| About the incompability of the definitions of time:
It can be said that there are two main definitions or meanings of the concept of time. Exluding the ideas of time as not being real but human creation or just something that humans measure.
The first definition is that time is a dimension. What basically determines something of being a dimension is that it must have two directions (or two degrees of freedom) and be esential for existence. For me to exist, I need space. Space standing for the three spatial dimensions. But I also need time, because if not there is no existence for proving my existence. Thus, to exist we need space and time (space-time). I want to note that these are the regulations to existence and existence only. To live or others there are additional conditions, but this isn't the apropiate thread.
The second definition of time is that it is motion. Although in many ocasions this is not completely an exact answer: some say that it is caused by motion, other that it causes motion..... But the agreement is that there is a conection or relationship between time and motion. Motion is the change in points of space.
The major point, I think, between these two definitions of the concept of time, that makes them incopatible is that: The first one concludes that time and space are obligatory and mutual dependent. Whiles the first one states that only space is needed for existence because time is just the difference in points of the first one, and there is no need for having a change in space to exist, justo to "be" or occupy space.
Conclusion: Time as a dimension and time as motion can't and should not be dualised to explain or define the abstract concept that time is. Space and time are needed for existence. There can be existence without change/difference in space.
Extension: We should try, now that it is clear and proved that time can't have both definitions, to decide on which is the best definition of time. But I have a very good point after this.
The actual meaning of this thread and all my posts on time is to make the ones that have followed them, come into the conclusion that I have come into. Although I think that if you trully follow my posts, or you have already dedicated to investigate about time, you will have already come into the conclusion that I came to.
ps: I will post the conclusion in this thread.  |
