With whom are we sharing the rest of eternity?

If I've gotten the right impression, much of our currently visible universe will eventually be expanded away from us, never to be seen again. Do we already know how much and what parts of our present neighborhood we'll be left huddling with?

Are satellites built from old metals to avoid post-A-bomb radiation levels?

Are satellites (or satellite parts) ever made from metal salvaged from pre-1945 shipwrecks? Possibly to ensure that those metals were refined before atmospheric A-bomb explosions increased the background radiation levels? [more inside]

Factoring 'Time' into Astronomic Observations

AskMeFi Physics folk: How do astronomers account for the temporal distinctiveness of their galactic subjects in their calculations? I understand that observations of the red shift of quasars delinates a speed increase in the expansion of the universe - yet my brain explodes when I try to understand how the enormous expanse of time is factored into these models.

Is faster-than-light travel possible?

I've been somewhat obsessed with faster-than-light travel lately. Are there any scientists seriously studying thing such as the Alcubierre drive or other plausible, albeit exotic, ways to get from point a to point b without taking a million years? Is this something that just lacks the funding for any respected physicists to get involved? Surely there must be a department within NASA working on something a little more fun than sending a chemical rocket to a close planet. [more inside]
