If nothing exists and a universe is created via a big bang... does it make a sound? Can we realistically call it a big bang if it doesn't make a sound? Couldn't we call it the big light show? But then again... if nothing exists and a universe is created via a big light show... does it matter? Can it be perceived? Is this just a proverbial pandrödinger's box? You can't implement the bigbang() function if you don't exist.
