One comment about the Time concept (listed above). Scientific time is one conception of time. There are many other concepts of time.
For example, when we are doing something we enjoy time tends to “go faster” and the opposite may be perceived true when we are experiencing something we don’t enjoy (like suffering pain for example). This may lead us to think that at least our experiential perception of time is somewhat “flexible”.
There are other cultures that have their own concepts of time. I think we need to take into consideration all theories of time before we can “answer the question of time”. It really has many answers.
From the scientific perspective how do we explain the different “branches of time”existing simultaneously through black holes?
How do explain the possibility of “branched time” when we consider the theory of the multiverse, (the scientific concept that we are spawning multiple universes continuously).
