At least somebody's thinking ahead -- way ahead:
NEW YORK (AP) — PayPal wants to explore space — or at least begin to figure out how payments and commerce will work beyond Earth's realm once space travel and tourism take off.
PayPal, which is eBay Inc.'s payments business, says it is launching an initiative called PayPal Galactic with the help of the nonprofit SETI Institute in Mountain View, Calif., and the Space Tourism Society, an industry group focused on space travel. Its goal, PayPal says, is to work out how commerce will work in space.
Of course the real question is how we handle commerce with the aliens when they get here. I mean, I would be reluctant to accept a credit card from someone who might zoom light years away any minute. Bet I know the first thing out of their mouths after they land: "Take me to your lender."
