http://www.ekkehard-friebe.de/wallace.htm Dying Bryan Wallace: "I expect that the scientists of the future will consider the dominant abstract physics theories of our time in much the same light as we now consider the Medieval theories of how many angels can dance on the head of a pin or that the Earth stands still and the Universe moves around it." http://www.princeton.edu/main/news/archive/A97/94/63I40/index.xml "We have had time travelers already," Gott said in an interview at his Peyton Hall office. "The greatest time traveler so far is (cosmonaut) Sergei Avdeyev, who, by virtue of being on space flights for 748 days, is one-fiftieth of a second younger than if he had stayed home. So that man has traveled one-fiftieth of a second into the future." The key to time travel of any sort is the bendable nature of time, as described by Einstein's theories of relativity. "Einstein showed that moving clocks tick slowly," Gott explained....."Regarding time travel into the past, Gott said it may be possible, but much more difficult. One idea, developed by Kip Thorne and colleagues at the California Institute of Technology, involves "wormholes," which are shortcuts from one part of the universe to another. The other, which Gott proposed in 1991, involves two "cosmic strings," which are filaments of very dense matter left over from the early universe. When two cosmic strings pass each other at a great enough speed, someone traveling around the strings would be transported back in time." Pentcho Valev pvalev@yahoo.com
