The only three methods of creating a microgravity environment are to travel far enough into deep space so as to reduce the effect of gravity by attenuation, by falling, and by orbiting a planet. The terms weightlessness and Zero-G refer to this same environment. The first method is the simplest in conception, but requires you to travel an enormous distance, rendering it most imprac… (More on Microgravity)
