None of which matters because: You'd need to store it, and our universe is finite, so there isn't enough room. Much worse the universe despite being finite is already so enormous and growing that you cannot cross it, so it would be impossible to actually perform computation as even if the data exists it can't necessarily ever be moved from where it is to the site of computation - it may get further away instead despite travelling as fast as possible.
