Does the “hesitation” of light mean, that time is a spatial construction?
Ole Rømer (1644-1710) discovered the “hesitation of light”; that light has a speed. It travels at a speed of 299792459 m/s and not at an infinite speed, as believed until then. But if light has a speed, it must have an extension.
In my interpretation, I erect a pillar of light, by sending a beam of 8,28 minutes length into the universe. This equals the distance between earth and the sun (=one AU; astronomical unit). Somewhere out there, my pillar of light is still flying further away from earth; a monument in space for Ole Rømer.
