If a tree falls in the middle of a forest and nobody hears it, has it even made a sound?
unless this box has a light bulb or some other source of light inside then...............no
Yes it does, the molecules still move and create waves.
Nothing can travel faster than the speed of light, not even Royston Drenthe. In fact, not even light most of the time.
Hypothetically though, the answer is 81.
Yes it does, the molecules still move and create waves.
But unless that wave then vibrates inside an ear, with said ear transferring the info to a brain, was their sound ? For after all, what is sound ?
Edit : I see Pyscho Pat has already dealt with this. Soz.
no Groucho !!!
the sound waves can move about as much as they like but until there is somebody to pick up these waves audibly then there is no sound !!
