[ExI] [Extropolis] Re: Google Alert - Tabby's Star

[Keith Henson]

The thing that kicked me over from "don't know, but it must be natural" to
"it is aliens" was the astronomers finding 24 blinking stars in a cluster.
The closest one is 511 lightyears from here.  That set me off looking at
how big the blocking object was and how far out from the star it was.  The
only thing that makes any sense is a data center for uploaded aliens.  The
reason it is so far out from the star is so it can run cold which reduces
the power and keeps down the errors.

Even that far out, it still intercepts a respectable amount of light,
around 1.4 million times as much energy as the human race uses.

The AIs estimate they have been in space for 3000 years.  I would guess
longer given the distance between stars.  But how low are the odds of
another civilization in our backyard?

I need to run that question by Anders.
