how exactly do lasers work?
i know there are many kinds of lasers, but why can't you shine a light in a sphere with the inside as a mirror, then leave a hole and put a long tube on the hole, so the rays going sideways won't escape
i hear that the light just won't stay inside the sphere. it won't "build up"
why won't mirrors really reflect light. not just to some degree.
