Dr. Krauss. I have friends who own an SUV that gets absurdly low mileage. I would like to know where I can get a gallon of inflationary spacetime, so that I can add a tiny bit to their gas tank, ...like drygas, with each fill-up. That way, since it expands carrying the matter along with it, indefinitely, and at superluminal velocity,..they can get about a million miles a gallon. (They drive a lot.).Thanks. Ciao. Pete.

P.S. When I asked this question while a visiting scientist at MIT, they laughed so hard they couldn't talk and tears came to their eyes in the particle physics labs. If you climb out on a limb,...somebody will saw it off. Pete.
