Teleporting in a straight line from one edge to the other had no problems, but moving any significant distance spinward or antispinward resulted in too high a difference in relative velocity that could not be compensated for. | |

| Jan 29 at 11:23 | comment | added | Jason Patterson | I recall a similar short story, (Asimov, one of his one or two pagers???), whose title I can't recall or figure out about a pair of scientists who test their teleportation vehicle only to find themselves in a completely empty void. They quickly figure out that they accounted for the motions of the planet, star, and galaxy through space, but they didn't account for the motion of our universe through a greater medium still and have stepped out of it entirely. Now they're a perturbation in an otherwise high density universe and ... big bang. Sorry for the lack of detail re: origin. I tried. | |
