Re: Hear the sound of the Big Bang



Well, you are dealing with a rough description that is intended for the
general public, never a good source for obtaining accurate info. However,
"inflation" is the word you are looking for. In this case, it is not matter
moving faster than the speed of light (which as you point out -- is not
possible). Instead, we have the expansion of space itself, which can expand
at a rate which gives results that look like matter moved faster than light.
