A handful of celebrities — and a variety of other people with far too much money on their hands — have paid a reported $200,000 deposit each for a seat on an intergalactic flight on Richard Branson’s first-ever commercial space flight, Virgin Galactic. Paris Hilton, William Shatner, Sigourney Weaver and Tom Hanks are four of the 157 people who have signed up. However, Paris Hilton may be having second thoughts, according to Bang! Showbiz. She says, “I’m very scared to do it. What if I don’t come back? With the whole light years thing, what if I come back 10,000 years later, and everyone I know is dead? I’ll be like, ‘Great. Now I have to start all over.'” The first flight is planned for 2010.
