can we get rid of gravititional power while standing on earth?

As far as I know, they are still not sure as to what creates gravitational force. If they determine the source, one might negate it to experience zero gravity anywhere.

HOW TO LIVE ON planet earth WITHOUT decimating it !

Life on earth will end before that.\nBecause sun before turning off will create havoc to earth's life supporting system.

decrease potential energy.....through physical factors like friction....

No. If the Earth suddenly came to a stop and started orbiting the sun in the opposite direction it would probably kill us all. Inertia is not your friend.

No, you cannot simply remove gravity from a specific place.\nHoweverkm you can remove the sensation of gravity (for example, when something is free-falling), but gravity is still very much there effecting the object.

Zero gravity is impossible on earth.  Actually, zero gravity is impossible anywhere.  Gravity acts through millions of light-years, holding galaxy groups together, so there's no way that you can eliminate gravity this close to a major mass like the earth.\n\nHowever - you CAN have a situation that is mathematically and physically equivalent to zero gravity, and that is free fall.  Jump on a trampoline, you'll spend a few fractions of a second in free fall, which is just like zero-G.  NASA does it with the Vomit Comet, which is a modified KC-135 aircraft that flies in parabolic paths to give astronauts-in-training a freefall experience.   NASA also has a (mis-named) test site called the "Zero Gravity Research Facility."   See the last link, below, for more info about this 500-foot tall drop test site.

No effect. They're so far away their magnetic and gravitational fields have only the most infinitesimal influence on the Earth.

I think it is nature's way.\nWhen things in nature get too out of balance, at some point it turns around and evens out. I would like to see the earth's envionment restored at any cost. We are not as important as we would like to believe.

Know what? The answer is "yes", we could and would change the rotation of Earth. If every wheeled vehicle simultaneously accelerated eastward, Earth's rotation would slow a bit, and if they accelerated westward, it would speed up.  You can calculate the amount, it's actually a pretty simple physics application, starting with say 1 billion 3000-pound vehicles, say all of them spread out along the equator, all accelerate at 1 G, and given the mass of Earth, which is easily look-up-able.  Of course, we're probably talking a change of only picoseconds or maybe only femtoseconds per day, but it is a true and calculatable, even theoretically testable change.  Also note that friction, both during the mass-acceleration and especially once everybody hits the brakes, will impart the opposite force, resulting in a zero net gain.  In other words, a temporary, but no permanent change in rotational speed is possible under this scheme, unless somehow the vehicles, while accelerating, attain a speed sufficient to launch them into space at escape velocity.  Then their effect on Earth's rotation can remain behind as permanent.\n\nInteresting thought, huh?\n\n[Below added after reading the 2 posts below]\n\nOkay, I took a crack at the math, thank you wikipedia for the definitions and equations:\n\n1 billion cars of average of 1000 kilograms each, lined up along the equator accelerate simultaneously from a dead stop at a rate of 1G (32ft/sec^2).  Their combined net torque looks to be a force of 10^12 kg, approximately equal to 10^13 Newtons. If I understand wiki correctly, the change in the speed of the rotation of Earth (in radians per second) will be the previously-calculated torque divided by the moment of inertia of Earth, which should be:\n\n(2/5)(6*10^24)(13*10^6)\n\n so the change in speed will be:\n\n10^13/[(2/5)(6*10^24)(13*10^6)] radians per second =\n0.3*10^ -18 radians per second that the cars accelerate at 1G.  If they can do that for just 10 seconds, the change in Earth's rotation would total  3*10^ -18 radians per second, or .26*10^ -12 radians per day.  Earth's rotation is about 24*10^12 times faster, so I think altogether that works out to a net change of 3.6*10^ -9, or 3.6 picoseconds change per day in Earth's rotation?  Tho I pretty sure I've made at least a couple of mistakes along the way, I gotta love how that agrees with my original guesstimate above.\n\nJeeez, it's 2 in the morn - I really DO need to get a life...

The planets in our system are way, way too small to do anything like this. It would take something with the density of a black hole (or perhaps just a neutron star) to do something like this.

kfawl has the most accurate answer... that although we can realistically simulate zero gravity, and the only real way to do that is to use the aforementioned Vomit Comit - I mean we can't realistically put someone at the center of the earth, and sure, if you put someone in an elevator and cut the cords, for some time, the person will experience weightlessness - not that they'll notice since they'll be thinking of their impending death.\n\nAnd you can even go in orbit and although it will feel like you're in a zero G environment, logically thinking - the earth is gigantc and you've not travelled very far from it - how can there suddenly be no gravity? Because the shuttle is actually falling, but travelling sideways so fast that it keeps "missing the earth". This also applies to sattelites or anything orbit. The only reason Earth doesn't fall into the sun is because it is rotating so fast, it "keeps missing the sun."\n\nAnd although its been said that it is impossible to really be in a zero g environment, I believe if you go out far enough, the pull of the planets or stars will be so negligable, that for all intents and purposes, you'll be in a zero-g environment,

In order to combat gravity, we would need to be able to understand what it is. At the moment, we don't. If we did, it still would be a tall order to mess with the field of a whole planet. Assuming we could "stabilize" gravity at the quantum level, whatever device we invented to do this would undoubtedly require huge amounts of energy.\n\nA much easier method would be to install a system of shock absorbers and hydraulics underneath the floor. Controlled by a computer, these could make up for some weakenings in the field and simulate to the human feet an equal field. This wouldn't actually solve the problem, just treat the syptoms. The air pressure of the cabin could also be increased to press our feet down on the ground more, but if we mess with this too much, we will implode. Also, there is the idea of placing a large verticaly aligned doughnut-shaped cabin to produce "gravity" in the form of centrifugal force, but this would be extremely impractical and require a lot of digging. I hope this helps, because until we have Artificial Gravity, there isn't really a lot that can be done. Cool question, though.

pause time.\nu can do the rest of the powers with just that power

if gravity was absent, teh earth would have moved away from sun...it would be dark, the plants would not grow, we would die out of cold. we maynot even be able to stand in oneplace.....

I do not get Popular Science, but I have heard proposals to put a sunshade in space to reduce the solar energy reaching Earth and so solve the global warming problem. This would definitely work, but I think it is too soon to proceed. What if we cool the Earth too much? Who would be to blame? If NASA put up the shade and Finland or some other country had a bad winter, would the US have to pay damages? It would be a political nightmare. With great power comes great responsibility. If we can really control the weather, then if somebody doesn't like the weather is our fault. Do we want to take that responsibility? Yes we do if massive bad stuff has already happened that can be 100% blamed on global warming, but when was the last time the world agreed 100% on anything? Even if sea levels rise 100 feet and we put the shade in place, somebody in the world would sue us anyway, but if we put it up now, before sea levels rise at all, EVERYBODY will sue us!

Probably won't work.  If you assume 10 billion people with an average weight of 150 lbs, the mass of the earth is about 10,000,000,000,000 (10^13) times greater.  If everyone jumped up and down, even on the same side of the Earth, it wouldn't affect the earth's momentum or motion in it's orbit.  The acceleration applied by the mass of people is just too small.  Think of it as being in the 13th decimal place(0.0000000000001), it's essentially unnoticeable.
