with enough technological progress, it's conceivable we can recreate the past in full HD quality in both sound and vision using the current state of atoms. It would take enough processing power to recreate the universe itself as a simulation, but it's technically feasible.
- Sunspark 4y agoHow is it technically feasible if you need to fit the power to run a universe inside a universe?
- smackeyacky 4y agoProbably need an actual physicist to answer this one, but if the current universe was poofed into existence by a quantum fluctuation, likely you could create your own quantum fluctuation with the right tools and run your simulation inside that. I guess it's science fiction (how would you look inside it? How would you ensure you were re-running your own universe?). Plus there are a pile of moral objections you could make to trying something like that, but it's a fascinating idea that "the problem of evil" isn't created out of malice, but merely curiosity.

- usrn 4y agoThis sounds like the same mistake that people make when they argue for analog computers. Materials have noise so that limits the resolution of analogue data and the Planck constant limits how small things can get regardless. Information is constantly sinking through the noise floor and that's just part of reality.
- nonameiguess 4y agoMuch like the parent is the plot of an X-Files episode, this is the plot of Devs. They just kind of handwaved away the resolution issue with some nod to many worlds interpretation. Of course, as they noted in the show, the ability to reconstruct the past this way implies you can also predict the future using the same technique.
