I think this guy is making an existential argument, rather than a physics one.crudus said:By the logic in the first paragraph we could do the same thing with a meter stick. I could get a longer/shorter piece of wood and call it a meter. It really doesn't do anything for me though. What you did what change the way to measure something, not the something itself. It really doesn't change anything. The same amount of time will still pass and the same speed. If you want to change time just go really, really fast or go near something truly massive.XHolySmokesX said:Time is a man made concept, it is not a natural phenomenon. Time was created to allow us to have a grasp of how long something will take to complete, how long ago an event happened or how long it will be until an events happenes. Time is something that can be very easily changed, if i wanted to change the number of hours in a day to 10 and change how long a minute was, with the right knowledge of how a clock worked, i could do it.

Our conscept of time revolves around the length of time it takes for our planet to do a full rotation, and the length of time it takes to orbit our sun once. This would be different for every other planet in the universe, including those in our solar system.
Like, if nobody measures time, can it really exist? It's the old "tree falling in the woods" thing.
It's not something you can really use logic to refute, because it's challenging the entire foundation upon which logical thought is based.
