The hypothetical suffers practical impossibility issues. Nothing happens instantaneously.. everything happens with some degree of change over time... but to answer your question, yes, 'my' life would in effect be completely over. The copy's life would have replaced mine.
Suppose you slowly replace your brain small piece by small piece with copies and after a few months all that remains are the copies. What then?
No matter how long the life span, a healthy path exists.
Indeed, statistical anomalies, or things that are statistically remotely possible, become absolutely certain once you take things to infinity. (e.g. say winning the lottery, with infinite attempts, you'll win an infinite number of times)
Stored information is independent of the medium. The meaning assigned to writing in a book is independent of the ink and paper. Information on a computer is independent of the disk or chip used to retain it.
I believe this is so, information is independent of medium, and even all mediums are in their final nature but information.
That is some say that information/concepts//etc are thus independent of all, they're akin to that which is said of mathematical truths, in other words meaning it's in essence indestructible, perpetual, and without beginning or end,this is in their nature. Even if within a construct of information(i.e. universe) it appeared to be destroyed, in reality from an outside perspective, it would not be. Though the fact that this world seems to show information preservation jibes with these ideas.
which essentially means every possible permutation of anything occurring has its own universe (a universe for every superstring state for every possible timeline)
Indeed, I've heard that strings abhor singularities, that is that the big bang, might not be the beginning, that there is no origin. If an information construct has no origin, it jibes with the idea of information being in essence without beginning, timeless or independent of time. Even if an informational construct appears to be with beginning to those within, from an outside perspective it might be a timeless piece of information. Time too is but information.
But furthermore, if we posit that there exists an infinity of universes going back infinitely, then there must exist an infinity of post humans with an infinite scale of ever greater potential. In essence there must be an infinity of celestial class entities, and one whose power must scale towards the limit of infinity without a beginning or end, timeless encompassing all.
The current laws are based on ideas kin to these...
Vedanta has influenced modern science enormously. Schrödinger was a Vedantist, and he claimed to have been inspired by it in his discovery of quantum theory. According to his biographer Walter Moore, there is a clear continuity between Schrödinger’s understanding of Vedānta and his research: "The unity and continuity of Vedanta are reflected in the unity and continuity of wave mechanics. In 1925, the world view of physics was a model of a great machine composed of separable interacting material particles. During the next few years, Schrödinger and Heisenberg and their followers created a universe based on superimposed inseparable waves of probability amplitudes. This new view would be entirely consistent with the Vedantic concept of All in One."
We may be able to persist for trillions of years, but entropy would eventually take its toll on all of our best efforts.
It's my belief that higher posthuman civilizations can actually escape entropy, either by escaping into another universe or by bending the laws sufficiently.
None of the versions that die consciously experience their state of death. Their continuation versions consciously experience a continuation of their lives.
In other words, subjectively one never experiences true death, nor can one truely kill oneself, only the deaths of those around. Others continue to live, but in another world, and never experience death subjectively.
I've thought about that, but as others have said the only problem I see is that there are infinite number of possible divergencies. Thus there'll be an infinite number of different paths taking by an infinite number of continuing existence.(e.g. One of the existences will continue to exist and have both arms, another will lose an arm, or dog or something, and all other possibilities, etc)
I am not aware of any technological possibility of beating heat death infinitely into the future. Are you aware of any? Paradoxically, the thermodynamics that prohibit immortality locally ensure it globally.
Omega point, wormhole escape into another universe, possibility of variable constants of physics through time or space which could allow if true violation of conservation of energy. Also if there is no beginning(as some are postulating with versions of the newest theories), and there is an infinity of other universes, through space-distortion or hyperspace or other FTL we could reach them and keep going, also some of them might even harbor laws that allow violations to occur.
Greene says that paradoxes like this one or killing the original copy of yourself before you time traveled would be impossible. If you have traveled back in time the time machine exists in the future so none of your time traveling copies (you would see the other versions of your former/future self before you time traveled) were able/chose to destroy the time machine. I have no idea how this interacts with MWI QM, but avoiding heat death and time travel discussions probably should have their own threads since this materialism thread is tricky enough already.
A time machine allows for the creation of infinite energy. (that is you had say a 1 unit of energy, you only use half of it, you go back, and now you start with 1.5units, you use only .5units and now you have 2units to start with, ad infinitum.). Of course the matter that you brought back would probably deteriorate(no worries since your body would as all biological bodies change in composition), but you might use the excess energy to prevent decay.
The only way out of it that I can see is for benevolent intelligence (not necessarily supernatural) to eventually take control of the scenario generation process in future profusions of alternative realities so that most life scenarios in any given universe are "good". That is the optimistic view taken by Tipler, Perry, et al. I hope they are right.
I believe that an entity of such a kind which in a timeless multiverse will have always been, is beyond mere good and evil, it's beyond description.
