In practice a person has extension so each part of their body will experience a net force and their body will expand slightly. The same person out in space far away from any gravitational masses will not expand. On the other hand, it is true for a person inside a hollow sphere, since the net pull of gravity everywhere inside a hollow sphere is zero. Harry
