Musk warns that solar expansion threatens - calls for the establishment of a multi-planet civilization.

Elon Musk recently issued a warning, pointing out that the gradual expansion of the sun could pose a threat to Earth, and emphasized the need for humanity to become a multi-planetary civilization to ensure survival. Musk, discussing the future of the sun, stated that over time, the sun's expansion will eventually engulf Earth, leading to the inability to sustain life. Musk said, "One benefit of Mars is that it can provide collective life insurance for all life. Eventually, all life on Earth will be destroyed by the sun. The sun is gradually expanding, so we must become a multi-planetary civilization, as Earth will eventually be burned up." As the leader of SpaceX, Musk has repeatedly stated that Mars is a "backup home" for humanity and actively promotes Mars colonization plans. He believes that with advances in technology and ongoing space exploration, humanity may be able to establish self-sustaining societies on Mars and other planets in the future, thereby safeguarding the future of humanity.
