Across astronomy and astrobiology, a quiet but profound shift is underway. Instead of assuming the galaxy teems with ...

A popular model of evolution concludes that it was incredibly unlikely for humanity to evolve on Earth, and that extraterrestrial intelligence is vanishingly rare. But as experts on the entangled ...

When scientists describe “Earth-like” planets, the phrase often brings to mind worlds scattered across the galaxy, quietly ...

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...

The evolution of humans on Earth may not be entirely exceptional. That is because intelligent life is likely to form if certain planetary conditions are met, a new study suggests. This idea displaces ...

A new model increases the probability of intelligent life elsewhere in the universe, upending the decades-old “hard steps” theory that intelligent life was an incredibly improbable event on Earth. Are ...

How can we determine if intelligent life exists in our Universe, or maybe other universes? This is what a recent study published in the Monthly Notices of the Royal Astronomical Society as an ...

Imagine if the genetic deck had been shuffled slightly differently as some of the earliest life forms began their evolutionary paths. Might a creature just as smart as us -- or even smarter -- have ...

Forbes contributors publish independent expert analyses and insights. Dr. Lance B. Eliot is a world-renowned AI scientist and consultant. In today’s column, I explore a fascinating proposition about ...
