IT’S NOT THE PEOPLE, IT’S THE EVENT, PART 1

The models of physics cannot depend upon the point-of-view of the observer.  In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events co-occur – is not absolute but depends on the observer’s reference frame. Invariance, covariance, and symmetry:  Invariant: Any physical quantity is invariant when its value remains unchanged under coordinate or symmetry transformations. Covariant: The term covariant is usually used when the biological systems’ equations are entire under coordinate transformations. An object that is invariant under some changes. In physics, a physical system’s symmetry is a physical or mathematical feature of the plan (observed or intrinsic) preserved or remains unchanged under some transformation. In physics, symmetry is usually used to refer to an object in translation, reflectionrotation, or scaling.
