whereiswaldo's Journal: Time

One of my comments regarding what Time is that I think is interesting: :)

If we are just being "timesliced," then an outside observer could exist in the same time dimension, but that's a very strange and specific case, and it doesn't really address how time works anyway. (because you haven't examined the underlying time dimension at all.)

There is no time dimension: time is our perception of change. Our most accurate clocks are based on the rate of decay of an atom, or the rate of spin of an electron. A wind-up clock simply runs at a speed that we have determined will keep a reasonable account of time relative to other clocks. Time does not really exist - but it is useful for us to think of "time".

What does exist is change caused by the operation of our universe. Those outside our system could measure the number of cycles our universe has run for. It's a simple quantity.

I'm not a scientist, but something tells me what is time can't be measured by us because we are inside whatever makes everything tick. Only those outside our system could measure the time inside our system. I would liken it to a computer program: it can't tell when it's being timesliced by the operating system, and it seems like it is running seamlessly, but it is not.
