Yesterday I considered how long it would take a human to freeze in space. However, I considered only what would happen if you were not absorbing any radiation from nearby sources. Today we consider what happens if you do have hot objects nearby. Namely, the sun. The sun provides a lot of energy, even as far away from it as we are. It keeps the earth at a comfortable ~20 C, good for us humans, and provides the energy for life on earth, also good for us humans. That's a lot of energy. So maybe the sun can keep you alive when you're adrift in space. Or at least keep you warm. I still think you'll asphyxiate.

Freezing in Space I - Blackest Night

In the last post I made, I discussed the fact that humans radiate energy. In that post I calculated that we actually radiate quite a lot of power. This immediately raises a few questions, the most obvious one being: How long would it take you to freeze in space? This question is multifaceted, and I'm going to split it between two parts. This first part, 'Blackest Night' is how quickly we'd freeze if we were completely lost in space, nothing anywhere near. The second part, 'Turn On The Sun!' will address what would happen in near earth orbit.
