If intelligent life should be common in a universe with hundreds of billions of galaxies, why does the cosmos remain eerily silent? This video explores the famous Fermi Paradox and the Kardashev Scale ...

(via Sabine Hossenfelder) The Fermi Paradox is an estimate that says: Given all we currently know about the universe, we should have found extraterrestrial life already. So why haven’t we? In a paper ...

Astronomers raised hopes that humanity might not be alone in the universe by announcing on Thursday they have detected the most promising hints yet of life on a distant planet. But given the age and ...

Our search for extraterrestrial life has turned up empty, perhaps because technologically advanced civilizations are doomed to fail. An astrophysicist has proposed an intriguing explanation for why ...

The big thinkers at Aperture examine the Fermi Paradox and why we have yet to find alien civilizations. Iran seizes Chinese floating armory near Strait of Hormuz CNN's Jake Tapper calls out Trump's ...

It was a simple question asked over lunch in 1950. Enrico Fermi, the Nobel Prize-winning physicist who helped usher in the atomic age, was dining with colleagues at Los Alamos, New Mexico, when the ...

If we could travel at 10 percent of the speed of light, we’d cross the Milky Way Galaxy in one million years. Presumably, an advanced alien civilization could be doing this already, zooming through ...

(via PBS Space Time) Around 2 billion years ago, life had plateaued in complexity, ruined the atmosphere, and was on the verge of self-annihilation. But then something strange and potentially ...

If life happened here, then it likely happened elsewhere. But as far as we can tell, we're totally alone. So where is everybody? A new analysis proposes an alternative solution to this conundrum, ...

Astronomer Frank Drake formulated his influential equation in 1961 to estimate the number of civilizations in the Milky Way capable of communicating with us. Our understanding of planetary science has ...
