It might sound like something out of an apocalyptic movie, but a supercomputer has predicted the end of the world.
But don’t worry too much because it’s not supposed to happen soon.
According to an April 2025 article in LaGrada, a group of scientists used a supercomputer to “determine that survival on planet Earth will be impossible in about 1 billion years, when conditions become too extreme for life as we know it.”
On May 6, 2025, BGR reported that scientists with NASA and Japan’s Toho University used the computer to determine “when all life will end” on Earth. They determined that the sun will end life on Earth around the year 1,000,002,021 because it is expanding, BGR reported.
According to BGR, the researchers found that the sun will grow hotter, with “its output will continue to increase, gradually heating the planet beyond the threshold of life.”
Scientists have studied Earth’s eventual demise for years.
Research published in Nature Geoscience by Kazumi Ozaki and Christopher T. Reinhard in 2021 explained Earth eventually won’t have enough oxygen in its environment to sustain life.
“Earth’s modern atmosphere is highly oxygenated and is a remotely detectable signal of its surface biosphere,” those researchers wrote. “However, the lifespan of oxygen-based biosignatures in Earth’s atmosphere remains uncertain, particularly for the distant future. Here we use a combined biogeochemistry and climate model to examine the likely timescale of oxygen-rich atmospheric conditions on Earth.”
The researchers noted that having enough oxygen in the atmosphere is not a “permanent” state for a planet, so their findings have “important implications for the search forlife on Earth-like planets beyond our Solar System (for example, habitable planets with abundant liquid water at the surface, exposed silicate crust and a biosphere with oxygenic photosynthesis).”
