Alex,

***Free falling rock obeys mathematical laws...explain, WHY SO?***

There is a long chain of mathematical and perhaps physical reasons why it is so. We can't say it is purely mathematical reasons because free falling rocks involve the constant G which may not be a mathematically derived constant.

The question isn't whether there is an immediate reason (i.e., equation) for a physical occurrence. The question is what do all of these laws ultimately depend upon? That is, what sustains the laws of physics?

Why don't the current laws stop being the way they are, and maybe start being the laws of an alternative universe? What keeps the laws and constants from changing (or if the constants are changing what keeps them from changing faster or slower)?

In my view God sustains the laws of physics. What sustains the laws of physics in your view?

Warm regards, Harv
