So, I've got an idea for galactic travel involving some fancy particle physics and the Higgs-field, but I've just discovered I don't know how teleporting really works. Or any of that kind of stuff,...

I want to build a habitable desert gas-giant moon and I´m not sure how little water I can give it and still get plate-tectonics instead of an Io-like lid-tectonic setup. I want plate tectonics bec...

I'm trying to build a super Earth that's capable of sustaining human life for space exploration in a way that's close to reality. So far I'm lacking some understanding of planetary science and huma...
Suppose that for some reason gravity magically changes, but only for people. While this goes on, instead of gravity pulling people down, it pushes them East. To be clear, it's just people. Not anim...
There have been many (many) questions around here about the how, why & even when will man kind become a multi planet society... this is not one of them. This question in fact goes the other wa...
