Caught my eye, too. A big “huh”?

Wiki: “The vacuum of intergalactic space is not devoid of matter, as it contains a few hydrogen atoms per cubic meter. By comparison, the air we breathe contains about 10^25 molecules per cubic meter.”

Not much of a medium to conduct sound, is it?

Nope, which makes me wonder why it is so much faster in space than in air or water since the denser water conducts it almost 5 times as fast as the thinner air. Must be it uses wormholes......

A few hydrogen atoms per cubic meter?? Hard to imagine any sort of "ripple" or "wave" effect going on in that sparseness.
