"One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely," said Burko in a telephone interview from his office in Salt Lake City. "It depends on the topology of the universe, which we do not know very well ? Im not arguing its a practical thing to do, but maybe in 1,000 years from now, maybe it would be simpler." In Burkos scheme, black holes may be doorways to wormholes, theoretical constructs equivalent to tunnels, or shortcuts, between distant points of the universe, different points in time, or even parallel universes. Burkos ideas arent new. Wormholes were popularized by Caltech physicist Kip Thorne in the 1980s, and were the interstellar vehicle of choice in Carl Sagans influential novel Contact.
