Math is illogical, Captain.
Law of explosion says logical contradiction leads to deductive explosion.
x=-x is the arithmetic description of a self-contradicting (ie self-negating) arithmetic logic element.
Arithmetic axioms lead to the logical contradiction x=-x at x=0 because 0=-0 which can only be described as an oxymoronic valueless value.
Arithmetic is a numerical explosion of logic, all statements of truth made by arithmetic are trivial truths among infinite truths because its original number is a self negating logical contradiction.
The Standard Model of Physics is an emergent property of arithmetic by way of geometry, any models produced by physics, such as strings, rings, lies, groups, manifold, quantum foam or ultimately big bang, rely on arithmetic that is irrational at its core 0=-0 and not an accurate reflection of nature, by definition of logical contradiction and through the consequences described by the law of explosion.
Total incoherence is at the most extreme poles where zero and infinity might as well be equivocated in their trivial projections.
0 = 0 x 0 x ...
infinity = infinity x infinity x ...
Arithmetic/Physics is either irrational and does not make measurable predictions about nature or nature is irrational and can evade quantification predictions infinitely.
This is why the best physics explanation is called a big bang, it is not a big natural bang, but a big numerical bang of arithmetic, geometric, physics, ..., inf, etc explosion based on a logical contradiction.
The application of math to nature is immeasurable with math, math is based on a logical contradiction and trivial in nature due to a deductive explosion.
12th century Logic debunks 21st century math.
Arithmetic prediction system is an incoherent, trivial, explosion of paradoxical logic.
