DARPA, the Pentagon department tasked with nurturing Mad Science in all its most speculative forms, had decided to throw a brainstorming conference on the 100 Year Starship—a mind-meld to try and figure out what research they’d have to conduct in order to have a hope of beginning to build a starship some time in the twenty-second century. And for no reason I clearly understood, they decided to fly in a bunch of SF authors from all over the world. I’m not sure why the Pentagon might want a starship, but I was glad someone was paying for me to go to Orlando and kibitz on their conference, and I was happy to bloviate about such things from a hard SF point of view. The 100YSS conference exceeded all my expectations—and everyone else’s. But the sheer amount of information on tap made the experience feel a bit like trying to drink from a fire hose. It turns out there’s a lot we don’t know about how to build a starship, but also a lot that we do know, and this was the mother of all networking opportunities for folks with an interest in the field.
