Exoplanets ping

[ealgeone]

Somehow gotta feeling we’re not on that list.

[EEGator]

GIGO

[a fool in paradise]

Schrodinger’s cat died because someone neglected to feed it.

[ProtectOurFreedom]

Yep. We were probably on the list until about 1914. Better take us off the list.

They are counting their own toes and extrapolating.

[Robert A Cook PE]

Yeah me too.
Is there intelligent life in outer space?
Is there intelligent life on earth?

[ifinnegan]

How many?

[Repeal The 17th]

From the article:
“...the work relies on a lot of assumptions...”

Understatement of the day.

I like watching the youtube videos of Prof. David Kipping of Columbia University. He’s addressed the topic of calculating the possibility of intelligent life in the universe several times, including a recent video last month:

Earth: 0

[satan]

Did they use the Coronavirus model?

[Harmless Teddy Bear]

Right now, I am going to go with zero.

[ArcadeQuarters]

Of the star systems we’ve explored so far, 100% have life. Extrapolating this, there are approximately 400 billion civilizations in the Milky Way galaxy.

I should mention that Prof. Kipping has himself published papers on this subject, and discusses his latest one in the video I link above.

Westby and Conselice...built a key assumption in to their estimate: Life on another planet will arise in a similar way to how it did on Earth.

Yet scientists have no clue as to how life arrived on earth.

In a finite Universe (or at least one with a marked beginning), someone has to be first. We know we are here. Until there is evidence to the contrary, we are it. The rest is assumption and guesswork.
