Elon Musk has warned that the sun will eventually destroy all life on Earth, with scientists predicting when this catastrophic event could occur. Research from NASA and Tōhō University suggests that by the year **1,000,002,021**, the sun will become too hot and bright, making Earth uninhabitable due to plummeting oxygen levels. In about **five billion years**, the sun will enter its red giant phase, expanding and potentially swallowing Mercury, Venus, and possibly Earth.
Musk emphasized the need for humanity to become a **multi-planet civilization**, calling Mars “life insurance” for survival. NASA confirms that while the sun will eventually exhaust its energy, it still has around **five billion years** left in its lifespan. Until then, space exploration remains crucial for ensuring humanity’s long-term survival.
