What is gravity?

Question

everyone talkes about space travel and exploration, but one thing has not truly been defined, Gravity. If an antigravity device is invented, then it would take less fuel and resources to reach and explore space. And to be able to colonize other planets or moons.

Answer 1

EASY! it is attraction among ALL matter and energy in UNIVERSE

it is theorically made of gravion, a particle of attraction!

according to NEWTON, it is a force!! F=Gmm/r2

according to EINSTEIN, it is distortion of space causing object to spin around and not leave!!!

Answer 2

I agree with most of the theory that has been mentioned concerning gravity being the warping of space by mass. As to antigravity; the wikipedia entry to that subject is by it's own admission somewhat controversial. As to electro or ionic effects there is a distinction between electromagnetic effects and gravitational effects. Confusing what is being discussed by calling an electromagnetic effect a gravitational effect does not advance research, however there is the possibility that electro arc jets and ionic drives have a purpose in space travel, but it should be properly defined. As to Gravitational Propulsion, or the warping of space (as mass does) in order to propel an object through space by it's inter dimensional interactions (or geometrical gravitational interactions in space) ; that holds considerable promise. Another recent experiment in Gyroscopic/Gravitational interactions has been performed with repeated results under one ESA research project and it is mentioned in the above mentioned wikipedia entry for antigravity, right below a statement by NASA that says it is unlikely. The main problem may be in defining what scientists are really researching, and not confusing the effects themselves with other effects.

Answer 3

In physics, gravitation or gravity is the tendency of objects with mass to accelerate toward each other. Gravitation is one of the four fundamental interactions in nature, the other three being the electromagnetic force, the weak nuclear force, and the strong nuclear force. Gravitation is the weakest of these interactions, but acts over great distances and is always attractive. In classical mechanics, gravitation arises out of the force of gravity (which is often used as a synonym for gravitation). In general relativity, gravitation arises out of spacetime being curved by the presence of mass, and is not a force. In quantum gravity theories, either the graviton is the postulated carrier of the gravitational force[1], or time-space itself is envisioned as discrete in nature, or both.

The gravitational attraction of the Earth endows objects with weight and causes them to fall to the ground when dropped (the earth also moves toward the object, but this is so small the effects are negligible at best ). Moreover, gravitation is the reason for the very existence of the earth, the sun and other celestial bodies; without it matter would not have coalesced into these bodies and life as we know it would not exist. Gravitation is also responsible for keeping the earth and the other planets in their orbits around the sun, the moon in its orbit around the earth, for the formation of tides, and for various other natural phenomena that we observe.

Answer 4

Gravity is the downward flow of electrons from our upper grid to the earths grounds and everything with an electron flows naturally to its ground. There are just so many examples in nature of the proofs that I am surprised by the anount of folks who have not observed the planet and connected the dots. Storms run along a path that leads to a ground,tornados run toward a ground,which is the answer to tornado alley phenomena.Hurricanes are so large because the spin of the main grid nodes in the ocean cannot find a ground,till they come on shore.If ther wasnt a frequency surrounding this planet,we would not have snowflakes.Look up Dr. Emotos work on cymatics where he demonstrates snowflake production with frequency.And again gravity is electrons (aetheric force inbound from sun) flowing towards the earths grounds.Oh ,and that flow of electrons/aetheric force flows to grounds and heats the magma on this here earth,so more grid energy,more magma heating. Simple and sweet. And if you are paying attention to my words,you may have processed that its the grid perturbed heating the planet,not the greenhouse gases.Man is not the cause of global warming. Period.

Answer 5

Gravity is nothing but the short for "Gravitational force", in which essentially, one of the bodies involved should be the earth.
Gravity is conceptually defined as the force exerted by any two bodies in the universe.. it may just be me and u, even if we are in two diff sides of the universe. The force will be negligible, but it will be there.

Numerically, F = Gmm'/r(2)

where F = force of gravity
G = Grav const 6.67 x 10(*-11)
m, m' >> masses of the two bodies being discussed
r >> distance between them.


The force will exist between u and ur computer, the earth and the stars.. practically everything.

Answer 6

Gravity is one of the fundamental forces of physics.

You are sort of right to expect an anti-gravity, but there is no reason there should be - is there?

The fundamental forces are: electromagnetic, strong and weak nuclear, and gravity.

But of course, this is only the best current model for the universe that our science can provide. If you have evidence of a better model, please publish.

Answer 7

the attraction due to gravitation that the Earth or another celestial body exerts on an object on or near its surface

Answer 8

Too heavy a question to be answered at this point in time.

Answer 9

there are some things to take care of here on earth before any of that can happen

Answer 10

We are >static-cling< in the great dryer of high speed physics.
