We, and everything living on earth, would die, and probably rather quickly. We would become free-floating in space, and even if we could anchor ourselves to bedrock, our atmosphere, water, sand/soil and every other unattached thing would float off into space.
If only that particular force disappeared all the planets would travel off in straight lines away from the Sun. If all gravity disappeared everywhere at the same time, we would no longer have any weight so we would all fly off the surface of the Earth in straight lines, along with the oceans and the atmosphere.
They would move away in straight lines. Eventually they would come into the gravitational influence of another body and this would alter their trajectories.
If sun's gravity suddenly disappears then the planets will stop to revolve around the sun after some time and this duration is equal to the time taken by the light to reach from sun to other planets. For e.g. Time taken by earth to stop revolving and flying off in any direction = Time taken by light to earth from sun = 8 min. 20 seconds Also, planets will start to fly in any direction and they may collapse and in simple words: Solar system will collapse and life will disappear on earth.
The earth's constant orbit around the sun is caused by an equilibrium between two forces - the gravitational pull of the sun, and the earth's velocity acting at a right angle to it. If that gravitational pull was suddenly eliminated, the earth would continue onwards in a straight line.
VGA Planets happened in 1992.
They would travel in a straight line in whatever direction they were moving, and possibly enter into orbit around the galactic center or eventually be captured into orbit around another star.
The same thing that happens every night when the sun disappears...nothing! Gravity on Earth is not dependent on the Sun. But life on Earth is, gravity would be the least of Earth's problems if the Sun dissapeared
Thr body's mass would not change, but its weight would suddenly disappear.
Nothing will happen that concerns you.
If the gravitational field of the sun collapses, the earth is likely to come to an end.
The planets would slowly start to randomly go in directions, eventually colliding into the sun, or other planets.
If the sun would disappear from the centre of the solar system, there would be some reason for it to disappear or there is no other way that the sun can suddenly disappear from the centre. In other ways if there was no sun then there won't be any life on earth, nor there would be any source of light, there would be no heat in the solar system and the temperature of the planets would decrease innumerably, there would be no low tide on the earth or on any other planet, only high tide would be seen.
The motion of the sun will stop because the sun will crush on the earth if the gravitational field of the sun collapses.
If sun's gravity suddenly disappears then the planets will stop to revolve around the sun after some time and this duration is equal to the time taken by the light to reach from sun to other planets. For e.g. Time taken by earth to stop revolving and flying off in any direction = Time taken by light to earth from sun = 8 min. 20 seconds Also, planets will start to fly in any direction and they may collapse and in simple words: Solar system will collapse and life will disappear on earth.
Then the earth, with all of the other planets, will move further away from the sun.
Then earth would be attract and eventually it will disappear.Because if we see it in a logical manner,a BLACKHOLE attracts any other body because of its strong gravitational force.Therefore our earth including our solar system and the other planets around it will eventually disappear.!
Both planets would be destroyed, as the gravitational pull would rip off matter from both planets, and they would be ripped apart.
Then everything in space would fall for the ground due to the massive gravitational force that it is emitting.
If there was suddenly no gravity, the planets would continue to move at the same speed in the current direction they are facing in a straight line until a collision occurs. By the way, if gravity suddenly stopped, the laws of physics would suddenly, drastically change, because gravity is one of the four fundamental interactions.
