...envisions launching a four-person spacecraft to Mars--but launching it with its tanks empty of fuel and its cabin empty of crew. Landing on the surface, the craft would begin pumping Martian atmosphere--which is 95% carbon dioxide--into a reaction chamber, where it would be exposed to hydrogen and broken down into methane, water and oxygen. Methane and oxygen make a first-rate rocket fuel; water and oxygen are necessary human fuels. All these consumables could be pumped into tanks inside the ship and stored there...
...universe is destined to collapse, ultimately dissolving into a fireball--a Big Crunch that amounts to the Big Bang run in reverse. If it's not, and expansion wins out, then the universe will eventually grow unpleasantly dark and cold. Stars produce energy by fusing light atomic nuclei, mainly hydrogen and helium, into heavier ones. When the hydrogen and helium run low, old stars will sputter out without any new ones to take their place, and the universe will gradually fade to black. Such were the gloomy alternatives that Robert Frost wrote about after being briefed on the theory...

...enlarge and expand. We have recently found out that the entire universe is expanding more than we had initially believed. We build, invent and discover at a pace that is dizzying for us, perhaps turtle footed for you. This year the automobile industry produced a vehicle powered by liquid hydrogen; Detroit plans to have fuel-cell cars on the roads in 2004. (I assume yours run on carrots.) The computer industry comes up with a "killer app" every 18 months. With silicon chips reaching their limit, the industry announces "molecular computing"--shrinking computer circuits to the size of molecules. Soon...
