The size of the universe

Apparently. But if you ever get involved with RADAR, waveguides etc you'll be told how the pattern of the energy in the waveguide is set up prior to the transmission. As the pattern covers more distance than the path of the energy the pattern must be established faster than the speed of light. A physical impossibility since the speed of light is fixed.

But this is where it gets interesting. A pattern is not physical, has no mass. For me by definition light must has some mass otherwise why would the speed of light be limited?

As it happens I was an electronic engineer working on radar many years ago, and we did know about interference patterns apparently travelling faster than light.

The lecture we got was, don't, but sir what if... don'T ask! Don't ask ever! Even since I've done nothing but ask questions.
