Here are some conceptual questions and I'd love to hear your opinions on it, because there are quite a few of them, so I decided to post the question one at the time. 1) Is motion possible without time? Is time posssible without motion? Is time possible without change? In my opinion, motion and time coexist. I believe time is an abstract concept created to measure how "things" change within a parameter relative to a specific coordination. The "change" relative to the parameter is caused by motion. Hence, if time doesn't exist, there would be no change, and if motion doesn't exist, there needn't to be the concept of time. Therefore time and motion must coexist.
