How large would a world have to be for a sailing ship to never make it past the horizon?
This might count as cheating, but...
Don't make the world a planet. The reason we see a horizon is because of the curvature of Earth. If you have negative curvature, there is no horizon.

In a world without obstacles, would life evolve wheels?
Technically, life on Earth has evolved wheels a few times already. The best known example is ATP-synthase, which is a full blown engine and very successful - as far as I know, all modern Earthly life …

Is there a reason to believe that programming languages are going to converge?
What programming (or other!) languages can't do is just as important as what they can do.

Could life form in outer space?
Okay, so what do you need to have interesting life?
It should be capable of movement. This is handy, because it makes it active. Not entirely necessary, depending on the kind of story you're making ( …

Why would they? They're just here to punch the clock. Invading planets nine to five, then check out and relax. And you know what? If you get killed, you get a vacation. Of course, it must not be obvio …

Is there a precedent for inventing a new technology many years before anyone else?

Will unattended nuclear power plants actually cause damage to their surroundings?
Short-term, it's probably safer if they don't shutdown. When the generator no longer produces electric power, the cooling of the residual nuclear reactions depends on power coming from the grid - if t …
