that is time for a scale model runs faster than full scale, by the square root of the scale factor.
Did anyone tell Einstien? Would this mean that a scale rocket ship can go faster than the speed of light?
Not a chance. Because Special Relativity says that the scaled down object aproaching the speed of light will increase in mass and length (it's complicated) as it gets closer to the speed of light. So, entually returning to it's original scale.

It's an interesting thing to imagine though.

You can read about NASA's take on scaling here:

They are no longer so sure about that. In fact they think they have observed particles being in two places at once, possibly being in another deminsion and other things that may violate special and general relativity rules.
