Question	—	Seasons without an axial tilt? Let's assume we have an otherwise Earth-like planet orbiting a star just like our own. Our planet has an axial tilt of 0 degrees, meaning its axis is perpendicular to its orbital plane. Could this planet have seasons based solely on where it is in its orbit? My thought was to increase the eccentrici... (more)	—	about 7 years ago
Question	—	Making a Counter-Earth In this question, it's pointed out that the L3 Lagrange point, where a "true" Counter-Earth would lie, is in fact unstable, and over time any object there would drift into a different orbit. Obviously this means that if we're going to put a habitable planet there, we need to give it some means of st... (more)	—	over 9 years ago
Question	—	What if we never stopped growing? As I'm sure you're all aware, human beings at some point in their lives -- generally post-puberty or so -- stop growing. As a result, there's some easily-predictable measures, such as the average height of a human, and some pretty consistent standards in our society, such as the height of a typical d...

Question	—	Can we breathe the moon's crust? According to this answer to what the moon is made of, the moon's crust is, among other things, 43% oxygen. Assuming we were to go back to the moon within the next couple of years with the goal of establishing a long-term presence (read: base/colony), would we be able to process the crust and extract...

Answer	—	A: What are the power options for intelligent humanoid robots? The power requirements are going to be highly variable. Just think about today's electronics -- you could put a set of AA batteries into your TV remote and have it work for years, but an identical set of batteries from the exact same package in your stereo remote dies in 6 months. More to the point ... (more)	—	about 10 years ago
Question	—	Automobiles after the apocalypse So last year I started writing a post-apocalyptic story, and then realized I had no idea what the world was really like, and quite a few things just didn't seem to make sense. One of the biggest that jumped out at me was the abundance of running automobiles tooling around in my story. Which got me t... (more)	—	about 10 years ago
