Entropy - "A process of degradation or running down or a trend to disorder"
"The degradation of the matter and energy in the universe to an ultimate state of inert uniformity"
In other words in my own words everything within this universe is in a constant state of evermore chaos and continuously breaking down into eventual nothingness...
So time must be entropic as well?
But what would time really be and what would time actually mean if we eliminated all of our clocks and watches and calendars and stopped living enslaved by them?
Is time really anything more than our human way of trying to structure and give order to the changing seasons and the days and nights of the rising and setting sun and moon?
I like this post! Time is a strange one... In answer to the question in the last paragraph, I guess yes and no. There are two aspects to the time we perceive, you've already discussed both of them, it's about making a distinction between the two.
We have real time (the decay of entropy as you rightly stated) and our 'imaginary time' based on our orbit around the sun. The problem being of course that or calendar and clocks are consistent, whereas our view of real time is changing based on our waking experiences and even due to extreme gravity/speed. If you read any of Hawkings major publications, he discusses this subject in depth and gives examples of experiments in the past which have proved entropic time and our clocks work differently. Building a clock that measures entropy would be impossible however, especially considering time works differently at different points of the earth. For example, If you find the area of earth with the highest gravitational pull, your experience of 'real' time would be different to that of someone living on the area of earth with the LEAST gravity. After a while, these two places would show different times entirely.
So yes, time is real, but clock time, we invented. However we do need the clocks in order to reference when things happened along our timeline (when people talk of time as a dimension, this is what they mean. A dimension just means direction with which you can name a co-ordinate. Think of our X, Y and Z axis in a 3 dimensional universe, with these 3 axis we can mark any place within a 3D structure. But if you want to mark an EVENT, you need the time co-ordinate too. You can't relay when something happened just using spacial dimensions.
It's all pretty incredible!
