I recall arguing that we *can* detect microorganisms once the idea occurs
to us, using quite simple apparatus. We can even detect nanobes (forms of
`life' too small, on the face of it, to *be* life - still a goer, according
to an interview on Aussie radio this last weekend,

despite appropriate caution not to say ridicule expressed at the claim here
a year or so back).

Well, that *some* of them surely would, unless they all instantly take
themselves down to the nanoscale, hyper-souped up clockspeed and all, and
remain sequestered in their own navels.

Could well be. I suppose it depends on whether the post-Spike future is
*literally unimaginably strange* (perhaps with `magic physics', etc), or
just *strictly unpredictable in detail* but functioning within today's
rules, more or less (given a better fusion of QT and relativity, say).

I do have a hunch that even more advanced science isn't going to show us
that the Earth is actually a gigantic tetrahedron. Will it teach us rules
of game theory and economics that *altogether* escape the strictures known
to us? Maybe, in which case you're probably right. But if so, the
post-Spike ET cultures are likely to be beyond our cognitive event horizon,
aren't they? So even if they're *there*, you can't get there from here -
*except* via a Spike of your own... Does this disable the Great Filter
model? Dunno. Over to Robin... :)
