Quotes About Gravity

He finds a ramp that leads down to the beach and lets gravity draw him towards sea level, gazing to the south and west. The water is pacific and colorless beneath a hazy sky, the horizon line is barely discernable.

it was more likely that they would lose consciousness from the gee forces first—a relatively painless way to go.

When asked about which scientist he'd like to meet, Neil deGrasse Tyson said, Isaac Newton. No question about it. The smartest person ever to walk the face of this earth. The man was connected to the universe in spooky ways. He discovered the laws of motion, the laws of gravity, the laws of optics. Then he turned 26.

Matter tells space how to curve; space tells matter how to move.?

Without a doubt, the most spectacular way to die in space is to fall into a black hole.

Dark energy is a mysterious pressure in the vacuum of space that acts in the opposite direction of gravity, forcing the universe to expand faster than it otherwise would.

A bullet fired level from a gun will hit ground at same time as a bullet dropped from the same height. Do the Physics.

Dark matter is a mysterious substance that has gravity but does not interact with light in any known way.

If all mass has gravity, does all gravity have mass? We don't know. Maybe there's nothing wrong with the matter, and it's the gravity we don't understand.

If all mass has gravity, does all gravity have mass? We don't know.

Until Sir Isaac Newton wrote down the universal law of gravitation, nobody had any reason to presume that the laws of physics at home were the same as everywhere else in the universe. Earth had earthly things going on and the heavens had heavenly things going on.

Ordinary matter is what we are all made of. It has gravity and interacts with light. Dark matter is a mysterious substance that has gravity but does not interact with light in any known way. Dark energy is a mysterious pressure in the vacuum of space that acts in the opposite direction of gravity, forcing the universe to expand faster than it otherwise would.

Ordinary matter is what we are all made of. It has gravity and interacts with light. Dark matter is a mysterious substance that has gravity but does not interact with light in any known way. Dark energy is a mysterious pressure in the vacuum of space that acts in the

So lambda's sole job was to oppose gravity within Einstein's model, keeping the universe in balance, resisting the natural tendency for gravity to pull the whole universe into one giant mass.

The exact orbit of Earth is controlled by the Sun's mass and the mass of all remaining planets. An object's mass and its distance is all we need to know to completely determine the effects of its gravity on Earth.

For ordinary household gravity, Newton's law works just fine. It got us to the Moon and returned us safely to Earth in 1969. For black holes and the large-scale structure of the universe, we need general relativity.

where there is mass there is gravity. And where there is gravity there is curved space, according to Einstein's general theory of relativity. And where space is curved it can mimic the curvature of an ordinary glass lens and alter the pathways of light that pass through.

From galaxy to galaxy and from cluster to cluster, the discrepancy between the mass tallied from visible objects and the objects' mass estimated from total gravity ranges from a factor of a few up to (in some cases) a factor of many hundreds. Across the universe, the discrepancy averages to a factor of six: cosmic dark matter has about six times the total gravity of all the visible matter.

On the equator, where centrifugal forces are greatest, a 150-pound person will be a slender 149 pounds 14 ounces.

Gravity is a marvelous force, but a troubling one.

If you feed a black hole, its event horizon (that boundary beyond which light cannot escape) grows in direct proportion to its mass, which means that as a black hole's mass increases, the average density within its event horizon actually decreases. Meanwhile, as far as we can tell from our equations, the material content of a black hole has collapsed to a single point of near-infinite density at its center.

In our own solar system, for example, everything that is not the Sun adds up to less than one fifth of one percent of the Sun's mass.

The actual recipe for the asteroid belt? Take a mere 2.5 percent of the Moon's mass (itself, just 1/81 the mass of Earth), crush it into thousands of assorted pieces, but make sure that three-quarters of the mass is contained in just four asteroids. Then spread them all across a 100-million-mile-wide belt that tracks along a 1.5-billion-mile path around the Sun.

If a particle can fall into a black hole, it can come out of a white hole.
