[1806.02404] Dissolving the Fermi Paradox - arXiv.org

Anders Sandberg, Eric Drexler, Toby Ord. View a PDF of the paper
titled Dissolving the Fermi Paradox, by Anders Sandberg and 1 other
authors. The Fermi paradox is the conflict between an expectation of a
high {\em ex ante} probability of intelligent life elsewhere in the
universe and the apparently lifeless universe we in fact observe.

Dissolving the Fermi Paradox

^^^^^

The above paper gives low odds of there being another technological
civilization in our galaxy.  I found the paper reasonable and
accounting for what we see out there.  More or less considered it a
closed issue.

The paper came out about the same time that the odd behavior of
Tabby's Star was discovered.

I was in the camp of it must be natural.  However when they found a
number of other stars in a cluster around Tabby's Star, it seems to me
to be evidence of life spreading from star to star.

Simple analysis of the shadow patterns leads to an object at 7.8 AU
and over 400 times the area of the Earth.  This is not in the
habitable zone, but it does seem to be in the computational zone.
Could we be looking at the shadows of giant data centers holding
trillions of uploaded aliens?  Off planet giant data centers may be in
our future so perhaps that's what happened at Tabby's star and the
other ones that blink.

Good reason to keep you cryonics contract active if you want to know
how this story turns out.
