Some 5 billion years from now, the Sun will expand and become a red giant. And Earth might be just in the way... If humans were still around then, would we leave Earth? Or would we move it? What is the Sun's problem anyway?
Like any other star, it has an expiration date. The beginning of its end will feature our Sun swelling into a red giant, wiping out everything that happens to be orbiting it too closely. Like Earth.
Produced by Underknown in Toronto, What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure — grounded in scientific theory — through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.
