Any and all mummies are infotheoretically dead as no neurosynaptic preservation was achieved, whereas electron microscopy taken from the biopsy of a human brain vitrified (not frozen) under ideal conditions immediately after clinical death and placed in intermediate temperature storage shows preservation of fine cellular detail, as shown and explained in the video above. So, yes, cryonauts certainly are the exact opposite of mummies.
only if your definition of mummies doesn't apply to all preserved bodies, including PFA fixation, which in my definition is absolutely a form of mummification, and clearly not the opposite. what is the opposite of a preserved body if not an unpreserved body? :D

Perhaps, but unlike all other types of mummies, cryonauts or "cryomummies" might be restored to life one day.

The truth about cryonics is that what you've got are a bunch of corpses that have been treated in a variety of ways that induce massive cellular and organ damage over and above the original causes of death, dead bodies stored without the means, plan or any practical reason for anyone to ever try to rebuild one of them. They'll all eventually be disposed of in some fashion. Some already have been.

The whole enterprise combines fraud, delusion and egocentric fear in a nearly perfect storm of waste.

I already addressed your ignorant libel earlier in this very thread.

You understand absolutely nothing whatsoever about the philosophical, technical, nor financial aspects of biostasis.

To reiterate, like many stasists, I do not fear death and fully understand that my reanimation is not guaranteed and that even if I am reanimated, I will still inevitably die even then. I don't believe death can be avoided, only indefinitely postponed—a view supported by physics, very much unlike truly eternal afterlife in some immaterial plane or through reincarnation, yet you defend rather than attack such claims.

There's nothing egocentric about people such as Kim Suozzi wanting to take a longshot at having more than 23 years of life, an anonymous British girl taking a shot at having more than fourteen years, the parents of Luna Wilson trying to give their daughter more than fifteen years, or the parents of Matheryn Naovaratpong hoping for more than two years with their daughter. There's also nothing egocentric about a community donating to help those who couldn't afford it enter cryostasis, as was done for Bill O'Rights, Kim, Aaron Winborn, and L. Stephen Coles, nor in sons and daughters preserving their mothers and fathers.

And no, there's nothing wrong with trying to live beyond a century, either. Why should a genetic lottery allow only an extreme few to live in good health into their second century of life? Eventually, healthspans and lifespans far in excess of Jeanne Calment's 122 years will be available to all, and since aging is the leading risk factor for myriad diseases (including dementia, cancer, heart disease, osteoporosis, and sarcopenia, to name but a few), this will lead to an unprecedented reduction in human suffering along with an unprecedented increase in productivity. Aging is not physically inevitable, and as humanity becomes planetary, stellar, interstellar, galactic, and intergalactic, we will inevitably transcend the limitations of natural selection—and biostasis will enable subjectively instantaneous interstellar travel with vastly reduced resource consumption.

Again, vitrification enables far better preservation than freezing, and a vitrified rabbit kidney and multiple vitrified rat kidneys have been restored to function (the rabbit kidney with some damage, and the rat kidneys with no damage) and successfully transplanted. Intermediate temperature storage can already further reduce damage, and the combination of vitrification and intermediate temperature storage in the cryopreservation of the biogerontologist L. Stephen Coles (a cryoskeptic who agreed to be cryopreserved, for free, in order to contribute to science and because he understood that he had nothing to lose) enabled the prevention of both ice crystal formation and fracturing in his brain, as explained by Greg Fahy, one of the world's leading cryobiologists who led the development of the M22 cryoprotectant validated in the aforementioned mainstream kidney vitrification experiments and used in Alcor patients.

Considering what's possible today (including the reanimation of vitrified animal kidneys and of humans without brain damage after two hours at near freezing with no blood in the body), reanimation of people currently in biostasis via technology centuries more advanced cannot be ruled out entirely, and that is, of course, the entire point of biostasis: to attempt to preserve people sufficiently for technology to advance by centuries and possibly enable their reanimation, so attacking biostasis for relying on technology not yet developed is to miss the point altogether.

