How can we create an area of zero gravity on Earth?

Question

For training the astronauts and space travelers and for performing experiments relating to zero gravity how do we create conditions?

Answer 1

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.

However - 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.

Answer 2

Zero Gravity On Earth

Answer 3

a free fall in a controlled manner can create zero gravity on earth.astronauts and cosmonauts r trainned on earth for zero gravity. one way can be a lift dropped free fall from a very tall building without any stoppages will give a zero gravity experience to the one inside the lift.

Answer 4

Attaining zero gravity ON Earth is impossible due the incredible amount of mass that our Earth has to produce it's gravity.

Yes,it is possible , inside the many chambers zero gravity effect is created . Moreover, it is also possible with the help airplanes.Many airplanes have been designed for this purpose only but this effect is not long lasting . This effect works only for few seconds either in a plane or in a chamber.........Hope it will help u................

Answer 6

You must know that gravity manifests some properties of acceleration with respect to surrounding. Thus zero gravity means zero acceleration with respect to other surrounding objects thus by creating two objects of equal acceleration, zero gravity can artificially be created. And acceleration due to gravity is same for each object. In short leave astronauts in a freely falling plane.

Answer 7

The Vomit Comet suggestion would indeed provide weightless conditions, but not a "zero-gravity" condition. True "zero gravity" is not possible, as the effects of gravity from a single massive body are felt (even to a small degree) everywhere in the universe. The have zero gravity, there would have to be no mass in the universe.

Answer 8

Tanks filled with water create Zero gravity conditions. Astronauts train in the water tanks.

Answer 9

They train by going in parabolic arcs in airplanes. At the top of the parabola, gravity's effect is minimal.
We can't really create an area of zero gravity but magnets can overcome the force of gravity to make an object "hover."

Answer 10

One method NASA uses to train astronauts for zero gravity is to use swimming pools. While not identical to zero gravity in air because the water is so much denser, it provides a very close simulation. The advantage with this method is that the astronauts are able to do tasks that can take hours. The parabolic flight is limited to a few minutes.
