Why is time considered non-linear?

Question

Is Einstein's time equation Reflect the non-linearity of Time?

Answer 1

Time is just how we measure motion - we measure the motion of things with time, but we also measure time with precisely defined motion. The mechanisms we use to measure time are based on some type of motion, weather it's a sun-dial (motion of Earth relative to the Sun) or an atomic clock (motion of an oscillating cesium atom). From this it's easy to see how 'time' can be non-linear - the relative internal motion of the time measuring mechanism slows down as the overall speed of the device moves faster.

Einstein's theory of relativity /mathematically/ describes the relationship of 'time' vs speed. This aspect of relativity has been proven using two atomic clocks - one on Earth and one taken in orbit on the space shuttle. In this experiment, the clock on the space shuttle was shown to have run slightly slower while in orbit.

Answer 2

The time it takes to complete something is based off of how fast you were moving as you did it. something like t'= t/ Squareroot(1-c^2/v^2) therefore its never constant. But in everyday life, the change comes out to less than a fraction of a mil-a-second. I dunno if the theories are related.