As several scientific minds (including Isaac Asimov, Arthur C. Clarke, and Stephen Wolfram) who were not involved in biostasis have said, human biostasis will inevitably reach a point at which it is reversible. Nothing in the laws of physics prevents humans from being cryogenically suspended and reanimated, and this is a fact, not an opinion. Whether anyone currently in cryostasis is sufficiently preserved for eventual reanimation is unknown, and since it is unknown, we preserve people as best as possible in the present because we'd prefer to discover that we began to preserve people too early than too late. Reversible human biostasis, though, is certainly a question of when, not if.

Regarding the financial aspects, biostasis is and always has been a nonprofit endeavour, which it must be, since there's no money to be made in it. Only those who truly believe in the possibility of reanimation would bother to keep people in liquid nitrogen indefinitely, with the first cryonaut having been kept in LN2 for over half a century now. Scammers would engineer "mishaps" and reform under a new name, or just blow all the money and collapse.

Here are the financial statements of the three major providers: Alcor, the Cryonics Institute, and Tomorrow Biostasis. All spending is a matter of public record. No one is using biostasis to live lives of luxury. In fact, the founders of all three spent significant amounts of their own money on establishing and building these nonprofit organizations which have charitable trusts to ensure indefinite maintenance of cryotransport even across centuries.

Also, Alcor founder Fred Chamberlain III is now in cryostasis with his father, and his wife and cofounder Linda plans to join them, as does their son, Fred IV. Cryonics Institute founder Robert Ettinger is now in cryostasis with his first and second wives. Tomorrow founder Emil Kendziorra, a physician and entrepreneur, sold two companies before founding Tomorrow despite knowing that it would cost him rather than make him money because he genuinely believes in the cause.

There's even a very small provider, Oregon Brain Preservation, which offers basic cryopreservation (without standby, stabilization, and transport) for $5,000, and another very small provider, Cryonics Germany, which offers basic cryopreservation (again, without SST) for free. Clearly, they aren't in it for money.

RationalWiki mocks biostasis, but even they admit that "cryonicists are almost all sincere and exceedingly smart people. However, they are also absolute fanatics and believe that freezing your freshly-dead body is the best hope of evading permanent death and that the $30–200,000 this costs is an obviously sensible investment in the distant future. There is little, if any, deliberate fraud going on."

Lastly, there's little "waste" since liquid nitrogen costs as little as a dime a liter and each cryonaut costs only a few thousand dollars a year.

Why don't you attack those who believe in attaining immortality through belief in ancient mythology? Why don't you call them fraudulent, delusional, and egocentric? Why does ancient mythology whose practitioners make empty promises (often while raking in millions or billions) deserve respect but experimental medicine whose practitioners acknowledge its considerable uncertainty and make no false guarantees deserves scorn in your mind?

Also, no, Serveaux, I did not misuse "tragedy" and I did not misuse "objective," either, nor did I "project" as you condescendingly claimed in the image thread when I joked about the objective (yes, objective) reality that Yahweh is as fictional as Zeus.

You're an endless stream of patent falsehoods, petty insults, and apologism for ancient superstitions.

Maybe a little pessimistic but with how things are with climate change and the geopolitical situation in the world there might be an actual chance that humanity will have offed itself/bombed itself back into the stone age before finding cures or being able to maintain equipment or the ability to resurrect anyone, I assume no one has a plan B for such an event?

No one has any plan worthy of the name, period. These are pie-in-the-sky enterprises pandering to human vanity.

The dead who have been frozen have no rights under law whatever in most places, of course, and the rights of those assigned as their agents with regard to disposal of their remains are substantially limited in various ways from location to location.

While there's no practical reason to attempt to rebuild a human being from the damaged remains of a dead person - sorry, Mary Shelley - it's conceivable that at some point some of the dead tissues might be used for research purposes of one kind or another. At least then, the expensive farce might serve some useful purpose.

Failure is always a possibility, but once in cryostasis, your prospects can only improve, so there's no risk in trying. It's also not entirely impossible that biostasis could persist through a dark age, since the cryotubes could be refilled as infrequently as a couple times a year due to their extremely high insulation factor, and in the case of chemostasis, room temperature storage is possible, so they could potentially survive abandonment for generations.

Human extinction from climate change or nuclear war isn't possible (someone, somewhere, would survive, even in the worst scenarios) and while the total collapse of human civilization could occur, it's highly unlikely, as explained by Benjamin Todd, founder of 80,000 Hours:


In a scenario worse than the IPCC’s worst case, where all the recoverable fossil fuels are burned, there’s a 1 in 6 chance we’d see greater than 9ºC of warming by 2100. And it looks like there’s an extremely small, but real, chance that this would be enough to cause the worst-case cloud feedback loops.

