Still another take on They’re Out There

types of planets Kepler found/NAA

They’re Out There seems really big just now. What’s another theory about why we never hear from them? How about, it wouldn’t really take that long to cross the galaxy. They could if they wanted to:

“The sun has been around the center of the Milky Way 50 times,” Jonathan Carroll-Nellenback, an astronomer at the University of Rochester and lead author of the study, said to Nautilus. “Stellar motions alone would get you the spread of life on time scales much shorter than the age of the galaxy.”Georgina Torbet, “Is the truth out there? New paper proposes solution to the Fermi paradox” at Digital Trends

In one suggested version, they might be Out There but we are not smart enough to recognize them:

“The click beetles in my backyard don’t notice that they’re surrounded by intelligent beings — namely my neighbors and me,” Fermi paradox expert Seth Shostak told Nautilus, “but we’re here, nonetheless.” Georgina Torbet, “Is the truth out there? New paper proposes solution to the Fermi paradox” at Digital Trends

Can’t argue with a proposition like that. Paper. (open access)

Okay but now one question: If none of those 47 planets has life, does that count as evidence against the proposition that “We Are Not Alone”? Does anything count as evidence against the proposition?
