Trees are pretty heavy, which means that they have a lot of gravitational potential energy. When they fall that energy has to be transferred into some other form. Some of it will be transferred into noise (movement of air molecules), both it cracking and then it landing on stuff!
It doesn’t matter whether there is anyone there to hear it or not!
A tree falls, somebody’s there, they here it, then Yes It made a noise !!
A tree falls, nobodies there, nobodies heard it, did it make a noise ???
If there is no evidence… we don’t know!!!
Common sense tells us ” yeah of course it must have made a noise….dosn’t it ??”
but… really.. we just don’t know.
NOW! this is where it gets a little crazy….because there are Experiments you can do where the answer you get CHANGES depending on whether your looking/ listening or not looking/listening when you do them
and these differences in the outcomes of these experiments.. they aren’t small…, they are HUGE difference!
These experiment have baffles scientist for years !
And the only answers they have come up with are
1) The universe is really weird …(don’t ask how it works!)
2) There are multiple universe and which one you’re in depends on where you looked or didn’t look.
So…Does a tree that falls in the forest make a noise when no bodies there?,
Well…..Depends what universe your in ! 😛
