[extropy-chat] Dark matter and ET

[Dan Clemmensen]

Thanks to Robin, Daimen, and Elizier for the pointers to Robert's work. 
Apparently,
I was off-list during much of this, and not paying attention for the 
rest. :-) 

I just read one of Robert's essays:
http://www.aeiveos.com/~bradbury/MatrioshkaBrains/WSGD.html
He focuses on individual stars going dark, how this would happen, why we 
have been
biased against noticing, and how we could notice if we tried. In this 
particular essay he
does not relate this to either the Dark matter problem or the Fermi 
Paradox. It's possible
(even likely, given Robert's background) that he already considered both 
questions and
their relationship to his thesis.
