I wonder... what's the speed of sound in unobtainium?
It can't be greater than or equal to the speed of light--that's the ultimate relativistic limit, even for unobtainium, superbium, idealmaterialium, etc.

Sound doesn't propagate through the unobtainium.

Well, we don't have an actual test lab here, so all we can tell you is what the theory says. :wink:
Particles have been accelerated to near the speed of light, so it is known how much energy and force is needed. The results agree with the theory to an impressive degree.

Bertozzi even filmed a simple test of this, and somebody put it on YouTube:
