What use said is not even close to true. In order to get a ‘gravity’ chamber, “all” they need to do is make a chamber that moved in a circular motion, such that a centipetal force was created.The term gravity as we no it, while lifting, is actually a reaction from the floor caused by the Earth’s gravity. The concept of the gravity chamber has to do with preceived weight, not actual weight.
Dainon is wrong. Gravity is an attractive force that is in no way different from acceleration. In fact, acceleration is measured in "G"s with one G being equal to the gravitational force on the surface of the earth. Gravity is projected by a particle called a graviton, which is a force particle, like those that transmit the weak force, which causes nuclear decay, and the strong force, which holds atomic nuclei togather. Gravity is unique in a number of ways, in that it is actually weak, but can travel long distances, can actually affect time (from the position of an observer in a strong field)and is proportional to the distance from the center of the mass emiting it. There is nothing “coming from the floor”. Gravity falls off as the inverse square of the distance, so if you move twice as far from the source, the force strength is quartered. This would mean that perhaps a better way to create out gravity training chamber would be to put it above Jupiter, moving it closer and farther away as training periodization dictates. also, you could just have one barbell, and move your gym to change the weight.
