Yes, sonic is meaningless as a benchmark in space. The speed of sound varies with air pressure (altitude) but it is always an important barrier in a gas atmosphere. However, in space it means nothing. A bullet fired into a gravitational well could just keep accelerating until it struck something or went into an orbit.
- echoangle 3y agoSpeed of sound is not affected by pressure, only by temperature. It’s still variably with altitude though because the temperature is dependent on altitude in the atmosphere.
- s1artibartfast 3y agoTIL!
- TeMPOraL 3y agoAt those speeds, the two are probably the same anyway.
