True, but I forgot to mention that when you consider that at the center of a body, be it planet or star, you don't actually experience any gravitational pull as there's an equal amount of mass all around you - up, down, left, right, in front, and behind - so you would essentially be weightless when you're in the same location as the center of mass.
Maybe in fluidic space, every location is essentially the center of mass, like how in normal space, every location is the center of the Universe. Of course pressuse density is another matter entirely, but it seemed to be negligible other than sending a compression wave.
The fluid in fluidic space would exert upon itself an unbearable pressure and voyager would have been crushed like a plastic cup in the hand of Hulk, a day when was really angry.
