...again, Einstein may have provided the answer. His 1915 theory of general relativity showed that space and time are curved, and that the curvature can be large in the neighborhood of very massive objects. If an object is dense enough, the curvature can become nearly infinite, perhaps opening a tunnel that connects distant regions of space-time as though they were next door. Physicists call this tunnel a wormhole, in an analogy to the shortcut a worm eats from one side of a curved apple to the other...
Using this idea, Thorne and his colleagues proposed constructing a wormhole tunnel 600 million miles in circumference, with Casimir plates separated by only 400 proton diameters at the midpoint. Time travelers would have to somehow open doors in these plates to pass through the wormhole. The mass required for construction? Two hundred million times the mass of the sun. These are projects only a supercivilization could attempt--not something for 21st century engineers...
...current scheme--substantially different from a 1998 version on another site--would replace Coolidge Hall and the University Information Services building with two buildings connected by a tunnel under Cambridge Street. The structures would allow Harvard to consolidate the government department and all of the centers for international study, leaving the Littauer Center entirely to the economics department...
...factories but warn that production is cropping up in central Europe and Spain. For good reason: Americans are in love with ecstasy. "New York used to be a meat-and-potatoes drug town--heroin, coke and pot," says John Silbering, a former narcotics prosecutor who works for the Tunnel, a big New York City nightclub. "Today we no longer find coke or heroin among the young. It's always ecstasy...
...have a competitive relationship," Spyder says. "There's a picture of her and a guy on the tallest building on campus, overlooking Cornell during a sunrise. She had to go into the steam tunnel, through a ventilation shaft and a nuclear accelerator, and then up an elevator shaft to get to it." Since then, Spyder has wanted to beat his sister at her own game...
