There's a phenomenon in quantum mechanics known as quantum superposition.<br /><br />You may have heard that light has properties and behaviors that match those of both waves and particles. If you fire a laser beam at a screen, filtered through a barrier with two slits cut in it, the light on the screen forms a neat-looking interference pattern with distinct light and dark regions. The evidence from this famous double-slit experiment suggests that the photons that make up the laser beam appear to occupy all possible positions they could occupy, simultaneously. Well, at least until you try to observe a photon in isolation rather than the interference pattern as a whole. To those who don't accept the Many-Worlds interpretation of quantum mechanics, the act of observing a quantum particle's position is known as "collapsing the wave function," and it forces the observed particle to pick a phase state to occupy. In other words, the very act of opening Schr&#246;dinger's box determines the fate of his cat.<br /><br />And then there's Kassie, who says, "Screw that. I'll take up as many spaces as I want! Science can't tell me what to do!" And to be fair, although the number of "phase states" she can occupy is still capped at three, she's got a point. They can even touch each other, much to the delight of herself and would-be voyeurs.<br /><br />Enjoy the voidling! :3
