As I understand it, You're traveling at the speed of light. You have your perception of entropical change and an observer has theirs. There is no singular time that "exists". There are multiple perceptions that "exist". Time itself is not existing, as much as it is a perception of process(es). Humans mark states and compare later. This is not time, this is a measure of states. The term time is a shorthand for that, to the detriment of comprehending/understanding what it (the term Time) is describing.
