So yea, i have been thinking about it a lot recently and i thought maybe i could hear some more opinions and ideas about the concept of Time, what is Time? Does it Really Exist?
That is a different thing entirely that happens to use the same name. And in the general world is far more important. Obviously time in the way of 3:00 or whatever is based on the rotation of Earth, and though you might be like me and be thinking who gives a shit, it still has heavily important uses for society as a whole, even if individually it doesn't really matter.
But back on topic: a lot of people also don't understand that clocks don't measure time in the way you're talking. Clocks measure themselves: to calibrate a clock you use another clock.
And I was in a bit of a hurry yesterday, but I was going to say what entropy even was.
Basically things flow from low entropy to high entropy, like a sand castle falls into a sand pile (in itself, entropy represents the amount of energy available for work in a process, but that isn't important). That is really it all there is to it, but that flow is referred to as the arrow of time. So as time goes forward, entropy increases, and can be used as some form of method to differentiate past from future.
For instance, say you build a house. A house is definitely low entropy; so you go back fifty years later. It's fallen apart, everything is in a pile, it's desolate. It has a higher entropy because it's no longer got such a specific organization. Things have fallen into piles (like they do. Physically there is no reason that sand can't get blown into the form of a sand castle, or a wind storm knocks trees over into a house. But they don't do that, they fall into high entropy piles).
That's a very simplistic overview... it gets a lot cooler. In rereading it I realize how boring that sounds.