In total, that would lead to something like 13°C of warming relative to pre-industrial levels. We’d reach that 13°C in the years or decades after we trigger the cloud feedback tipping point — and then there could be additional warming in the centuries and millennia after that. This 13°C of warming would be a humanitarian disaster of unprecedented scale.

As far as we can tell, reaching 13°C is very unlikely, and about as hot as our models suggest it could possibly get on short timescales we might not be able to adapt to.

Now we’ll turn to whether this warming could directly cause human extinction — via pure heat stress, sea level rise, or agricultural collapse.

If temperatures rise high enough, it becomes too hot for humans to survive for more than a few hours — even in the shade. In places with high humidity, like the tropics, it’s harder to cool through sweating, so this effect is even worse.

This could make significant parts of the planet uninhabitable (at least outdoors, or without air conditioning) for significant portions of the year. This map shows the number of days per year we’d get surface temperatures greater than 35°C (95°F) in various regions on Earth, if we had around 7°C of warming. This is a good illustration of the sorts of areas that might become too hot for humans to survive with more than 7°C of warming.

If there were 12°C of warming, a majority of land where humans currently live would be too hot for humans to survive at least a few days a year. An increase of 13°C would make working outdoors impossible for most of the year in the tropics, and around half the year in currently temperate regions.

But even with the cloud feedback loop, it would take decades for global temperatures to reach this level, and while this worst-case scenario would cause extraordinary suffering and death, it seems very likely that we could adapt to avoid extinction (for example, by building better buildings and widespread air conditioning, as well as building more in the cooler areas of the Earth).

Moreover, it would be hard for this to lead directly to extinction even if we didn’t adapt, given that a large chunk of land on Earth would remain habitable, even with 13°C of warming. We would have to live in a much smaller area, but civilisation would survive.​
No one has any plan worthy of the name, period.
You continue to demonstrate your rank ignorance and total unwillingness to engage with any data or arguments presented. Ensuring continuity of cryotransport is, in fact, taken very seriously, which is why ironclad, self-sustaining charitable trusts have been established exclusively in this interest, and preliminary research into how to eventually achieve reanimation is underway.
These are pie-in-the-sky enterprises pandering to human vanity.
It's no more "vain" than any other highly experimental procedure. Terminal patients frequently try unproven treatments with virtually no chance of success because they have nothing to lose, and this can provide valuable data to benefit future patients. Also, cryopreservation costs $0 to $278,000, far less than cancer treatment often does (cancer treatment can even exceed $1,000,000) despite its frequently high failure rates. Where are the accusations of vanity against oncology?
The dead who have been frozen have no rights under law whatever in most places, of course, and the rights of those assigned as their agents with regard to disposal of their remains are substantially limited in various ways from location to location.
Many have been vitrified, not frozen, and the lack of legal rights won't prevent reanimation. We're not asking for permission.
While there's no practical reason to attempt to rebuild a human being from the damaged remains of a dead person - sorry, Mary Shelley - it's conceivable that at some point some of the dead tissues might be used for research purposes of one kind or another. At least then, the expensive farce might serve some useful purpose.
As I've repeatedly explained and you've repeatedly ignored, there are indeed reasons to attempt to reanimate cryonauts, and it is neither expensive (the lowest price is free and the most expensive option is accessible through life insurance) nor a farce (vitrified animal kidneys have been reanimated, people have been reanimated after two hours at near freezing without any blood in their bodies, and electron microscopy of a vitrified human brain suspended in intermediate temperature storage shows no ice crystals or fractures).

