How does animal size affect individuals' agility and speed? This question is a bit of an outgrowth of Can you simply scale up animals?, but it does approach it from a different angle. "All else equal" (which it of course never is, but we're good at pretending here, so let's pretend), heavier animals tend to be less agile than their smaller counterparts. This... (more) |

A: Asteroid impact. How big does it have to be to globally affect plate tectonics? I'm going to talk about Earth below, but since you say "an Earth-like planet", consider that just an space-saving measure. Take an Earth-like planet, about the same size, composition and gravity. ... Huge (say 500 kilometer diameter) asteroid strikes. Well, as it's said in the movie... (more) |

How would societal development be impacted if humans were not an apex predator? We are used to a world where humans are basically an apex predator; we don't really need to worry much about becoming some other animal's next meal. If that wasn't the case, and humans had to be wary of the possibility of a predator either lurking nearby or openly hunting them, how would that affect... (more) |

A: What Factors Could Cause a World to See "Northern" Lights Much Closer to the Equator? Actually, and as also pointed out, auroras are sometimes seen in temperate latitudes on Earth, so are not restricted to high latitudes only (although they tend to be more common there). Taking Wikipedia at face value, there are a few things that can impact the frequency of occurrence of aurora act... (more) |
