Fermi Paradox & Great Filter

The cluster centers on discussions of the Fermi Paradox, questioning the absence of evidence for extraterrestrial civilizations despite the vastness of the universe, and the Great Filter hypothesis as a potential explanation for this silence.

Still unlikely, see the Fermi Paradox and The Great Filterhttp://waitbutwhy.com/2014/05/fermi-paradox.html

Yeah, they're probably right: https://en.wikipedia.org/wiki/Fermi_paradox#Great_Filter

Three topics you might enjoy:Drake's Equation [0], the Fermi Paradox [1], and the Great Filter [2].Drake's Equation basically tries to guess the number of civilizations in our galaxy by multiplying the rate of star formation, the fraction of stars with planets, the average number of planets that could support life, the fraction that actually DO develop intelligent life, the fraction that develop a method of communication that sends signals into space (such as radio), and the leng

You're probably thinking of the "Great Filter"https://en.wikipedia.org/wiki/Great_Filter

This is the kind of question that makes me believe in the Great Filter¹.¹https://en.wikipedia.org/wiki/Great_Filter

I'm fairly sure you know this already, but you just described the Fermi Paradox. [1] And the answer to this paradox is that there is no answer, though there are a million hypotheses.[1] - https://en.wikipedia.org/wiki/Fermi_paradox

Is this a Fermi Paradox explanation?

akman Jun 2, 2016 View on HN

Fermi's paradox is relevant: http://waitbutwhy.com/2014/05/fermi-paradox.html Maybe Bostrom's option 1 happens due to the Great Filter...

This is a very optimistic view, but there are plenty of theories claiming otherwise. Check out the Fermi Paradox [1], or the Rare Earth Hypothesis [2] for a more detailed view on the problem.To be honest the easiest explanation for the Fermi Paradox is that we are indeed alone as an inteligent civilization. If we were just an average civilization there should be plenty of evidence of more advanced civilizations across the galaxy, because probabilistically they would be millions of years more
