Israeli Physicist Says Life May Have Existed Earlier Than We Thought

According to a paper recently released by Israeli theoretical physicist Abraham Loeb, life may have existed in the universe billions of years earlier than originally thought.

Loeb’s theory puts forth the notion that conditions shortly after the Big Bang - which was more than 13 billion years ago - could have produced conditions able to create sustainable life.

Current belief puts the beginning of Terrestrial life on Earth at 3.5 billion years ago.

It is believed that 15 million years after the Big Bang, the universe would have cooled to an approximate Earth-like temperature, notes Loeb. This contrasts the majority scientific thought that life can only arise/exist under certain conditions. The current analyses of exo-planets - planets that orbit stars - involves the search for the “goldilocks” planet - the planet where the conditions are just right for the support of life.

Loeb says that the period of Earth-like temperature would have lasted for about seven million years, which gives rise to the possibility that some forms of life could have evolved during that time. Loeb’s idea runs counter to current theory, which indicates that planetary system had not formed into their current configurations shortly after the Big Bang.

Free-floating rocky bodies or other masses could still see Loeb’s ideas applied to them, as they may have had Earth-like temperatures, and also water, even if they hadn't orbited the sun.

Edwin Turner, astrophysicist at Princeton University, told Science.com that Loeb’s theory was “very original, stimulating and thought provoking.”

Loeb was raised in Israel and received his PhD from Jerusalem's Hebrew University at 24. He's spent the last 20 years at Harvard. Loeb has authored over 430 papers and frequently returns to Israel as a visiting professor at both the Weizmann Institute and Tel Aviv University.
