Very much agreed on the social part of the subject, though, time can be made to measure a hell lot of things. originally, it was a simple variant to calculate the phases of a day, then it evolved and evolved and nowadays, it can be literally what everyone perceives it to be, for me, it's a mathematical term for a hypothetical multiplying vector that starts it's movement - and branches - only forwards, then ends as inevitably as it began, we could simply call it life, but that would be under-measuring it.

I've discussed the subject with a friend of mine recently and concluded that there should be two more hypothetical vectors, if we're talking about life, one would have to be "Will" as in the all-encompassing mindset to a certain individual's actions, the combination of his experiences, perspective, thoughts, evolution, emotion and then the arbitrary variant, ya know, sometimes you just decide on something fairly random and go with the flow. As for the second vector, which I call "Act" is pretty self-explanatory, it's the manifestation of one's mindset and randomness in the form of actions or decisions.

The end-product of the collision of decisions and actions or simply of mindsets is what we call a dimension, and there can be no more dimensions of this singular universe unless at least a single individual had two or more minds and bodies, and then, only he can see the differences and that would, hypothetically speaking, make dimensions purely a matter of perspective.

Then comes time, the third vector - vector, because we theorized that time was non-existent and started at some point and since the universe hasn't ended then it's a vector - in life, the one remarking the passage of life from birth till death, t'is also a line, because, for one, the "start" of time is only hypothetical, it could simply have been, is and always will be, and while almost everything ends, one of the main things we haven't seen ending, rather, expands, is the universe. it can be a sphere as well - a sphere of possibilities!

Time is both objective and subjective, depending on how you look at things and what our ever-incomplete knowledge allows, and I could go on for days trying to write my ideas of it, so i'll just wrap it up with a quote of a man with the mind of a god, yet he still worshiped one.
