Can We Engineer The Sun?

Video Description

The Sun is dying. A slow death, to be sure, but slowly it creeps towards its end, gradually increasing in luminosity - an effect that will push Earth out of the habitable zone in about a billion years. Can we somehow stop this from happening? Can we save the Earth? Can we save *the Sun*? Join us today as discuss a new research paper from the Cool Worlds Lab at Columbia University, that may help our distant descendants buy themselves billions of years of new life. Written and presented by Prof David Kipping and Matt Scoggins (Columbia).
