“It will not be eternal”: The end of life on Earth already has a date and will be due to a lack of oxygen

Previously, A Deep mystery Yes, there will come a day when life ends, but that is a reality now. According to a study published in the journal nature, he Oxygen In the Land It will run out at some point. That is why it is necessary to make an effort to find it Planets that can accommodate human life, Because, unfortunately, in the future it will be necessary to have a new place.

The researchers are led by an ecologist Kazumi Ozaki Predict the evolution of our gases Atmosphere Modeling Climatic, biological and geological systemsWith nearly 400 thousand simulations.

A combined model of biogeochemistry and climate was used to study the potential time scale of carbon-rich atmospheric conditions. Oxygen On the ground, details of the study.

In turn, they took into account changes in sunrisedifferences in Carbon Dioxide And the changes therein Terrestrial biosphereTo reach the conclusion that our planet will be abundant Methane Finally, Oxygen.

The question everyone is asking now is: Is it that far? When will that happen? Fortunately, the response is encouraging, because it will take effect Billion years.

It’s not déjà vu, the future repeats the past

Now, this configuration of Deoxygenated atmosphere Nothing new. According to the study, Land You have already gone through a similar phase known as obsolete (or the ancient era) where Atmosphere Lacking Free oxygen. This dates back to approx 4 billion years.

But then the call came The great oxidation event (GOE), where oxygen levels rose sharply, thanks to the appearance of the first Optical objects able to produce OxygenDo 2.4 billion years.

currently, Oxygen forms around it 21% of the atmosphere terrestrial, and makes life possible for large and complex organisms, such as Humans. But the worrying thing is that It won’t be eternal. “We have discovered that the Earth’s atmosphere is full of oxygen “It will not be a permanent advantage.”Ozaki said.

The main reason for the expiration of oxygen is the process sun aging, That over the years it will become hotter and emit more energy. This will lead to a decrease in Carbon Dioxide In the atmosphere, carbon dioxide decomposes by absorbing heat. “We’re talking about a million times less oxygen than there is today.”

Scientists concluded that Removal of oxygen The research confirms that the future is an inevitable result of increased solar fluxes.

Regarding searching for Habitable planets By humans, researchers point to the need for tracking Biological signals Other than oxygen to increase the chances of infection Life revealed. This analysis is done in the project NExSS (Nexus for Exoplanet System Science) Subordinate a potIt is responsible for verifying the validity of housing in Other planets Apart from our country.
