Disagreed that's what
@Cypress thinks. He's simply recognizing that the Universe is logical and, therefore, predictable in its actions. The main variable is life, which alters the Universe in, sometimes, unpredictable ways.
An example is the flow of water off mountains and down to the sea due to gravity, temperature and other predictable events. Water and gravity carved the Grand Canyon over time. Life, OTOH, can alter that predictable results such as beavers damming streams which can alter their course or slow their flow. Life downstream of the dams may flourish and further impede water flow.
Predicting physics over hundred thousand or a million years is easy but predicting the course of life over the same time period is not.
