| Words Faster than the Speed of Sound... [+ favourites]
I was thinking last night and came across an interesting fact... People who traveled on the Concorde could easily hear each other when they talked, even though the Concorde travels faster than the speed of sound (around Mach 2 at times)... I then hypothesised about it being possible to further speed up sound, perhaps faster than the speed of light (and maybe much faster still)... (I then thought it would be impossible to slow the speed of sound down or increase the speed of light with similar methods, and then starting fantasising about talking to people on the other side of the Universe in near-real time...)
"There is no negative one..."