As I said, the reanimation of people currently in cryostasis cannot be ruled out altogether, but if even if no one currently in cryostasis can ever be reanimated, reversible human suspended animation doesn't violate any laws of physics and so will inevitably be achieved if we continue to work on it. Since reanimation is much more difficult than preservation, the first viable preservation will occur, if it has not already, long before the first reanimation, and we would prefer to ultimately discover that we began to preserve people too soon than not soon enough. We do the best we can at any given time, and someday, people will be reanimated. Perhaps we'll be able to recover people preserved as far back as 1967, or maybe we'll discover that only the introduction of vitrification in 2000 made reanimation viable. Or, we may discover that technology introduced in, say, 2068 or 2139 is the minimum necessary for viability. We probably won't be able to make a conclusive determination on this for centuries, but we do know that cryopreservation will eventually be able to preserve personal identity and enable recovery one day if it hasn't already. The ability to reliably preserve human organs and whole human beings will be of immense benefit to medicine and space exploration and colonization.

That you defend ancient superstitions which falsely claim to offer certain eternal life and make millions and billions for a parasitic few at the expense of the masses while you attack experimental scientific attempts to extend life which are honest about uncertainty and where the money goes is telling. You are an apologist for superstition and the status quo and an opponent of the inevitable radical improvement of the human condition. It is entirely possible that no one currently in stasis will ever be reanimated, but if humanity advances far enough, we will inevitably transcend this planet and the limits of natural selection.

To think that we'll always or should always be afflicted by disease and senescence and limited to a century or less of life, even after eons of scientific and technological advancement, is as absurd as thinking that we'll never leave Earth.

Nowhere in his posts in this thread did @Serveaux mention faith in a god or support of religion; you're dragging an argument you're having with him in The Neutral Zone out onto the rest of the board, which violates TNZ's fourth rule: "No discussing the events in TNZ outside of TNZ." For that, you get a warning and will be banned from TNZ for 14 days just as soon as an admin can flip the switch. There may be further action from this forum's mod or an administrator, but in the meantime, you can take any comments about this action to PM.

Because it's directly relevant to this discussion: he criticizes biostasis as fraud for trying to extend life supposedly without any evidence yet defends religions which promise eternal life without any evidence whatsoever.

Also, this thread is partly about "The Neutral Zone," ironically!

@Serveaux, thus far, you've repeatedly ignored all the points I've raised. I invite you to engage in debate rather than continue to pontificate.

1) Since biostasis is offered on a nonprofit basis and all finances are a matter of public record, how can biostasis be fraud? Even RationalWiki's snarky article which denounces biostasis as pseudoscience admits that there's no fraud, just earnest belief, even if fatally flawed. The founders of the two oldest providers put a lot of their own money into them and are now in stasis; they clearly weren't motivated by financial gain. Also, two biostasis providers provide their services for free; how can free be fraud?

2) Since I believe that my reanimation is far from guaranteed and that even if I am reanimated, I will still inevitably die at some point, how do I fear death? I see biostasis as a highly experimental, highly uncertain longshot, nothing more.

3) Since even centuries of cryostasis costs less than a year of cancer treatment (due to the extremely low cost of liquid nitrogen and extremely high insulation factors of cryotubes), why is cryostasis egotistical but cancer treatment isn't? What's egotistical about a fourteen-year-old girl or 23-year-old woman taking a longshot at being able to "finish life," as that 23-year-old put it? What's egotistical about parents preserving their children and children preserving their parents? What's egotistical about donating money to help strangers be preserved? What's egotistical about a multimillionaire offering free suspensions to the public instead of buying a yacht?

(Shortly before James Bedford became the first cryonaut in 1967, he declared that he had little hope of reanimation for himself and agreed to enter cryostasis in the hope that his primitive cryopreservation would contribute to the development of cryobiological knowledge for the benefit of future generations. Although the small organization which froze him offered to do so for free, he insisted on covering the cost himself, and donated the rest of his estate to cryobiological research. None of this seems egotistical to me.)

4) What do you understand about human cryopreservation or cryobiology in general? Considering that with current technology we can a) reanimate cryogenically vitrified rat kidneys without damage, b) reanimate people without damage after two hours at near freezing, no neurocardiopulmonary activity, and no blood in their bodies, and c) vitrify human brains with zero ice crystal formation or fracturing, why do you feel certain that their reanimation will never be possible even with the benefit of technology centuries more advanced?

(Greg Fahy, one of the leading minds in mainstream cryobiology, having led the development of the M22 cryoprotectant used in the first reanimation of a vitrified animal kidney, believes there's a nonzero chance that people currently in cryostasis could be reanimated in the distant future. The seventy-eight signatories of the Scientists' Open Letter on Cryonics and various scientists not involved in biostasis agree.)

