Asteroids, nuclear wars, and eventual pandemics could accelerate the extinction of life on Earth.
The end of the world is a topic that has fascinated mankind for centuries. From religious prophecies to scientific theories, there are many different ideas about how and when the end could come. Among these hypotheses, the one with the greatest consensus is the one that estimates that the Sun will expand and possibly swallow the Earth in about 5 billion years.
However, due to climate change, eventual nuclear wars, and increasingly lethal future pandemics, the feared end of the world could come much sooner.
According to artificial intelligence, the end of life as we know it, the extinction of species and the destruction of the Earth, would occur in about 100 million years, or approximately 36,500,000,000 days (thirty-six thousand five hundred million days).
From a scientific perspective, artificial intelligence believes that the extinction of mankind could also be accelerated by asteroid impacts. Although the probability of a catastrophic impact is low, it cannot be completely ruled out and for years NASA has been monitoring near-Earth objects and working on deflection strategies.
As for the dangers of climate change, AI warned that if drastic measures are not taken to reduce greenhouse gas emissions, extreme weather events, famines, droughts, and wars could occur, which could lead to the extinction of humanity.
Indeed, a full-scale nuclear war could destroy human civilization long before the estimated date, even in the next few centuries. And a pandemic with a high mortality rate could devastate the world’s population.
On the other hand, if none of this happens, there are approximately 1 trillion 800 billion days left until the end of the world, if we take into account the eventual expansion of the Sun.
This is a long-term process, and the star is expected to increase significantly in size and brightness as it consumes its nuclear fuel. The Sun will transform into a red giant, expanding to the point of engulfing the nearest planets, possibly including Earth.
This scenario would only be possible in approximately 5 billion years (1 trillion 800 billion days).
