What steps should I take to switch to the aerospace industry from the academic world? [more inside]
Work in my office has ground to a halt over this question about the physics of fish in space. [more inside]
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 (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]
How would you get through a black hole? [more inside]
Was the entire universe created by the Big Bang, or is the space/time generated by the Big Bang part of a larger universe?

Does the curvature of space mean that the dimensions of height, breath and width are not independent of each other? [more inside]
Let's say you're thrust headlong into a dogfight engagement in space. Era and galaxy of your choosing. What would the real-world physics look like? [more inside]
Would a bag collapse if I sucked the air out of it in outer space? [more inside]
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.

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]
What would happen if someone were to build a tunnel or tube into space? (Description inside...) [more inside]
