Data compression algorithms can be classified in two categories: those with data loss and those without data loss.

Einstein had posited that large gravitational forces could stretch light, much like the compression and stretching of sound waves we perceive with the change of pitch of a passing train.

Temperature is mean kinetic energy, not energy over volume; compression heats a gas by doing work on it; and a gas that expands without doing work does not cool.
