Comment on Does Mach speed change depending on the altitude?

  Technically it would reach an altitude where it would become null due to dividing by zero. You would eventually hit the vacuum of space where there is no speed of sound and any speed is faster than it.

      That’s where speed is relative. But if you had to use a Mach number, it’s be at sea level or standard temp/pressure
