"tree falls in the forest type question"

That is a bogus question.. not a profound question.

A tree falling in a forest makes no sound ever. A tree falling in a forest always causes the air around it to vibrate.

The Earth is silent. Sound is our brain's interpretation of vibrating air. Sound is a function of humans and not a function of trees.

I don't think you understand the question. You POSTULATE the falling tree vibrates the air. You are PROBABLY right. But you have no way of KNOWING, since no observation takes place.

It keeps sophomores up at night, like the universal existence of the term that sounds like "jinantonix" keeps sophomore lingists up late at night.
