X-Message-Number: 16302 From: "George Smith" <> References: <> Subject: Time travel and cryonics Date: Sat, 19 May 2001 13:19:29 -0700 Warning: The Surgeon General of Memes has determined that the following may be viewed as off topic if not read to completion. I read the article on time travel from the link on Cryonet and was amused to note that whereas I had been privately informed by a well meaning Cryonet subscriber that the reported capability of actually slowing or stopping the speed of light was not actually what was going on, other scientists seem to think it is. Which just goes to show you that it isn't really necessary to obtain advanced degrees in a hard science field to be ignorant OR sometimes even those of us who are experts in our fields need to remember that what we hold to be absolute bedrock truth today may just be shown to be in error tomorrow. Entropy be damned! History marches on! (1) In any case arguments about why time travel "can't" happen due to our current beliefs about reality (modern physics theory) will matter not a whit if someone DOES it. Doesn't this sound similar to the arguments against cryonics we sometimes hear and read? (2) I think it is absolutely fascinating that an approach to testing the feasibility of time travel has moved from (1950s) "Balderdash!" to (1980s) "maybe rotating black holes with space travel" to (1990s) "maybe neutron stars which are formed into gargantuan rotating cylinders" to (2001) "looped light moving at slow speed". Doesn't this sound similar to the progression of ideas regarding the evolution of cryonics "testing", i.e.: (1960s) "some unknown form of future technology might enable repair of frozen bodies" to (1986) "molecular nanotechnology could repair frozen bodies" to (1990s to present) "possible suspended animation technologies being tested"? (3) Impact to the human world perspective. Any of the following would completely turn on its head our current world view: successful time travel, successful cryonics or simply widespread defeat of aging (such that "old" people grow "young" and "aging" is cured and gone just as with smallpox, polio, etc.). I recognize that taking any of these ideas seriously can be a challenge to the "comfort zone" of most people's coping with future shock (thank you, Alvin Toffler!) but I find them fascinating enticements to a future which will undoubedtly be MORE different than any of use can even imagine.
