Gravitational Force Quotes

The earth is moved from its position by the weight of a tiny bird resting upon it.

Dark energy is incredibly strange, but actually it makes sense to me that it went unnoticed, because dark energy has no effect on daily life, or even inside our solar system.

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.

We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?

If you put Earth out beyond Neptune, you wouldn't be able to call it a planet because it couldn't clear its zone.

I am deeply impressed with the way dark matter has explained cosmological observations.

I am sitting here 93 million miles from the sun on a rounded rock which is spinning at the rate of 1000 miles an hour... and my head pointing down into space with nothing between me and infinity but something called gravity which I can't even understand, and which you can't even buy any place so as to have some stored away for a gravityless day.

M-theory is the unified theory Einstein was hoping to find.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

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.

We can summarize electricity, magnetism and gravity into equations one inch long, and that's the power of field theory. And so I said to myself: I will create a field theory of strings. And when I did it one day, it was incredible, realizing that on a sheet of paper I can write down an equation which summarized almost all physical knowledge.

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.

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

Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.

Gravity is a mysterious carriage of the body invented to cover the defects of the mind.

The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity.

Every particle of matter is attracted by or gravitates to every other particle of matter with a force inversely proportional to the squares of their distances.

It's physics. Pure physics, I'm falling fast and faster still. So fall with me. Fall down with me. And stay.

A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory.

My work indicated that if we consider smaller and smaller black holes, at some stage, the properties of black holes become indistinguishable from those of elementary particles.

I have not been able to discover the cause of those properties of gravity from phenomena, and I frame no hypotheses; for whatever is not deduced from the phenomena is to be called a hypothesis, and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.

You think Earth's gravity is really something when you're climbing the stairs. But, as far as physics goes, it is a pipsqueak, infinitesimal, tiny little effect.

Among the questions we have in mind: dark matter, antimatter, and matter symmetry.

I was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me: "If a person falls freely he will not feel his own weight." I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

How does gravity work? And if it were to cease suddenly, would certain restaurants still require a jacket?
