Something that is beyond our ken right now. Just as transmitting images would be beyond the ken of a caveman.
Ok, I don't know much about how scientist's hypothesis on how and when the universe will come to an end, but I guess it is possible that tech could be developed to counter certain things.
But, if all else fails, we can travel to another dimension, or even become another dimension, some kind of formless entity beyond our ken. Information is not always matter, information takes the form of energy as well, it's just that in this physical form, we need the energy to materialise in physical form to understand it, whether through visuals, like a computer screen, or sounds, like through a radio speaker.
and as for the other guys who are piling on me, you know damn well I was making a joke about the monks, as soon as you pulled out the phrase 'isolated monks', you knew I'd make a gag about that, because with the stuff you are saying about no-one being able to handle immortality, as the mind and soul needs rebooted etc, I'm surprised that you even brought up the phrase 'isolated monks', because you obviously don't think they would be any different in handling it either, so you were obviously not being that serious when when you brought them up, right? So why not make a joke out of it, which i thought I was obviously doing, which you all know anyway, so please save your high and mighty monk defences for the monk rallys next time they are in town for a Beastie Boys concert.
and as for the whole soul/mind needing rebooting, of course, that's why life is as it is right? So, anyone having immortality would be a new form of life essentially, they would have some sort of new way of rebooting so they did not burn out in that way. What that would be, I dunno, but just as mortal life has the constraints of sleep and death for such purposes, so immortality would have it's ways of keeping the person sane and fresh.
