Not going to attempt to make picture of this, but I figured out FTL travel.

You're in a plane that is travelling at the speed of light.

You stand in the back of it and run forward.

You just ran faster than the speed of light.

Except that it's still fucking impossible for a plane to travel at the speed of light. You might as well just tell someone that to travel faster than the speed of light, all you have to do is run faster than the speed of light. It's impossible either way.

Well the logical fallacy is actually that time would have slowed down inside the plane, so you wouldn't really be running at the speed of light..

What is the relationship between time and speed? Does it run at close to normal until you reach c and then increase exponentially, or is it more linear?

roomate is drying his shoes next to the open window. Now it's cold outside. It's been sitting there all day and it's fucking freezing in the room. He thinks it can dry more with cool air.

Give me a complicated scientific explanation to prove him wrong.

It's funny, but except the reachign the speed of light part, it's actually quite complex to explain why the time dilatation effect doesn't work both ways.

You really think a little tree like that would produce enough air for a human? You'd be out of air in a matter of seconds. You would need a BUNCH of full-size trees, at least, and that's a bit more difficult to carry around with you.

Twin that comes back to earth has changed reference frames. Hence the asymetry.

You know, though, some of these ideas aren't trolls. They actually do things some of these ways, such as the double jump OP posted. You'd need fantastically heavy shoes, but you could.
