</div>Well, I think we had better get some clarification on this before we send the first Israeli spaceship up. :-) Can an artificial gravity (caused, say, by a rotating spacecraft) make "down" and "up?" Alternatively, AIUI, a spacecraft that is orbiting a planet is still under the influence of that planet's gravitational pull, even if weightlessness reigns inside. Maybe "Down" in that case would be towards the planet it is orbiting.<br>
</blockquote><div><br>IMHO "down" and "up" in this context should be correlated to the relative position of one's head and body when entering the room, not gravitational pull as such. <br></div></div>
