I would like to share an idea with you, and ask what you think of it. The idea concernes our concept of time, and simultaneity of events.
Let me define an observer, as a person which has an ability to “measure and observe” reality (semantic definitions of these terms are difficult, and I hope we share them – if not we can clarify later)
Let us consider a few observers, in separated isolated systems. Lets firstly assume that none of the observers has any ability to memorise, or store information (on conscious level).
Would these observers be aware of the passage of time?
Lets give them the ability to be aware of the passage of time then. That can be only done if they can remember “moment n” and “moment n+1”, and realize the sequentiality of these moments. The observers would need a mechanism for storing and withdrawing information to do so (something like “memory” would probably suffice)
Now that the observers are aware of passage of time, they can build a concept of “past”, “present” and “future” based upon the information they stored. Past would be “time” they stored information about in the moment n-1, “future” would be time they do not have any information about, or the moment n+1.
Each of those observers perceives the moment n as “present” and produces the past and the future. The past, present and future are related by the concept of “time” arising from the sequentiality of stored information.
Can it be said, that the present of each of those obsevers is, on an objective level, happening at the same time?
Time in its own sence of relitivity is a trick. Time only exists because we believe it too exist, time is only a concept created by humans to judge the distance of memorable instances. For example i am currently at my home in Canada it is 5:58 pm , you could be in africa which would mean your time could be lets say 2 am. But the way i perceive a second differs in no way from the way you perceive it. What you are saying in theory is a correct statement, BUT only in the case of a man who has just gained the ability to perceive time.
