[ExI] [Extropolis] Terasem Space Day Colloquium, July 20, 2023

[Keith Henson]

"explain what we see?"

It was just to answer your comment about dust.  Something can look
like dust from a distance and still be an intentional product.  Non
Tethered dust just does not work because the time before it gets blown
away is so short.

I hope you are right and there is a natural explanation for what we
are seeing.  Neighbors who can block substantial fractions of the
light of a star do not bode well for the human race or our AI
successors.

If you have a natural explanation for what we see with Tabby's star
and the other nearby slow dippers, please let us know.  If you need
motivation, solving this question will considerably increase your
status.

But the thing that kills the alien megastructure theory dead as a doornail, at least for me, is the finding that there is less dimming in the infrared than in the ultraviolet, because there is no way that could happen if the dimming was caused by anything larger than dust particles.
