Imagine that there is a cube box that has mirrors all 6 faces in . If we use a strong laser and enter in the box from a small hole on the box. The laser light travels in the box long time that we can detect the laser via a detector on other hole of the box.
1) Is it possible to simulate the long light travel in it (for example a day or week)? 2) Is it possible to proof that there is no ether via that box? If we move the box in a fixed velocity what we can observe about receive time on detector.
I ask a question first time in this website If it is asked question or not appropriate for your format sorry for that.
