I do and time doesn't exist… its a made up concept to represent the position of objects/energy relative to one another… the construct of time is used to just relate these aspects a little easier… but in fact time cannot be observed or measured… its all relative to a definition … originally based around the cycles of the earth around the sun… moon around the earth and rotation of the earth… although now redefined around radioactive decay… but time itself can not be measured
kind of like force… it can be measured… but mass cannot… thus making even the concept of mass only theoretical and why quantum physicists have such a hard on for the higgs-boson particle
