  General relativity and quantum mechanism are two separate rules of modern
physics explaining how nature works. Both theories are accurate, but the direct
connection between two theories was not yet clarified. Recently, researchers
blur the line between classical and quantum physics by connecting chaos and
entanglement. Here, we showed the early reported extended HM theory that
included the general relativity can also be used to recover the classic chaos
equations and even the Schrodinger equation in quantum physics, suggesting the
extended theory of harmonic maps may act as a universal theory of physics.
