Extraterrestrial intelligence?

[Jehanne]

I appreciate your skepticism.  But, certainly, if we can identify intelligent life on this World (setting all jokes aside), then what's stopping us from doing the same on other Worlds?

Primarily, the fact that we aren't on other worlds.

Astronauts were still able to communicate to the Earth from the Moon, and NASA/JPL is still in touch with the Voyager spacecraft after nearly 40 years of being in space.  The ID proponents are correct in this regard, in that there is such a thing as an artificial signal; they are simply wrong about the fact that such a signal is present anywhere within biology, which is not the case.

Question is, is the data from KIC 8462852 indicative of an artificial signal or can it be explained by natural processes?  Nuclear/stellar physics would be incomplete if something such as a star could vary its brightness by 20%, and there is no reason to think that modern particle physics is incomplete.

But, yes, none of this is evidence; that is not what I am suggesting here.  But, more data, more data, more data, etc., is what is needed.
