Stephen Hawking Rises from His Chair


Stephen Hawking is planning a warm-up for the flight he has booked on Virgin Galactic in 2008 or thereabouts. He'll be sampling a little bit of zero gravity next month:

Hawking, surrounded by a medical entourage, is to take a zero-gravity ride out of Cape Canaveral on a so-called vomit comet, a padded aircraft that flies a roller-coaster trajectory to produce periods of weightlessness. He is getting his lift gratis, from Zero Gravity, a company that has been flying thrill seekers on a special Boeing 727-200 since 2004 at $3,500 a trip.

Peter H. Diamandis, chief executive of Zero G, said that "the idea of giving the world's expert on gravity the opportunity to experience zero gravity" was irresistible.
