Be nice, Lost....
I'll have to withhold your lollipop today...
PS
When a tree falls in the woods,... it makes a vibration in the air...
The sound,... is a sensory interpretation....
So,... it makes no sound.
Quantum theory would say the tree isn't even there, until it is sensed... it's just an area of organized vibrations waiting to be interpreted...
Spooky...
