Is there a room in the world where you can turn off gravity?

Answer 1

You can turn off the effects of gravity in a lift. Just disable the emergency brake on the lift, and cut the cables. Once you get into freefall you'll float above the lift floor... temporarily before the lift crashes to the bottom and crush you.

So find a really tall building. Otherwise, doing the same freefall with an aeroplane does the same trick without the same crushing consequences. Just find a good stunt pilot.

Answer 2

The only valid location for "turning off" gravity is where the force vectors associated with gravity add up to zero. Hypothetically, that would be at or near the centre of the Earth, where the matter of the planet is pulling in all directions.

The other answers can make it seem like gravity is turned off, but in reality, gravity is still there, just masked by the fact that you and your surroundings are falling at the same rate. This applies to earth orbit as well. There is the sensation of weightlessness, but gravity is still present. (Likewise, absent of air resistance, a parachute diver is weightless in freefall as he or she is not pushing against anything, but gravity is still pulling the diver down.)

Answer 3

Yes, the Vomit Comet

Weightlessness inside the Vomit CometThe Vomit Comet is the nickname given to the aircraft used by NASA's Reduced Gravity Research Program since 1973. NASA prefers the nickname "Weightless Wonder," for public relations reasons. The plane makes parabolic flight paths, thus allowing the occupants to experience reduced gravity during the parabola. By modifying the flight path, any value for the apparent gravity may be produced. In general it is used to train astronauts in zero-g maneuvers, giving them about 25 seconds of weightlessness out of 65 seconds of flight. This often produces nausea due to airsickness, especially in novices. Astronauts training for the moon missions practiced walking in 1/6 gravity in the aircraft.

Twin KC-135 Stratotankers were used until December 2004 and have since been retired. One, a converted Boeing 707 known as NASA 930 was also used for filming scenes involving weightlessness in the movie Apollo 13; that aircraft was retired in 2000 and is now on display at Ellington Field, near the Johnson Space Center. It's estimated to have flown over 58,000 parabolas. The other made its final flight on October 29, 2004, and is permanently stored in the AMARC storage facility in Arizona.

In 2005, NASA replaced the aircraft with a McDonnell Douglas C-9 that was formerly owned by KLM Airlines and the United States Navy [1]. The same year, the Zero-Gravity Corporation, a commercial parabolic flight operator which offers parabolic flight to both researchers and adventure tourists, began flying parabolic flights for NASA with Boeing 727 jets.

According to Reduced Gravity Research Program director John Yaniec, anxiety contributes most to passenger's airsickness. Yaniec gives a rough estimate that of passengers, "one third [become] violently ill, the next third moderately ill, and the final third not at all."

A similar variant to the NASA's Vomit Comet Program is the ESA's A300 Zero-G Program.

Answer 4

There are drop towers where things can fall in a vacuum for a few seconds or the famous diving plane trick. It should be noted that neither of these turn off gravity, you are just dropping the floor away as fast as you are falling so you never get any closer to it.

Answer 5

Yes, but not really in the world, rather in the belly of a plane thousands of feet in the air doing a nosedive back to Earth. In those few seconds, there is zero gravity. That's how NASA train astronauts and that's how they filmed Apollo 13! As far as I know, that's the only worldly way to achieve it.

Answer 6

I saw something on the net where a frog was suspended weightlessly in a chamber of some description. Don't know if that was zero gravity or some method of repulsion like two magnets repelling each other. Poor froggy though, bet that done his head right in.

Answer 7

Astronauts use zero gravity in the vomit comet, its when an aeroplane drop altitude very suddenly and induce zero gravity for 30 seconds, like being on the worlds biggest rolla coster.

Answer 8

N.A.S.A space station in america has a non gravity room. It's a vivid memory when the visialised it on the new's it looks cool. it would feel quality.

Answer 9

NO! Virtually you can with some fun places, like the 0G simulator.
But you cannot turn gravity off for real, it is to strong.

Answer 10

I think the NASA has created one such room for doing experiments related to space where there is no gravity.
