The only man who ever came close to understanding that a new universe had been created was a biologist. A junior biologist by the name of Hank Tapper, attached almost as an afterthought to one of the geological teams sent to study the disaster. The team devoted several months to a study of the terrain which had replaced what had once been part of West Virginia. They came to no conclusions other than the obvious fact that the terrain was not indigenous to the area, but that-this eliminated the once-avid interest of the SETI crowd-it was clearly terrestrial.
The size of the foreign terrain was mapped, quite precisely. It formed a perfectly circular hemisphere about six miles in diameter, approximately half that deep at its center. Once the team left, Tapper remained behind for a few more months. Eventually, he identified the fauna and flora as being almost identical to those of parts of Central Europe. He became excited. That matched the archaeological report, which-very, very diffidently-suggested that the ruined farmhouses on the new terrain had a vaguely late-medieval/early modern Germanic feel to them. So did the seven human corpses found in one of the farmhouses. Two men, two women, and three children. The remains were badly charred by the fire, but marks on the bones indicated that at least two of the people had been murdered by some kind of large cutting implements.
The dental evidence suggested that the dead people were not modern. Or, at least, had somehow never been given any kind of dental treatment. But medical examination determined that the murders were very recent. And the farmhouses were still smoldering when they were found.
Tapper teetered on the edge of the truth. Then, after several more months of work failed to turn up any matching piece of disturbed terrain anywhere in central Europe, he abandoned the study altogether. He had suspicions, but-
The only possible explanation was a transposition in time as well as space. Tapper was a junior biologist. His budding career would be ruined if he advanced his suspicions without evidence. And there could be no evidence, if he was right. Whatever remained of the area of West Virginia which had vanished was lost somewhere back in time.
