... The experiment clearly showed that the ether does not exist as it did not detected any ether wind because the measured speed was the same in all directions, while the experiment was in principle sensitive to measure the predicted ether wind. The null result of Michelson-Morley experiment can only be ...

But position involves also direction: in principle the object could be to our right or to our left. To include the information of direction we use a vector. The ...

Time dilation
In the theory of relativity, time dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses.An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's own equally accurate clocks. This effect arises neither from technical aspects of the clocks nor from the fact that signals need time to propagate, but from the nature of spacetime itself.
