The best fictional way to travel through space fast without messing with time is teleportation.
The planet Mercury does not have an atmosphere in the same way that the Earth has an atmosphere; it has only a very thin layer of gases far above its surface. Because sound cannot travel in a vacuum, there would be no speed of sound on Mercury.
This is a low temperature. It travels in less than 340ms-1.

The rate at which sound travels through stone depends on the stone. Sound will travel faster through warm stone than cold stone.
it travels at 250-275mph
You'd have to say that the speed of sound waves in vacuum is zero, becausesound can't travel through vacuum at all. Not even an inch. Sound needs amaterial substance to travel through.
