Matteo Ceriotti in The Conversation explains the plausible science of the new Netflix film, Wandering Earth (2019).
The science is interesting, but Ceriotti leaves the best for last. If there’s any human life on Earth when the sun starts to expand, the best thing we can do is move the entire population of the planet to Mars.
Personally, I’d much prefer moving to the moon, that way we’ll be floating through space like the team of Moon Base Alpha in Space: 1999.
