Elon Musk recently raised eyebrows by stating that "eventually, all life on Earth will be destroyed by the sun." This bold claim echoed the findings of scientists from NASA and Tōhō University in Japan. Using cutting-edge supercomputers and mathematical models, these researchers have projected significant changes in our sun’s lifecycle.
Their calculations suggest that life on Earth could become impossible by the year 1,000,002,021. As the sun gets hotter and brighter, global temperatures will rise, leading to lower oxygen levels. Eventually, this could trigger a mass extinction event.
In about five billion years, the sun will enter its red giant phase, expanding dramatically and likely engulfing the inner planets, including Earth. While this future may seem distant, it underscores Musk’s ambition to colonize Mars. He describes Mars as "life insurance for life collectively," emphasizing the need for humanity to establish a multi-planet civilization.
NASA estimates that the sun is still less than halfway through its lifecycle, with about five billion years left. Researchers conducted over 400,000 simulations to understand how climate and gas compositions might change over time, as detailed in a study published in Nature Geoscience. They found that as the sun’s brightness increases, Earth’s climate will become unstable. Oxygen-producing organisms will decline, ultimately leaving behind anaerobic microbes that can survive without oxygen.
Musk is eager for Mars to become self-sustaining within his lifetime. He views this as a turning point for humanity’s fate. If Mars can thrive independently, it would assure our survival despite any catastrophic events on Earth.
It’s also worth noting that Musk’s ambition aligns with historical shifts in space exploration. The Trump administration once cut NASA’s budget, impacting projects like the Mars Sample Return mission. However, Musk’s quest for Mars remains a priority, with the goal of leading human space exploration and making interplanetary life a reality.
As we ponder the future, the conversation about space colonization isn’t just about distant dreams—it’s about ensuring survival in an ever-changing cosmos.
