Interesting Speculation on the Fermi Paradox


I have two major interest; The first is the hard question of what is consciousness; and the second is where are all the aliens?

This Galactic Colonization video I found that discusses a recent paper: The Fermi Paradox and the Aurora Effect: Exo-civilization Settlement, Expansion and Steady States.

What I found useful is the analysis of the confounding variables and the possible solutions to explain what they call, "Fact A:" why we haven't met aliens or found signs of them visiting Earth.

Tagging Dr. Brin who may have an opinion on this?

    If we accept both extreme answers as possibilities (no aliens anywhere, aliens already everywhere) it stands to reason a middle ground would also be possible. Neat to see that middle ground illustrated.

      It was. I see a lot of more outre proposals that have exponential expansion running unfettered across the galaxy, and this seems a more realistic paradigm that defines the bounds of what is probable.

    I wrote an article on the Fermi paradox for the Baen website. I looked at it from a biologist’s, rather than a physicist’s perspective.

      I remember that article. I just went and re-read it again now.

      I think we would disagree very little over the numbers, about the only difference would be some of the constraints, and my favourite: space is big, very big etc. cue Douglas Adams.

      Anyway, thanks for commenting John. Stay well.
