Subject: Re: Wacky World of Lightspeed
This "lighthouse" experiment has been evidenced many times by using an oscilloscope and adjusting the angle of incidence of the stream of electrons to a sufficiently narrow angle to geometrically increase the trace across the oscilloscope screen "above the speed of light".

As there is nothing but a concept moving across the oscilloscope screen, no laws of physics are violated. Each individual electron, (if we can refer to them as such), violates no cosmic speed limits.
