The typical ending of our lovely planet will come in several billion years when the Sun swells up and engulfs all of the inner planets. But it’s never too early to start thinking of how to rescue our beloved cradle.
According to an article in the NYTimes, the Earth faces an unknown future because it will move further out in orbit as the Sun expends its mass and the gravitational forces become weaker.
One solution is to lasso comets and asteroids, swinging them near the Earth and using their slight gravity to boost the Earth to a higher orbit, where it could escape the Sun’s expansion. Because, y’know, what could go wrong with that?