5) You claim that there are no long-term plans in place, but there have been for decades: the major organizations have established irrevocable charitable trusts which grow continuously by generating interest and not touching the principal, and at least ten million dollars are spent on human biostasis research annually.

6) Why shouldn't all diseases be cured, and since senescence is the leading risk factor for a plethora of diseases and the killer of twice as many people as all other causes of death (natural and unnatural) combined, why shouldn't senescence be cured? Why should a genetic lottery enable a select few to live over 100, 110, or even 120 years while many more die of genetic disorders in their fifties, forties, thirties, twenties, teens, and even earlier? Do you think humans will or should always—even eons from now—age and die within a century or so? Or, could indefinite healthy lifespans be achieved for the benefit of all in some distant future?

7) If we shouldn't reanimate cryonauts because the planet is overpopulated, why should we not limit a wide range of medical treatments? Why not encourage higher mortality rates in the interest of reducing overpopulation (not executing or involuntarily euthanizing people, but simply "rationing" care)?

(Note that global population is projected to decline in the next century, and there's a whole universe out there...)

8) What do you think about developing biostasis for deep space travel?

Since @Victoria, @1001001, @SithHappens, @StarMan, @Jack Wolfe, @Chakoteya, @BillJ, @Nerys Myk, and @NCC-73515 have indicated that they agree with your view, I'm also interested in hearing their perspectives as well as those of any others.

Here, when you called cryonauts "perfect mummies"—but mummies don't have the microscopic structure of their brains preserved, whereas electron microscopy of a human brain cryogenically vitrified under ideal conditions shows individual cells are preserved without ice formation or fracturing.
 
maybe you could clarify how different mummy definitions align with all the TLDR you wrote above :shrug:
"Mummy" implies no scientific possibility of reanimation, does it not?
What's the biggest mammal that has been cryo preserved, any method, and then brought back to life after at least a day?
None yet, primarily because each organ and tissue type requires its own cryoprotectant formulation for maximal preservation quality; the cryoprotectant used to recover rat kidneys without damage isn't suitable for the rest of the rat body, hence the Shandong Yinfeng Life Science Research Institute, which combines mainstream cryobiomedical research with human cryopreservation, has developed over thirty cryoprotectant permutations for various organs and tissues.

Human cryopreservation prioritizes the brain and as of 2014 can bring it below the glass transition temperature of water (at which point all degradation stops) without ice formation or fracturing in the most ideal cases of a suspension team being at the patient's side prior to deanimation (clinical death) and beginning the process within one minute of deanimation, beginning with external reinitiation of cardiopulmonary activity so as to dramatically reduce ischemic damage.

The goal is simply to preserve the information in the brain so that technology which may not exist for centuries (if it ever does) may enable its recovery. We don't expect to be reanimated in the near future and accept that we may never be.

The North American wood frog's own natural universal cryoprotectant points toward the possibility of a universal cryoprotectant for humans as seen in science fiction, but only the brain is truly essential; the rest of the body will be replaceable through future therapeutic cloning or bionics.

Hamsters noncryogenically frozen for up to seventy minutes are the closest so far.

Hamsters which had supercooled to temperatures as low as — 5·5° C revived fully and lived for many weeks or months thereafter. Few animals which had crystallized spontaneously after supercooling to temperatures below — 3·5° C recovered fully and none survived more than a few days thereafter.

A high proportion of hamsters which had frozen progressively for 50 min or less recovered completely and survived indefinitely. Seventeen of the twenty hamsters frozen for between 50 and 70 min recovered and, of these, eight survived long periods.

Animals frozen for longer than 70 min seldom revived fully, although spontaneous breathing was resumed in those frozen for 90 to 159 min and heart beats in those frozen for 160 to 170 min. Autopsies showed that the chief cause of death was haemorrhage in the stomach, intestines, or lungs.

Frostbite and lesions of the eyes were rare, and no changes in behaviour were noticed in fifty-nine animals which were studied for 100 to 450 days after resuscitation.

I wouldn't normally respond to this kind of tagging because it tends to feel to me like someone spoiling for a fight... In this case, I'd been thinking of posting something about practicalities.

