You and the passenger disagree on the distance the light traveled, but not on the speed of light (since it never changes). Speed is distance divided by time—meters divided by seconds in this case. The difference in distance you and the passenger observed the light travel is really a difference in how much time passed. This is Einstein’s theory of relativity. Time is not absolute; it is relative. Both you and the passengers have your own different measure of time. “The distinction between the past, present, and future is only a stubbornly persistent illusion,” said Einstein.
Measure this distance from the concave mirror and mark it in several places around the tube. Connect the marks so there’s a line all the way around the tube. Is your tube a lot longer than this mark? It only needs to be a few inches longer, so you can cut it down if desired. Set it aside. 7. Cut along the entire length of one of the smaller cardboard tubes.
