at which point you're only seeing your brains interpretation of electrical signals from the optic nerve anyway.. so does light even really exist? i <3 quantum mechanics
Mind = blown.
It's like saying "If a tree falls in a forest but no one is around to hear it, does it make a noise?"
My answer is that it creates the sound waves, but it won't become a noise until it hits the eardrum and is converted into a signal recognisable by the brain.
