I think it's being discussed as a result of my upthread joke about
multiplying wavelength by the emitters proper time, and getting
negative energy. This is a joke, because the expression for
relativistic doppler has already taken care of this; I was
pulling a bit of a sleight of concept there.

Like the traditional joke:

Three guests check into a hotel, are charged 10 quatloos each (30
quatloos total) for rooms. The manager discovers a mistake in the
billing rate, and sends the bellcritter with a five quatloo refund.
The bellcritter can't divide the five one-quatloo notes in hand
between three guests, and so pockets 2 quatloos, and refunds 1
quatloo each. So, each guest paid 9 quatloos, the bellcritter
kept two, but that's only 29 quatloos...
what happened to the missing quatloo?

Similar thing here. "The energy would be negative" is sort of like that
missing quatloo. Not an exact analogy, but sort of.


But ANYways... the energy "would be" imaginary, if you naively apply doppler.
And then, if you naively calculate the energy, that's imaginary too.

Or... so I imagine.

But... neither sonic booms or cherenkov radiation in non-vacuum
is really an "emission" to which doppler can be applied in the first place.
Is it? Well, now I'm starting to lose my place here...
