SciFiFilter FTL-ish Plausibility Check

In a discussion elsewhere on the internets a twist on a common science fictional transportation technology was proposed. A spaceship leaps from one point in space to another, but while it is instantaneous for the passengers, the transit actually takes some small amount of time longer than light would take to cover the distance (let's say the Planck time). Would the time delay prevent the violation of causality? It appears that everyone is staying in their light cones, what am I missing? [more inside]

How would a spaceship be protected from solar wind and deterioration?

Once we develop the technology of manned, long-term space travel (such as star trek, for example), how would our spaceships hulls and housing be protected from things such as solar wind, other "energy debris", and deterioration? [more inside]

Cosmos has me very intrigued. Assume I know less than a 5th grader. I am looking for: book recommendations for basic astronomy concepts; blogs; podcasts for beginners; good audio books; and documentaries. If you wanted to teach an adult about astronomy where would you start?

Why don't we have HD video of Earth rotating in space?

Why don't we have HD video of Earth rotating in space? You know, relatively close-up, as if the Enterprise had just dropped out of warp and the planet was being majestically introduced to the cinema audience. An extended, multiple pass/rotation exposure, so that it could be watched by appreciative viewers wanting to get a bit of perspective/peace. I imagine I would sit and gaze at this for extended periods. What are the technical limitations which have prevented this?

Rockets and Tubes: Why not?

Why do we not launch rockets out of tubes? If the most expensive bits of launching a rocket are the first few feet off the ground, why don't we put the rockets into a tube to make launching more efficient? [more inside]

Can you collect meteorite dust in your backyard? How?

I've been told recently that collecting micrometeorites is as easy, basically, as placing a clean surface outside and picking through the debris you collect because thousands of tons of space dust and debris fall to Earth every day. That can't be all there is to it, can it? How do you know whether you're looking at Earth dust or space dust? [more inside]

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?

What the Hell, is that a UFO?

I am interested in reading books on UFOs both pro and con. Not really much else to the question. Not so much on individual abduction bios but more on theories on why (or why not), conspiracies, debunkings, and so forth.

Recommended Space Operas

With the completion of the Star Wars sextology [sic], I was looking for recommendations of other science fiction/fantasy space operas. I just bought the Doc Smith's Lensman "prequel", Triplanetary, and his first Skylark book. Any other suggestions or comments on these (i.e. should I start with Galactic Patrol in the Lensman series? Read Skylark before Lensman)? Suggestions from across all media is welcome (Babylon 5, etc.).
