it's weird to think, if you try to measure the volume of a container by filling it with water and measuring the volume of that water, the mere presence of the water will distort space and result in a slightly smaller volume than if it contained only air, or vacuum
this thought brought to you by Felthry's pondering how one would measure the total volume of a universe with non-flat curvature
@Felthry This made me jump slightly
@VoxSomniator why so?
@Felthry A powerful expression of "WOAH COOL"
@VoxSomniator especially anything involving quantum field theory or general relativity or double especially both
