Now that Kurt Vonnegut and Robert Anton Wilson aren't around any more, we need another transcendence on paper to remind us it can still be done. My bro' would go for it as well; he got through 'Infinite Jest' twice. Thanks for kicking me in the gray matter.<BR/> I should let Petey talk for himself but he has said now and again that thanks to what he's seen in Hugh Everett, PhD.'s many-worlds interp of quantum theory, there might be possible sub-paths within an established path for any cohesive sentient unit of matter to effect a certain number of changes in a time-travel situation and still end up back where s/he began. Assuming that's what he wanted. So much for Ray Bradbury's 'Sound of Thunder.' In fact, maybe there's a minimum number of fluctuations in any given path that must remain unchanged for the sentient unit<BR/>to do as described above.<BR/>Makes me wonder if possibly Ouspensky's short story and the above view of quantum mechanics are not just dissimilar ways of saying almost the same thing.Francishttps://www.blogger.com/profile/14758803783758905776noreply@blogger.comtag:blogger.com,1999:blog-11168555.post-1146105786133302512006-04-26T22:43:00.000-04:002006-04-26T22:43:00.000-04:00Ben: Current meta-physics (as distinguished from ...Ben: Current meta-physics (as distinguished from metaphysics--but see the late David Lewis' *Plurality of Worlds* for his take on ontological realism regarding modal-logic "possible worlds"...) would seem to suggest that there are many (if I'm not mistaken, at least 5) different senses or aspects of Multiversality. Tegmark, Andrei Linde, Smolin, Dave Deutsch, Saul-Paul Sirag (in his own way) and many others would, if I'm not mistaken, posit an ontology that entails that "time travel" is travel (or access) to an alternate spacetime, or even hyperspacetime. That is, it is literally travel to a (in many ways similar or identical) different spacetime in which event x either fails to occur, or occurs differently, etc. Deutsch & Tegmark, again if my reading of them isn't mistaken [can't guarantee this though!] seem to imply that physically-ontologically possible worlds are indeed pretty much isomorphic--or a better way to put would be *co-extensive*--with modal-logic's possible worlds (again, cf. Lewis, above). Now such different possible worlds may or may not be accessible by us technolgoically (yet), but they may, at least in-principle, be accessible (indeed, traverseable) by/with technology that we can't yet fully (or even partially?) conceive. My intuition (for whatever it's worth...) is that such trans-world access and travel is indeed in-principle quite doable, and that it's only a matter of time (!!!!) before we or our cognitive-intellectual descendents figure out the nuts-&-bolts how-to of it all. Both Saul-Paul Sirag and Jack Sarfatti, e.g., posit the possibility of full-fledged hyperspatial engineering. Which means we (or our descendents) would take-on more-or-less "Q"-like powers/abilities.

Perhaps the magician is only sending back particular parts of Osokin's mind which can conveniently form some basic memories but have no ability to alter behaviour (somehow...).<BR/><BR/>The article, on the other hand, seems to be talking about classical time travel where whole bodies, brains, and minds cease to exist at some time and suddenly appear some time earlier. In this case, I can't see how you can get around the fact that there is a fully functional human being suddenly appearing in the past, with lots of uncanny knowledge of the future (assuming that this strange new time travel technology isn't violently destructive to the human form, of course).<BR/><BR/>What I'm getting at is that regardless of whatever notions of free will we bring into the picture, a fully functional human body and brain will act using the same heuristics and cortical algorithms (or whatever) that it does when it departs in the future. If I go back in time before I was born with the intention of killing my parents, then when I arrive in the past with an identical body and brain I will still have those intentions.<BR/><BR/>Whatever "free will" is, it is *not* some Cartesian Theatre-goer removed from reality which must *act on* reality to get reality to do stuff. If we say "there's no free will" then we are still left with this body and mind which act in particular ways when presented with particular stimuli. If, instead of a human, we sent a simple robot back in time to kill my parents, it would be a little easier to see how powerful physical-law-bending trickery would be required to assure the prevention of the slaughter.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-11168555.post-1119191851132706912005-06-19T10:37:00.000-04:002005-06-19T10:37:00.000-04:00There's a completely separate way of deriving non-...There's a completely separate way of deriving non-paradoxical time travel if we consider time travel as equivalent to travel to other possible Tegmark universes isomorphic to our past (I'm referencing Julian Barbour's ideas of Platonia, with each Now being like a snapshot). I once wrote a long, humorous e-mail to my friend Michael in which I explained this (it's lost, but I'll briefly paraphrase:)<BR/><BR/>Say you go back in time and kill your grandfather. Do you disappear? No: there you stand, covered in his blood, with the memory of having killed him. Now let's say you go back to the present. You now exist in the present, with the memory of having killed him. The copy of you that left in the time machine is not there, having left.<BR/>But suppose you met your exact quantum copy: would you both explode or something? Why would that happen? My reply is that you stop being exact copies almost instantly. Facing each other, they see different views of the room, breathe different atoms of air, and so on. As time passes, they must pile up slightly different experiences, as though they were very, very identical twins, but nothing more. Their memories may match, but only up to the point of their meeting.<BR/><BR/>Suppose, having just returned from killing Gramps, you travel back in time and kill yourself before you can kill Gramps? Then there you are, covered in Gramps' blood, standing over your own dead body, and Gramps is wondering what the hell is going on.<BR/>So you decide to go back to the present and have a stiff drink. With shaking hands you strip off your bloodsoaked shirt and try to mix a martini, but then you come bursting in the door with a flame thrower. This would never have happened if you'd left time/Tegmark travel alone, you poor sod.<BR/><BR/>The catch is that travel in Platonia is different from time travel as we usually understand it; instead of linear travel along the single path we believe to have led us here, in Platonia we would need essentially infinite knowledge about where we are trying to go, which suspiciously resembles the infinite energy needed to exceed light speed (i.e. tachyonic travel to the past). And you need a comparable amount of data on the place you started to get back! Also, if we do live in Platona, there are many possible pasts which will derive our present Now arrangement of matter/energy, just as there are many possible futures deriving from it (this is why I have previously used a chessboard as a metaphor for the arrangement of particles in a Tegmark universe: one would need to know the positions and types of particles/pieces, but also the rules governing their movement).<BR/><BR/>Am I mistaken, or is there a great divide between physicists who calculate what happens if there is one universe and those who assume many?<BR/>If we posit many universes, the backwards-traveling waves are probabilistically constrained from manifesting in their own past timeline, but in Platonia there are many other timelines for them to manifest in. Perhaps this means that we WILL invent time travel, but the paradoxical past effects are prevented in this timeline. And perhaps such travel is inherently one-way.Anonymousnoreply@blogger.com
