If a tree falls down in the forest and no-one is around to hear it, does it make a sound? (experience, verse)

If it cannot be seen, it isn't there.

But being matter there is nothing else that can take up that particular space in the universe whether it can be perceived by initial human senses or not, therefor it does exist as it can still interact on some level.

The air will record the shock of the fall in waves. The record will be lost, however, as no one was there to receive it.

Wow, what a silly comment...


Energy can not be created or destroyed. A tree has gravitational potential energy. When the tree falls, that energy is lost, and it MUST be converted into something. It is mostly converted into thermal (heat) energy, and partially converted into sound energy.
If no one is there to listen, that sound energy has still been created.
