   Apr 22, 2024 · While the chances of finding life elsewhere remain unknown, the odds can be said to be improving. A well-known list of the data needed to determine the likely abundance of life-bearing worlds, though highly conjectural, is known as the “Drake equation.”. Put forward in 1961 by astronomer Frank Drake, the list remains mostly blank.

   Jul 14, 2014 · Finding smaller planets, the Earth twins, is a tougher challenge because they produce fainter signals. Technology to detect and image these Earth-like planets is being developed now for use with the future space telescopes. The ability to detect alien life may still be years or more away, but the quest is underway.

   Are We the only intelligent life in the universe?

   • "We live in an infinite Universe, with infinite stars and planets. And it's been obvious to many of us that we can't be the only intelligent life out there," says Prof Catherine Heymans, Scotland's Astronomer Royal. "We now have the technology and the capability to answer the question of whether we are alone in the cosmos."

   Do intelligent life-forms live on other planets?

   • Like other astrophysicists who have weighed in on these sightings, I’m skeptical of their extraterrestrial origins. I am confident, however, that intelligent life-forms inhabit planets elsewhere in the universe. Math and physics point to this likely conclusion.

   Does life develop intelligence?

   • Kipping framed the problem in terms of four possible answers: Life is common and often develops intelligence, life is rare but often develops intelligence, life is common and rarely develops intelligence and, finally, life is rare and rarely develops intelligence.

   Is intelligence possible if we played Earth's history again?

   • “If we played Earth’s history again, the emergence of intelligence is actually somewhat unlikely,” he said. Kipping points out that the odds in the study aren’t overwhelming, being quite close to 50:50, and the findings should be treated as no more than a gentle nudge toward a hypothesis.

   May 18, 2020 · The analysis is based on evidence that life emerged within 300 million years of the formation of the Earth’s oceans as found in carbon-13-depleted zircon deposits, a very fast start in the context of Earth’s lifetime. Kipping emphasizes that the ratio is at least 9:1 or higher, depending on the true value of how often intelligence develops.
