How do you personally measure time?
What I think time is.
Time is something that we can not completely comprehend. Time, to us, is only a means of measuring the 'time' that passes through an infinite series of events, but this is not what time really is. Time is just a way of getting society to function according to day, midday and night. The hour, year, second and other units of time are just the creation of humanity. Time is actually relative to our position, therefore there is no such thing as a set definition or parameter of time. When saying relative, I do not only mean from our position with Sun and Earth, but the position of us on Earth to the universe itself. The sun is expanding little by little, and I am not sure if this is why we do this, but each 'year', we must increase the time for a year by a certain amount of time (I am not so sure about how much time.). Yet, what about the accelerating expansion of the universe? How can we be able to measure the relativity of our position with a universe that is continually accelerating? I do not think that we can make an infinite change in our calculation in position, which results in the change in what absolute time is. I do not think that any human can do so. Therefore, because there is practically an infinite relative positions you can measure from in accordance to your position of time, it really is impossible to determine an actual definition of time because there is no actual time.
Also, if one were to consider the relativity of time to the wholeness of time itself, one could consider that time never actually does pass. For example, if the beginning of everything was never defined at a set point, then we can designate this as infinity (the past). Any time that is limited (ie. 500 years, 2 seconds, according to our time) divided by inifinity would result in zero, thus implying that no time or almost no time has passed.
Again, this is just a possible theory that came through. Please feel free to disagree.
