Loss of Gravity?

Question

What would happen if the world suddenly lost its gravatiational pull? What everything just float away?..

Answer 1

the Earth cannot lose its gravity it is determined by the size of an object that attracts things to it.

its not like a magnet that could lose its attraction

Everything creates gravity, even we do to the things around us its just so miniscule that you would never ever know.

However, if it was possible then yes all the atmosphere would disappear and we would all float away after being suffocated from lack of oxygen.

Answer 2

If the earth suddenly lost its gravitational pull we wouldn't just float away, we'd be thrown away.

The earth is spinning on its axis quite rapidly and everything on the surface of the earth is spinning with it. If we spin an object round our heads on a piece of string it will continue to spin as long as the string doesn't break but if it does it will shoot off at a tangent and that is what would happen to us.

The moon would also shoot off at a tangent and, if the earth lost its gravitational force, presumably the sun would lose it as well. The earth would then fly off into space and the sun would disintegrate as the gases it's made of would no longer be held together by gravity.

Hopefully it won't happen!

Answer 3

If gravity on all the celestial objects (the curving of the spacetime fabric) is gone, then that means the galaxies would disintegrate and crumble into dust. The matter/energy distribution would tend to zero. without mass, time has no meaning. So time tends to stop and matter cease to exist. With no time, space is meaningless. This leads to absurdum. So gravity is very fundamental to the existence of mass!! Gravity is not a seperate effect. It is due to the very existence of the mass itself and therefore time and space. It is impossible to stop a mass from creating gravity.

Infact gravity is ONLY an illusion. It is actually the bending of the spacetime continuum. When you are in free fall you float. You dont feel gravity! When we are floating, we are in an inertial frame. It is only when you are on the ground, you feel someting is pulling you down. Why are we falling as observed by the person on the ground ? The short answer is that space and time are closely related together. The presence of a mass, bends the spacetime fabric around it. We are just following the gedesics of the spacetime curvature as we are falling from a height. That is why we dont feel any effect of gravity. When we are in the ground, we are pulled towards the center of the earth due to the curved spacetime. The surface of the earth resists this motion in space and perceived as gravity. In an inertial frame, we are not obligated to move in space, but we are moving in time. In a curved spacetime (which causes gravity) , movement in time compells us to move in space for us to remain inertial !!.

Answer 4

This cannot happen as every body having mass possesses gravity. The more the mass... the more the gravitational force. But, if this may really happen, nothing would change. The atmosphere would go nowhere, we would be able to walk anywhere, we could dig through water.
I am saying this, because, there will be no force that the atmosphere would be attracted. The heaviest thing would be easy to handle. You would be able to do all kinds of marvels.

I do not quite agree with that, we would be thrown away, as even other force...i don't remember the name would exist.

Answer 5

The Earth (and anything else that is spinning) would be ripped apart, throwing debris across the galaxy. Stars would begin an unending rapid expansion, growing less dense all the time.

Gravity is the main thing holding Earth together, and the only thing holding stars together.

All humans would die very quickly if you turned off gravity.

Answer 6

The world dont have a G Pull.

Answer 7

For the record, I hereby retain rights to the science fiction story I am about to outline.

God decides that the universe has had enough time to operate under the physical laws He created along with the universe, time, and space. At 3pm Pacific Standard Time (earth), January 3, 2014, the gravitational force every mass now experiences with every other mass will cease to exist. All other physical laws will continue unchanged. Every mass will continue to move and accelerate according to the sum of all forces on it. One of those forces will suddenly be reduced to zero.

The motion of celestial bodies is affected only by gravity. Since matter is, on average, electrically neutral, the electrostatic force at a distance is zero. Heavenly bodies will cease orbital movement, and will instead continue to move in whatever direction they were moving at that instant and continue in that direction forever, until they collide with something. The overall gravitational attraction of the universe will cease restraining the expansion of the universe, and it will instead continue to expand at whatever rate it was expanding at the time. The Hubble Constant suddenly becomes meaningless.

Closer to home, earth would cease orbiting the sun and just continue on a linear tangent path. In a year, its distance from the sun would increase by about the circumference of its orbit, about 4 times its present distance. Incident solar energy would drop by a factor of two to the fourth power, or 16. Solar power and all its direct derivatives (wind, hydro) would become useless. Hydro had already become useless, since there's no gravity to draw the water through the turbines. Wind was also useless, since the atmosphere drifted away from earth with no gravity to hold it in place. We still have nuclear and some geothermal, but we stopped using fossil fuels, since our remaining oxygen is far too precious to waste on burning.

We have some time to plan and prepare, so human society begins to deemphasize its more trivial pursuits and works toward building self-contained, self-sustainable colonies, with domes to retain atmosphere, and everything tied down so it won't drift away. Uranium mining accelerates, as does construction and deployment of nuclear reactors. Geologists devote themselves to figuring out whether the earth will hold together without gravity, of whether it will break apart. Physicists work furiously to calculate all the implications. How long will the sun sustain its fusion reaction without gravity? Raising animals for food is phased out, and agriculture concentrates on maximum grain production and packaging it for maximum longevity, like granola bars in sealed packages.

People realize that there is no way they can build enough infrastructure to sustain earth's present population, much less continued population growth. They realize that decisions will need to be made about who lives and who dies. Suddenly, the value of individual contribution to society will determine not only their economic wealth, but their very life.

Some will realize that their ignorance and rejection of God was foolish and short-sighted, will repent, and will devote themselves to knowing God and obeying Him, and following His direction. Others will succumb to the "eat, drink, and be merry; for tomorrow we die" philosophy. It will be the best of times. It will be the worst of times.

Answer 8

Without gravity binding everything together there would quite literally be nothing, the whole universe would revert back to cosmic dust as everything flew apart!

Answer 9

It wouldn't happen, but it would be freeking col to watch, id like to see what happens to all the water, would the sea just float off as one big hole or would it break up? well actually it would just freeze, but thats no fun

Answer 10

Ask Jordan - she's been defying gravity for years
