Incidentally, while you can extract only half the power from a wave with
a perfectly efficient antenna, it is possible to extract *all* the power
from a wave. An anechoic chamber extracts essentially all the power from
waves generated within it.



As well, the universe, in all it's vastness, eventually "...extracts
essentially all the power from waves generated..." by _any_ source. HI!HI!


No it doesn't. Free space can't extract any energy whatsoever from EM
waves travelling through it. Consider :-
The cosmic microwave background hasn't had it's power extracted by
the universe in all the time since the big bang. Conservation of
energy applies everywhere.

Just my opinion ;-) but it's allodoxOphobia.

True so far, but just you wait till the *BIG CRUNCH*. You don't
really think that our present Big Bang was the first one ever,
do you? :-)

Suppose that in a time line of infinite length, with no beginning and no
end, there are really no unique events? Everything repeats sooner or
later, does it?

Anything which repeats itself is amenable to Fourier Analysis.

If there's a once-only event then Heaviside's Operational Calculus is
appropriate.

It's not more difficult. It's just a matter of getting used to it.

Sheeesh ! "Fourier Analysis of the universe". Now that's HEAVY!

I'll take a pass...

No! Fourier analysis of the universe could improve the S/N ratio of
Usenet--get all the cranks to go away until they've evaluated the integrals....
