The campus is sponsoring a convention for time travelers
Why not, say some students at the Massachusetts Institute of Technology, who have organized what they call the first convention for time travelers.
Actually, they contend that theirs is the only time traveler convention the world needs, because people from the future can travel to it anytime they want.
"I would hope they would come with the idea of showing us that time travel is possible," said Amal Dorai, 22, the graduate student who thought up the convention, which is to be this Saturday on the M.I.T. campus. "Maybe they could leave something with us. It is possible they might look slightly different, the shape of the head, the body proportions."
The event is potluck and alcohol-free - present-day humans are bringing things like brownies. But Mr. Dorai's Web site asks that future-folk bring something to prove they are really ahead of our time: "Things like a cure for AIDS or cancer, a solution for global poverty or a cold fusion reactor would be particularly convincing as well as greatly appreciated."
This doesn't come without its practical benefits:
He would also welcome people from only a few days in the future, far enough to, say, give him a few stock market tips.
I'm not from the future, but I've got a tip: don't buy General Motors.
Time travel will never be invented if politicians and prominent figures can help it. The risk is too great that the technology will be used to get live video of their pasts. Just imagine what those SwiftVet ads could have been like.
