Thanks for answering my question. This is facinating, I continue to be
impressed that "simpler" forms of life are so tenaciously adaptable.
Which (if any) of the creatures you know of can survive long term in a
very high vacuum (say, under 10^-9 torr) at 3 degrees kelvin? Presumably,
most all water would be gone. Of course, things might hide inside a rock
for much longer, with the pressure being much higher.
Do you know of any books or papers specifically discussing the survival of
organisms over extremely long time-spans?
