Gravitational Field Quotes & Sayings

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. — Rikki Ducornet

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. — Pope Benedict XVI

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. — Ida Rolf

Floating in the tank after a busy day's work brings a great relief. Suddenly all of the stimulation of holding one upright against gravity disappears. One realizes that a good deal of the fatigue accumulated during the day is caused by keeping one's body upright in a gravitational field. From a neurophysiological standpoint, one has immediately freed up very large masses of neurons from the necessity of constant computations (as to the direction of gravity, the programming by visual and acoustic inputs, by temperature changes, etcetera). For example, one's cerebellum is now freed for uses other than balancing the body. In summary, then, — John C. Lilly

Physicists traced the failure to the jitters of quantum uncertainty. Mathematical techniques had been developed for analyzing the jitters of the strong, weak, and electromagnetic fields, but when the same methods were applied to the gravitational field-a field that governs the curvature of spacetime itself-they proved ineffective. This left the mathematics saturated with inconsistencies such as infinite probabilities. — Brian Greene

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. — Albert Einstein

The current of time slowing down in the gravitational field of oblivion. — W.G. Sebald

Have you ever seen that video, where one of the Apollo astronauts, standing on the moon, drops a hammer and a feather side by side?" Giovanni shook his head. "The hammer and feather fall at exactly the same speed, they hit the ground at the same time. Same experiment that Galileo did from the leaning tower, dropping a pebble and a cannon ball. They both hit the ground at almost the same time. It doesn't matter what the mass of an object is - a grain of sand or an elephant - if they experience the same gravitational field, they'll accelerate exactly the same. — Matthew Mather

Of the many strange things Einstein's work revealed, the fluidity of time is the hardest to grasp. Whereas everyday experience convinces us that there is an objective concept of time's passage, relativity shows this to be an artifact of life at slow speeds and weak gravity. Move near light speed, or immerse yourself in a powerful gravitational field, and the familiar, universal conception of time will evaporate. If you're rushing past me, things I insist happened at the same moment will appear to you to have occurred at different moments. If you're hanging out near the edge of a black hole, an hour's passage on your watch will be monumentally longer on mine. — Brian Greene

Desire demands only a constant attention to the unknown gravitational field which surrounds us and from which we can recharge ourselves every moment, as if breathing from the atmosphere of possibility itself. A life's work is not a series of stepping-stones onto which we calmly place our feet, but more like an ocean crossing where there is no path, only a heading, a direction, which, of itself, is in conversation with the elements. — David Whyte

A singularity is a point or region in spacetime at which some physical quantity such as the density of mass or energy, the temperature, or the strength of the gravitational field, becomes infinite. Whenever they happen, they pose serious difficulties for physics because they signal a breakdown in the description of the world in mathematical terms. — Lee Smolin

It would of course be a great step forward if we succeeded in combining the gravitational field and the electromagnetic field into a single structure. Only so could the era in theoretical physics inaugurated by Faraday and James Clerk Maxwell be brought to a satisfactory close. — Albert Einstein

Just as there are different types of stars - red and white and brown and blue and dwarf and giant and all that lot - there are different types of Quests, and if we determine what type you face, we shall have a much easier time managing the whole business. We're doing very well. Already we know that Prince Myrrh is an Endgame Object Type W - that's Wonderful, since we have yet to see if he will be any Use in governing. He sleeps suspended in a Theseus-type narrative matrix, however he does seem to have some gravitational pull on events, which is unusual for a T-Type. After all, we still remember him even after all these years. It's far easier to forget something than to remember it. Remembering takes all kinds of magic. No one knows who he is or what he looks like or where to find him, and yet we all know of him. We all know he sleeps in an unopenable box on an unbreakable bower. That's a frightfully strong E.K.T. Field for one little creature! — Catherynne M Valente

My bottom is so big it's got its own gravitational field. — Carol Vorderman

To say that a body or its gravitational field 'bends in space' in its vicinity is the discuss visual space in acoustic terms. — Marshall McLuhan

The bioelectricity of her brain has ceased to function, and as I lay here, the cells are beginning to degenerate and every thought and memory she had is irretrievably fading into nothing. We were like phone towers in concert, reciprocating, each useless without the other, and now I feel like a massive star extending its light, heat, and gravitational pull into a radiant and beautiful universe only to discover that it is singularly without planets, only holding down a vestigial field of cold, dark rocks. — Bryan Way

