cellio | Judaism and SF

Wandering Stars is the classic compilation of SF around Jewish themes, including halachic issues that just don't arise in day-to-day life like whether space aliens can convert (and, IIRC, managing the calendar on other planets). Some of my readers might be interested in the following speculative questions that have been asked on Judaism.StackExchange:

Does the torah discuss (space) aliens?

Time travel and Judaism

If a pig was genetically modified to chew its cud would it be kosher?

(I just posted these on an old entry in response to a comment (was cleaning out spam and noticed it), but I then thought they might be of more general interest.)

Edit:

The following were contributed by Isaac Moses in a comment:

Can a robot be your rabbi? (As if we don't have enough trouble with people thinking that a website can be a rabbi.)

Does Robot = Golem?

Can a robot be your official agent? Looks like your anthology can have a whole section on robots.

If you can drive a car using only your brain, can you do that on Shabbat?

And based on another comment, I just asked: When does somebody living in space observe shabbat?
