Sun expanding gradually, will destroy all life on Earth: Elon Musk
SpaceX CEO Elon Musk said in a recent interview that the Sun is "gradually expanding" and it will "destroy all life on the Earth". "So we do at some point need to be a multi-planet civilisation because Earth will be incinerated," Musk stated. "Mars is sufficiently self-sustaining and can grow by itself if...resupply ships from Earth stop coming," he added.
