Quotes About Gravity

fuerzas gravitatorias de Newton, por las que dos objetos se atraen mutuamente de manera directamente proporcional a su masa e inversamente proporcional a la distancia que los separa.

This phenomenon, called time dilation, leads to what is known as the twin paradox.

His new idea was published that month in what became yet another seminal Einstein paper, "Cosmological Considerations in the General Theory of Relativity." On the surface, it did indeed seem to be based on a crazy notion: space has no borders because gravity bends it back on itself.

His head-snapping insight was that gravity could be defined as the curvature of spacetime, and thus it could be represented by a metric tensor.

While others continued to develop quantum mechanics, undaunted by the uncertainties at its core, Einstein persevered in his lonelier quest for a more complete explanation of the universe—a unified field theory that would tie together electricity and magnetism and gravity and quantum mechanics.

Einstein's goal as he pursued his general theory of relativity was to find the mathematical equations describing two complementary processes: 1. How a gravitational field acts on matter, telling it how to move. 2. And in turn, how matter generates gravitational fields in spacetime, telling it how to curve. His head-snapping insight was that gravity could be defined as the curvature of spacetime, and thus it could be represented by a metric tensor. For more than three years he

A person "at rest" on the equator is actually spinning with the earth's rotation at 1,040 miles per hour and orbiting with the earth around the sun at 67,000 miles per hour.

was sitting in a chair in the patent office at Bern when all of a sudden a thought occurred to me," he recalled. "If a person falls freely, he will not feel his own weight." That realization, which "startled" him, launched him on an arduous eight-year effort to generalize his special theory of relativity and "impelled me toward a theory of gravitation."16 Later, he would grandly call it "the happiest* thought in my life.

The curving and rippling fabric of spacetime explained gravity, its equivalence to acceleration, and, Einstein asserted, the general relativity of all forms of motion.

According to that theory, clocks in stronger gravitational fields run more slowly than those in weaker gravity.

The central idea of general relativity is that gravity arises from the curvature of spacetime

A man must support his own weight, no matter how much money or power he has; that is the law of gravity.

Such days of autumnal decline hold a strange mystery which adds to the gravity of all our moods. Every step that Time takes imprints upon the fields as they grow bare and brown...

Such days of autumnal decline hold a strange mystery which adds to the gravity of all our moods.

Why do you never see elephants hiding up in trees? Because they're really good at it. I'm reading an anti-gravity book. I can't put it down!

To the person who stole my place in line: I'm after you now. What is the center of gravity? The letter "v"! Why did the quiz show give away $10,000 plus one banana? They wanted the prize to have appeal. What do you call corn that joins the army? A kernel.

Economics is like gravity: Ignore it and you will be in for some rude surprises.

She used her heart to love him, not her head, not her words and not her thoughts or ideas or feelings or any other vehicle or object or device people use to deliver love or love-like things. She used her heart, as a physical transmitter of love, and what came out of it was no more voluntary than gravity or time or time travel or the laws of fictional science itself.

All of her heart, a meaningless phrase, but correct and precise, too. She used her heart to love him, not her head, and not her words and not her thoughts or ideas or feelings or any other vehicle or object or device people use to deliver love or love-like things. She used her heart, as a physical transmitter of love, and what came out of it was no more voluntary than gravity or time or time travel or the laws of fictional science itself.

But no one laughed. No one would. The universe, I'd learned, was never, ever kidding.

What was the joke the paratroops used in jump school? It's not the fall that kills you, it's the sudden stop.

Mr. Tacker, who from his great experience in the performance of funerals, would have made an excellent pantomime actor, winked at Mrs. Gamp without at all disturbing the gravity of his countenance...

Law of the Workshop: Any tool, when dropped, will roll to the least accessible corner.

Football players throw a 3 pound ball in the air, but cheerleaders throw a 100 pound girl in the air and catch her.
