[QUOTE="spiney, post: 272142, member: 192438"] The "life chain" is very tied into day/night, and I'm not sure anything would survive at all (there would be no plants on half the earth!), but assuming the human race still exists: 1) Air travel would be the same (speed is relative to ground!). 2) Gravity will stay the same (this depends on earth's mass!), and there will be no noticable change in weight (just as there isn't now, at either pole!). 4) It's true that we'd lose the "help" of the earth's rotation for equator launching (why rockets are usually launched near the equator), but would still be possible. However, by that time, presumably we'll be using "space elevators". An interesting sci fi novel about a "still earth" is Aldis' "Hothouse" (one of the few readable novels he's written, despite being a superb sci fi theorist and historian). I'm not sure the earth will stop before the sun goes nova (like on Dr Who). [/QUOTE]
