Since the Theory came more close to practical, nd the only problem is the amount of electromagnetic energy to create an anti-gravity room on earth, then how much energy are we talking about?
NASA trains the astronauts by taking them real high in a plane then dive down them, that they feel an apparent effect of weightlessness, to get them used to zero gs.
Since its practical to create an anti-gravity room, by lets say 5 m^3 dimension, How much ENERGY are we talking about that they do'nt even try to build it? or even if they are, am not aware of.
tnx fellas

Just Fly: Hun, u just made a huge mistake... 2 objects (no matter what) lets say Feather and an apple, in a frictionless space, with no air resistance, FALL at the same time, since the g is the same on both, in our case, 9.81...
It is possible to cancel the gravity of a room, by a huge amount of electromagnetic force. and the amount for me is unknown.

Just Fly: (Since there is nowhere with no air. Certainly the falling speed will be different.) Sure there is place with absence of air. galileo studied the idealized situation of motion in the absence of air-we call it VACUME among the friends.
The ancient Greek scientist and philosopher Aristtotle asserted that heavier objects "Fall faster" than do light objects. well of course his claim was based on casual observations and on what he thought "should" happen rather than on actual experiments. Galileo in 17th cen. was the first to challenge Aristotle and to put his assertion to a rigorous experimental test. The storyof Galileo dropping different weights from the leaning bell tower at the cathedral in Paris is well known, although historians can not confirm its truth. But the bell towers were common in the Italy, so he had ample opportunity to make the observation.

The observation showed that objects hit the ground in slight differences as due to air resistance. He then formulated a general conclusion for an idealized situation of motion in a VACUME. In doing so, Galileo developed a model of motion in absence of Air resistance that could only be approximated by any real object. It was Galileo's innovative use of experiments, models and mathematics that made him the first "modern"scentist.
summerise: :P
1.) Two objects dropped from the same height will, if air resistance can be neglected, hit the ground at the same time and with the same speed.
2.) Consequently, any two objects in free fall, regardless of their mass,have the same acceleration (free fall).
3.) g is not galled "gravity". Gravity is a force, not an acceleration. g is the acceleration due to gravity.
4.) g,by definition,is always (+). There will never be a problem that will use (-) value for g. But u say objects fall when you release them, rather than rise, so how can g be (+)?

Arkalius: Nice approach to a problem. But what other force(s) do u think that can be more realistic nd logical to gravitational than EM forces? u mean there is no force or energy that we can use to cancel out a gravity in a small portion?