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. — Stephen Hawking

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. — Werner Heisenberg

The threat of her relapsing had created a strong gravitational field around their little family and was part of the reason he had never left home. He — Reif Larsen

The action of the earth on the stone takes place indirectly. The earth produces in its surroundings a gravitational field, which acts on the stone and produces its motion of fall...The intensity and direction of the field at points farther removed...are thence determined by the law which governs the properties in space of the gravitational fields themselves. — Albert Einstein

Galileo had already made a significant beginning toward a knowledge of the law of motion. He discovered the law of inertia and the law of bodies falling freely in the gravitational field of the earth. — Albert Einstein

Each day, the moon's gravitational field tugs at the earth as it rotates underneath. At CERN, this tiny stress caused the total length of the LEP tunnel to stretch and contract by about a millimeter (one-twenty-fifth of an inch) every day. Not such a big deal in a seventeen-mile-long beam pipe, but enough to cause a tiny fluctuation in the energy of the electrons and positrons - one that was easily detectable by the high-precision instruments. After some initial puzzlement at the daily energy variations, the CERN physicists quickly figured out what was going on. — Sean Carroll

Twisting space-time into knots requires energy on a scale that will not be available within the next several centuries or even millenia-if ever. Even if all the nations of the world were to band together to build a machine that could probe hyperspace, they would ultimately fail. And, as Guth points out, the temperatures necessary to create a baby universe in the laboratory is 1,000 trillion trillion degrees, far in excess of anything available to us. In fact, that temperature is much greater than anything found in the interior of a star. So, although it is possible that Einstein's laws and the laws of quantum theory might allow for time travel, this is not within the capabilities of earthlings like us, who can barely escape the feeble gravitational field of our own planet. While we can marvel at the implications of wormhole research, realizing its potential is strictly reserved for advanced extraterrestrial civilizations. — Michio Kaku

Jupiter's fly-by had been carried out with impeccable precision. Like a ball on a cosmic pool table, Discovery had bounced off the moving gravitational field of Jupiter, and had gained momentum from the impact. Without using any fuel, she had increased her speed by several thousand miles an hour.
Yet there was no violation of the laws of mechanics; Nature always balances her books, and Jupiter had lost exactly as much momentum as Discovery had gained. The planet had been slowed down - but as its mass was a sextillion times greater than the ship's, the change in its orbit was far too small to be detectable. The time had not yet come when Man could leave his mark upon the Solar System. — Arthur C. Clarke

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. — Lee De Forest

Greg's grin returned and I was happy to see it. "See? No vanity. You've lost the ability to care about bullshit that doesn't matter. You're a star, the center of a solar system, with no desire for the planets, asteroids, and moons caught in your gravitational field." "Who wants creepy planets anyway? Planets are amoebas, circling mindlessly in the vacuum of space. They're star stalkers of the worst sort." He continued to look at me like I was a treasure. "Planets are creepy, when you put it like that. — Penny Reid

But Einstein was not the best mathematician around, and others, undeterred by neither the difficulty of the equations nor the war that was ravaging Europe (this was 1916), were able to find solutions. Some of the most important solutions ever found - those that describe the gravitational fields of stars and black holes - were written down by a German officer named Karl Schwarzchild as he lay dying in a field hospital of a skin disease he had picked up in the trenches. — Lee Smolin

[Max Planck] was one of the finest people I have ever known ... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did — Albert Einstein

An observer who is sitting eccentrically on the disc K' is sensible of a force which acts outwards in a radial direction, and which would be interpreted as an effect of inertia (centrifugal force) by an observer who was at rest with respect to the original reference-body K. But the observer on the disc may regard his disc as a reference body which is "at rest"; on the basis of the general principle of relativity he is justified in doing this. The force acting on himself, and in fact on all other bodies which are at rest relative to the disc, he regards as the effect of a gravitational field. — Albert Einstein

A common refrain among theoretical physicists is that the fields of quantum field theory are the "real" entities while the particles they represent are images like the shadows in Plato's cave. As one who did experimental particle physics for forty years before retiring in 2000, I say, "Wait a minute!" No one has ever measured a quantum field, or even a classical electric, magnetic, or gravitational field. No one has ever measured a wavicle, the term used to describe the so-called wavelike properties of a particle. You always measure localized particles. The interference patterns you observe in sending light through slits are not seen in the measurements of individual photons, just in the statistical distributions of an ensemble of many photons. To me, it is the particle that comes closest to reality. But then, I cannot prove it is real either. — Victor J. Stenger

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. — David R. Brower
