  • My favourite foil cap trope reference is Brandon Sanderson’s Mistborn series. It has several characters with supernatural abilities that can affect other people’s emotions, and aluminum happens to block all kinds of magic powers in Sanderson’s larger book universe. So a lot of rich and important people wear hats that are lined with aluminum foil on the inside to protect them from emotional influence.








  • It’s exactly what the other commenter said, to transfer heat efficiently you need something else to transfer it to. In a vacuum, you only lose energy by radiation. Therefore on a spaceship you’re actually in greater danger of overheating than freezing to death.

    Another counterintuitive thing that stems from this is that space vacuum isn’t even, strictly speaking, cold. The few and far between particles of space dust and gas can have very high energy flying by, at least until they hit something. It’s only cold when you average out over all the empty space.
