They doubt that there is life on other planets – Voice of America

Australian researchers say life in planet newly born possibly “become extinct due to unstable weather.”

Although the universe is full of habitable planets, life on any of them would die quickly, say scientists at the Australian National University.

New research suggests that while the universe is full of habitable planets, living in any of them would die quickly.

An article by Australian researchers in the journal Astrobiology says life on a new planet possibly “become extinct due to unstable weather.”

Scientists at the Australian National University, ANU, say many researchers believe that if a planet is habitable is full of aliens. Aditya Chopra, an author of the report, said that “the first forms of life are fragile because what we think is rarely developed enough to survive.”

expert notes that the main reason is the lack of stability. “Most of the new planetary environments are unstable,” says Chopra. “To produce a habitable planet, living beings need to regulate greenhouse gases, water and carbon dioxide to maintain stable surface temperatures”.

As an example of this points to Venus and Mars that could have been habitable at some point, but too heated first and the second is practically a freezer.

The study co-author Charley Lineweaver, Institute of Planetary Sciences at ANU, says any basic form of life on Mars or Venus could not help stabilize the atmosphere. “Life on Earth probably played an important role in stabilizing the world’s climate.”

Chopra agrees with the statement and said that “the mystery of why they have not found signs of extraterrestrial has less to do with the origin of life or intelligence to the rarity of the rapid emergence of biological regulation of feedback loops on planetary surfaces. “

The research also explains the paradox Femi, which It states that despite the high probability of the existence of habitable planets, has not yet found signs of extraterrestrial life.
