Could Planetary Warming Hold the Key to Understanding the Fermi Paradox and the Absence of Alien Civilizations?

There have already been several explanations for why the universe seems empty to us, when, according to mathematical probability, at least ten thousand fully developed alien civilizations can only exist in the environment our cosmic, the Milky Way. Many hypotheses, including the famous one Fermi paradox In addition, now another theory is trying to find an explanation for why we do not find signs of aliens. AN planetary warming may be the key.

How many years will it take for a planet to destroy itself?

According to a new model, it would take less than 1,000 years for an advanced alien civilization to destroy its own planet through climate change, even if it relied solely on renewable energy. When the astronomers who compiled the study simulated the reasons for the rise and fall of alien civilizations, they concluded that if a civilization experienced exponential technological growth and energy consumption, it would take less than 1,000 years for its ‘ alien planet become too hot for life. . that it is possible wait

This would be true even if the hypothetical alien civilization used renewable energy sources, due to the inevitable heat trap as predicted by the laws of thermodynamics. The new research was published on arXiv into a pre-publication database and is currently under peer review.

Planetary warming: what causes it?

While astronauts were trying to understand the environmental and civilizational effects on extraterrestrial life, first human energy use they encouraged their research, which has grown significantly since the Industrial Revolution, ie the 1800s.

In 2023, humans will have used about 180,000 terawatt-hours (TWh) of energy, which is about the same amount of energy that reaches Earth from the sun at any given time. Most of this energy on Earth is produced by gas and coal-fired power plants, at an unsustainable rate. warming the planet. But even if all this energy were produced from renewable sources, such as wind and solar energy, due to the continued growth of humanity, more and more energy would still be needed.
