Only 3. The universe is very fair. What falls through a wormhole eventually sqiggles through the spatial warpfields and ends up somewhere else, somewhen else, or as something else entirely. Light entering a raindrop gets polarized, reflected, and refracted before bouncing clear. Same thing with matter (energy equals matter, after all) in a warpfield. The question is: were the 2 extra copies yours, or a pair of socks that I'm going to lose next year? Carolly
