Rethinking the Michelson-Morley experience

Rethinking the Michelson-Morley experience

(zenodo.org) According to the special theory of relativity (STR), the speed of light in a vacuum is the same for all observers, regardless of their motion. This means: If one observer is travelling at some speed and the other remains at rest, they will both measure the speed of light as c, regardless of their states of motion. Even if the object is flying towards or away from the light, the light will still have a velocity c relative to it. For classical mechanics such an effect could arise if objects have a wave structure and the speed of propagation of these waves would be equal to the speed of light. In this case the propagation speed would be bound to the notion of some medium. There were earlier attempts to link this medium to the ether. The Michelson-Morley experiment showed that there was no ether. But let's look at it in more detail. Michelson and Morley used an interferometer, a device that measures the...
