what is gravity and why is there no opposite of gravity?

Question

most scientific phenomena have opposites,like electricity,or magnetism,why not gravity.
einstein died trying to find the answer .steven hawking does'nt know the answer.
do you?

there is no answer to this question.
science simply does not know.
some answers were way off beam and missed the point.like the hole caused by the force of a falling object.totally different issue.no cogent explanations deserving of 10 points.

Answer 2

They overlooked the obvious. Nobody can accurately say what gravity is or where it comes from. The opposite of gravity is not repellent forces, but merely zero or lack of gravity, aka weightlessness. There could possibly be a repellent force somewhere in the universe, but man has not encountered it so far, and probably won't, since it would repel us away from it, being the opposite of the theoretical black hole.

Answer 3

Gravity is a force that tends to pull everything to the center of the earth. Lack of gravitational force in space translates into weightlessness as in space the person or thing is out of the force of the earths gravitational pull.

Answer 4

the opposite force of gravity is
that, which acts on the object.
(for example, a coconut free falls to ground. Then the force ground suffers is opposite force of gravity. Due to that, the
ground may occur a hole..etc)

Answer 5

Gravity isn't a stress contained in the commonly used experience yet is the end results of the geometry of area. the different, if it exists, is an section distortion contained in the different route to the conventional distortion route.

Answer 6

Since gravity relates to accleration, which has direction, gravity has direction. So the opposite of gravity in one direction is gravity in the other direction. (Einstein would have approved, believe me)
