About :
This isn’t a DVD floating in space. This is a megastructure that could one day be home to humanity. It’s possible that Earth won’t remain habitable forever. It could be swallowed up by a solar flare, become too hot due to climate change, or have all life wiped out by a giant asteroid. What if I told you that we could survive all of these disasters? And that we would do it by building a megastructure in space that was bigger than the Sun itself? How big would it have to be? And what would it be like to live in something like that?
