What is THE sound barrier?
I heard a man broke it... :)
Its the speed at which sound travels, if you break it, you a loud bang occurs, the barrier isnt a barrier, but just a point of speed, although if you mess up, you can bounce back due too the air pressure, causing you too lose control
It's a kind of wall that you can only get through by being extremely loud and fast.
The "explosion" sound that occurs when something reaches the speed of sound.
