When it dries, why do you think wood splits from the center to the
perimiter? I think I have finally worked it out, just wanted to know
what you all think first

I think the easiest way to understand it is this - think of a flat sawn
board. As a woodworker, you know the board will shrink most in width, a
little less in thickness, and almost not at all in length. It is the
difference in shrinkage between width and thickness that matter. Then think
of that board within a round log. Because the log is shrinking radially
greatly, but in diameter only slightly, the fibers are pulled apart radially
around the log.

Not a scientific explanation, but an easy one to grasp.
