Maths is based on axioms (those are the 'rules') you'd have to change them for Maths to change. A DIFFERENT Maths could be inexact but not the one we know and love, because it is consistent in itself. That's not to say that you couldn't get one apple and another apple and end up with three apples - or at least something like that could happen with wierd particles. But that's not maths. It's reality - or a possible version of a reality.Physics is NOT exact, in any case. There are two fundamental reasons - Heisenberg's Uncertainty Principle says that you can't know a body's speed and position accurately at the same time.Every measurement is perturbed by the background 'noise' in the measuring equipment, which it there because of thermal vibrations and what is happening at the atomic level in your measuring device.Then there is Chaos, which was discovered fairly recently and which tells us that, in certain systems with what is called non-linearity, even vanishingly small differences in starting conditions can produce wildly different results. The popular image of a butterfly beating its wings in South America causing - or not causing - a hurricane a thousand miles away, is an example of chaotic systems.Three reasons why Physics cannot be exact without any fantasy scenario being involved. The Victorians believed that Physics was more or less sewn up but then these three ideas came up.
What would happen if all of the sudden say tomorrow at 6:59 am math and physics ceased to be exact?
How about this for your idea?Physics becomes even more unexact and our brains can't understand the current axioms of math, onlyones that don't work, which would make math unexact.
