What exactly is gravity, and can it be neutralized on earth without using a falling motion?

Answer 1

nature of gravity is a big gray are in physics, and you cannot neutralize it, except by offsetting it with some other force -magnetic field, gravity of another object (not feasible), stong airflow going up.

Answer 2

There are a few competing theories as to what gravity actually is. The most prominent and most accepted is General Relativity. This thoery states that the mass of an object causes space and time to warp around it (much as a bowling ball on a streched out sheet). When other objects move near that warp they are drawn to it. So far as physicists understand, gravity cannot be neutralized. The only way to "neutralize" a force it place a force in the opposite direction with the sam magnitude. The question is, what is the easiest way to do this?

Answer 3

What exactly is the force of gravity? It is one of a particular kind of energy. This may be seen in the writing of, Stephen Hawking in “A Brief History of Time,” page 92, paragraph 3, states; “Like light, gravitational waves carry energy away from the objects that emit them.” The force of gravity is an energy form. It has a particular source of energy, which, if this energy were to no longer exist, then there would be no longer a gravitational field. This is true no matter the size of the mass.

The equation for a gravitational field is part of the physics trilogy - the three equations that describe the existence of our universe. The trilogy is: E = mc2, m = E/c2, and c2 = E/m. The last is that for a gravitational field, or a field of physical time - the two are the same.

Gravitational waves pass through the center of a mass and exist out the other side. We, of the U.S. are being held in place by the mass in and below the Indian Ocean. Likewise it is the mass where we are that keeps the waters of that ocean where they are supposed to be.

This form of energy appears to have the energy value and speed of the value "h", Plank's constant, which means it cannot be stopped in its pregress because there is nothing relatable to it in order to hinder its motion.

There are two short writings, "The Problem and Repair of Relativity" and "Magnetism and Gravity" found at http://360.yahoo.com/noddarc. http://timebones.blogspot.com also has info. on this concept

Answer 4

It is the weakest of the four known fundamental forces (electromagnetic, strong nuclear, and weak nuclear). It is an attractive force between each pair pf particles in the universe. We don't really know why it happens, but it does.

General relativity describes it as a warping of spacetime in the presence of mass.

Physics is obsessed with trying to unify it with the other three forces, and with quantum mechanics. Primary efforts are quantum gravity, superstring theory, and M-brane theory.

There is no known way to neutralize it. It is always attractive. The gravitational force between two masses is independent of everything else in the universe. We have no shield or insulator for it, though I have tried hard to find them. We can compensate for the gravitational force by applying other forces to balance or counter it. In free fall, you still feel the force of earth's gravity. That's what makes you accelerate.

Answer 5

It is very well explained by others above.

We are born to this world with switched-ON state of gravity, and can never experience the absolute null of gravity.

The fact is that it can never be completely neutralized. It will exist in its micro-gravity form (caused by the mass of object trying to neutralize it). Micro-gravity could be traced to orbiting satellite or water-bag supporting a baby (intermittent stages) in the womb of mother - a supernatural fluid (can it be?).

Answer 6

gravity is the force that all bodies with a mass exart upon each other. the earth has a gravitational force of 9.81N.
it is possible to neutralise gravity is there was an object with the same mass as the earth nearby as the gravitational force from that would 'cancell' out the earth gravitational pull.

Answer 7

Sure it is neurtalized by aircraft and magnetism all the time. I'm sure you're looking for a little more complex solution to your question, but keep that in mind.
