I don't undersatnd what you are saying... you simply have a perpective of the world where you see math and laws of physics as somewhere out there...on what planet, Pluto? Mars...under a rock somewhere? Where is it that these math rules and laws of physics exist at? maybe on an asteroid, a comet...inside a star? It has to be somewhere besides...in you mind. But where??? where is it at? Yous are no different than people who believe in flying saucers from outer space or, ghosts. There are just inventions of the mind... And I cannot believe people 'still' hang to a guy born 347 BC named Plato. Plato invented the inventions of the mind.