1) At the minute, there's no known method of preserving/reviving people except for some very short periods of times. It is possible that, at some future point, a long term method may be developed. However, the people who could be revived by such a method would be the people preserved by that method. So that's going to be the people preserved after that technique is developed who will be revived. Anyone preserved before the method is developed will not be. They will be waste. As no such method exists at present, preserving people is pointless.

2) In any case, what is the point of reviving people who have been in preservation for many years? The world is hardly short of people and has a well-known and well-understood method of natural replacement. Any revivee would find their knowledge and skills to be well out-of-date. They would not understand cultural and social references.They would have no idea of recent history and the way societies have developed Their family and friends would have moved on or died. Language develops and changes all the time - the revivee would be, at best, like someone trying to understand their 14-years-old grandchild talking to their peers: at worst, like someone trying to understand Old English (insert language of choice). Just what is the use of reviving someone in those conditions? They aren't going to be contributing anything useful and are likely to be lonely and isolated. Again, it seems a total waste of time and resources.

Thanks for your reply. I'm interested in understanding people's questions and concerns. I've been fascinated by the idea of cryosleep since my preteen years and it's always made sense to me as a last resort, but I realize that places me in an infinitesimal minority (about one in a million, in fact).

We actually can't and aren't even close to being able to reanimate people from even the briefest duration of cryostasis. The best we can do for people is to bring them back after up to two hours at just above freezing.

However, one second at normal human body temperature is equivalent to over 24 million years in liquid nitrogen. If someone remained in liquid nitrogen for an eon (one billion years), the equivalent of just forty seconds of decay would have occurred (and liquid helium would prevent all degradation for far longer than the current age of the universe, probably until its heat death). On the scale of centuries or even millennia, no degradation occurs.

So, Dr. James Hiram Bedford is in exactly the same condition as when he entered cryostasis in 1967, and as long as he remains in liquid nitrogen, he'd remain in that same condition in 2200, 2500, and beyond. The length of time is actually entirely irrelevant; only the level of preservation at which one enters cryostasis matters.

Therefore, if the initial cryopreservation process preserves the brain sufficiently to prevent information theoretic death—meaning the information it contains isn't truly destroyed—then reanimation would be possible even after millions of years.

Conversely, if someone was insufficiently preserved, then reanimation wouldn't be possible even a minute later even with the most advanced technology physically possible.

Electron microscopy of a neural biopsy taken from a human brain vitrified under ideal conditions (vitrification at intermediate temperature begun immediately after deanimation/clinical death) shows no ice formation as well as no fracturing, strongly indicating that infotheoretic death has not occurred.

Since the price can be as low as free (and even the most expensive options are accessible through life insurance) and it can't make you any more dead, I see no reason not to try. We don't know when the minimum viability threshold was or will be reached, but we do know that it came or will come long before the first reanimation, since preservation is much easier than reanimation. Better to preserve too soon than not soon enough.

Resource consumption is also extremely minimal because condensing and separating nitrogen from air requires very little energy, the nitrogen returns to the air as it slowly boils off, and the cryotubes have extremely high insulation factors.
2) In any case, what is the point of reviving people who have been in preservation for many years?
If we could bring even completely unremarkable people back from centuries in the past, there would certainly be immense public interest in doing so.

Many people have difficulty adapting to sudden change, but not all. The first Aboriginal Australians who encountered Europeans effectively traveled tens of thousands of years through time and managed to adapt.

Immigrants have always adapted to unfamiliar cultures, sometimes without family or friends. Some cryonauts have or will have family members in stasis with them. Most have or will have at least a few friends with them. All plan to make new friends and possibly start new families.

Even nontechnical people in current generations are adapting to new technologies, and those of us who anticipate radical technological advancement would enjoy encountering it.

Adapting to a distant future isn't impossible, and cryotransport providers intend to assist cryonauts in reintegration if necessary.

Also, the same technology which would enable the repair of 86 billion neurons, 85 billion glia, and somewhere from 100 trillion to one quadrillion synapses would also enable the creation of rapid memory and knowledge downloads into the brain, like when Neo absorbs decades of martial arts experiences in minutes in The Matrix or when Quaid "remembers" a fictional life in Total Recall. Such technology could make reintegration seamless.

Automation will surely be much more advanced and waking into a postscarcity society is also a real possibility for the distant future.
