Considering that time is relative, then we can measure the speed of time, technically. If you measure your own time speed, you'll always find the same result. That's why I said that time is relative. The speed of time unit can be s/s: seconds(observed)/seconds(observer). or simply t/t if you rather. 1.3 s/s 1.2 s/s 1.1 s/s 1 s/s - If you try to measure your own speed in time, you'll always find this result 0.9 s/s 0.8 s/s ... 0 s/s - The speed of time of light in a vaccum. Light doesn't age, as we already know. Keep in mind that all these speeds are relative to the clock of the observer. Does this make any sense? Can you make it better? Comment.
