This is not some DVD floating in space. It's a megastructure that might one day become humanity's home. The Earth might not remain habitable forever. It could get engulfed by a massive solar flare, or become too hot due to climate change, or have all its life wiped out by one enormous asteroid. What if I told you we could outlive all these disasters? And that we could do that by building a space megastructure bigger than the Sun itself? Just how big would we have to make it? And what would life be like on a structure like that?
