cokadaGetty Images Russian researchers have outlined several ways technological resurrection may be possible in the future, including a method called digital immortality: restoration based on recordings. In this method, a superintelligent AI uses the cosmic Dyson Sphere megastructure to harness computing energy from the sun. Humans can’t build a Dyson Sphere—yet—but the researchers say nanorobots could one day do the job. Imagine this: In the far, far future, long after you’ve died, you’ll eventually come back to life. So will everyone else who ever had a hand in the history of human civilization. But in this scenario, returning from the dead is the relatively normal part. The journey home will be a hell of a lot weirder than the destination.
