First, let us eliminate the scientific definition of “exist” so we can put that to rest. For something to exist scientifically, it must have form and location. Time has neither, nor do gravity, inertia, or centrifugal force. Unlike those Newtonian forces that also do not “exist” to the scientific standard, time is not universal. In other words, even though gravity, inertia, and centrifugal forces do not exist, they are universal laws that apply uniformly to physical objects in the universe. Time does not.
