Episode notes
There's a time delay from that blob of light relative to all the light around it. But why would you even notice that? Well, you would actually notice it in an image at least some way downstream of your light beam because there's this delay in the light coming out. What a lens does when it focuses is it delays part of the light selectively to the other which gives you some sort of curvature. If we make something 90% invisible, that's probably going to be pretty good or 99%.
