam spinning at high speed. Every time it comes around to face us we see a flash. Its rotation can be very accurately monitored by timing observations of its periodic pulses. Twenty years of observations have shown that the pulsing of the binary pulsar is slowing at exactly the rate predicted if the system is losing energy by radiating gravitational waves at the rate predicted by Einstein's theory.

The sun, with all the planets revolving around it, and depending on it, can still ripen a bunch of grapes as though it had nothing else in the universe to do.

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

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

Normally, the energy of the particle is still positive, but the gravitational field inside a black hole is so strong that even a real particle can have negative energy there. It is therefore possible, if a black hole is present, for the virtual particle with negative energy to fall into the black hole and become a real particle or antiparticle.

Real gravitons make up what classical physicists would call gravitational waves, which are very weak—and so difficult to detect that they have not yet been observed. The

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.

It wasn't a matter of conscious choice, necessarily, just a matter of gravitational pull, the way integration always worked, a one-way street. The minority assimilated into the dominant culture, not the other way around. Only white culture could be neutral and objective. Only white culture could be nonracial, willing to adopt the occasional exotic into its ranks.
