What if I said our explanation of our world makes sense. But it only makes sense in our minds, where we can break the world up into discrete pieces that interact with each other. Experimental physics can agree with theoretical physics in some situations, such as relatively simple, coherent systems under times that are much less than infinite and initial conditions that have finite, distinct variations.

However, the universe is not this easy. Here, we are dealing with systems which have an infinite amount of initial conditions and very large times. One small difference in initial conditions permanently alters the slope of our future line; one small difference in our starting conditions changes the outcome completely. Physics requires us to be able to measure initial conditions accurately in order to obtain an accurate result. Physics as we know it is impossible to use in a chaotic system-impossible to use in the universe we live in.
