There is no [need] to get trapped by any particular idea at all. Because each idea can be treated as an hypothesis or an assumption. If an hypothesis, it can be tested and might not turn out to be valid (i.e. it might not explain the data collected). If an assumption, we can simply adopt another one that we find more useful. Prior to Einstein, people were trapped by the Newtonian idea of absolute [time] guaranteed by the will of God. After Einstein, we learned to see time as relative to other observations: movement and gravity. Einstein’s ideas are not true and Newton’s ideas are not false. They are simply more or less useful from “time to time.”
