Ya that drum bit was a joke. I am trying to cut down on the {8^Ds.
Eliezer and more serious, focussed crowd are filtering me. {8-[
I did have an idea tho. Consider all the dark matter out there. We
think we could detect a Dyson Sphere by the low frequency radiation
that would need to be emitted by reason of conservation of energy.
But what if... the universe is a dangerous place? Then any ETI that
has any brains knows to hide. Could not a really advanced ETI build
a Dyson sphere, then somehow collect the waste energy, collimate the
radiation into a narrow beam and focus it out in some harmless (starless)
direction? Are there SF stories based on this explanation of dark matter?
Given enough raw material, it seems that a really out-there nanotech
civilization could make a sphere and keep its surface at 3 kelvin, so
that it would be undetectable by us less advanced (and therefore more
dangerous) intelligences. Do we have any thermodynamics experts
out there who can confirm that such a scheme does not violate the
third law? Seems to me it doesnt. spike
