Where people sleep and wake up in the future


Cryogenically frozen dead people are being held at a clinic in Scottsdale, Arizona, in the hope that perhaps one day science will be advanced enough to bring them back to life. This unique cryonics clinic is run by Alcor Life Extension Foundationand surprisingly, many people, including some celebrities such as PayPal co-founder Peter Tale, actually spend hundreds of thousands of dollars to keep their bodies here after death.

The idea of ​​waking up in the future sounds like a great plot for a science fiction movie or novel, but through cryonics, organizations like Alcor are trying to do the same in reality. Max Moore, a futurist and former CEO of Alcor, believes that people can be saved from death. “Our opinion is that when we call someone dead, it’s a bit of a random line. In fact, they need rescue. ” he said in an interview. What is perhaps more surprising is that Alcor is not the only cryonics clinic that stores dead bodies for future revival.

What is cryonics and how is a dead body preserved forever?

It’s cryonics on low-temperature preservation of a freshly dead body or severed head of an individual. By comparison, freezing a dead body is called cryonics, and the science of ultra-low temperatures is called cryogenics. In cryonics, the body is stored at temperatures below -130 degrees Celsius in the hope that some advanced technology or nanotechnology will be able to resurrect man. in the future. To protect body parts from any damage during freezing and storage, cryonics practitioners use cryoprotectants and cryopreservation, which can be considered similar techniques to those used to protect the organs of a donor organ from decay after death. .

For those who have signed up for cryonics, the emergency cryonics team takes control of the body after they are pronounced dead for medical reasons. Within hours of death, they wrap the body in ice and ensures that oxygen and blood delivery to the brain. The team injects heparin into your body so that your blood does not coagulate as it is transported to a cryonics facility from the site of death.

In the cryonics facility, the body is placed on a machine that circulates blood and maintains oxygenation, similar to a heart-lung machine. Vitrification solution is introduced. It is a cryoprotectant and works as an antifreeze to protect body tissues from turning into ice crystals during freezing. This is necessary because when your body is frozen, ice crystals can tear cells and cause damage to tissues and organs.

The body is then slowly cooled to about -320 ℉ (-195 ° C) using a liquid nitrogen chamber; once it is cold enough, the body is transferred to a tank of liquid nitrogen where it will be stored at about -320.8 ℉ (-196 ° C) in the inverted position. The goal here is to prevent possible brain damage, even if there is a leak. While the body is stored in containers with liquid nitrogen, cryonists claim that the cells are trusted to remain dormant.

Can cryonics really make people immortal?

although famous people As Paris Hilton, Peter Teale, Steve Aoki, Robert Miller and many others are reportedly looking forward to their bodies being cryopreserved, this is a controversial topic among the scientific community. People who advocate cryonics see technology as a way to overcome death, but on the other hand, there are scientists who claim that cryonics is nothing but pseudoscience that gives people false hope in the name of technology.

According to Max Moore, Alcor is not hope. “Scientific evidence was nothing more than a precondition than a hope for faith in the afterlife. For members … that’s enough to pay. ” Said Moore NBC News.

Denis Kowalski, president of the Cryogenic Institute in Michigan, believes cryonics may sound like science fiction, but in the end it is an optimistic technology. In favor of cryonics, he says“You have nothing to lose, everything to gain, except a little money for life insurance, and for me it’s worth it.” Kowalski himself, his wife and children also signed up for cryopreservation after their deaths.

The different perspectives that cryopreservation researchers and experts have on cryonics may be understood by looking at a lawsuit that has emerged in the United Kingdom.

In November 2016, a 14-year-old girl from the United Kingdom named JS died of a rare form of cancer. Before she died, she leave a note she says her last wish is for her body to be cryopreserved so that she can be revived in the future. In part, the note read, “I don’t want to be buried underground. I want to live and live longer and I think that in the future they can find a cure for my cancer and wake me up. I want to have this chance. That’s my wish.”

JS’s mother wanted to fulfill her daughter’s last wish, but her estranged father resisted. Ultimately, JS’s latest desire not only led to a legal dispute between her parents, but also divided the scientific community in the United Kingdom over the speculative nature of cryonics.

In response to the case, cryobiologist Ramon Risco he said The guardian that while cryonics is now an incredible concept, just as it was once “test tube babies” or space travel, this should not be considered impossible. He believes that in five to 10 years, experts will probably be advanced enough to revive small mammals after canning in liquid nitrogen. “It’s very risky to say that something is impossible in science or technology in the 21st century – people who use the word impossible are very brave,” he said. “If you are looking for the truth, why would you raise barriers?”

Risko also claims that many scientists are against cryonics because supporting this idea could jeopardize their careers. He said: “There is a huge ‘stigma of bias’ in the cryonics conversation among scientists. For scientists who would like to discuss it openly, this tends to significantly damage their careers – in fact, it could potentially even drive them out of their scientific societies.

Clive Cohen, a leading professor of neurology at King’s College, London, was one of those who opposed the Supreme Court’s decision to allow JS’s cryopreservation. Professor Cohen states: “It is ethically very complicated. The compromise is that she received consolation, but others could be deceived. “He even asked in full ban on cryonics marketing.

Renowned cosmologist Martin Rees has also expressed concerns about the practicality and ethical issues surrounding cryonics. He suggested that cryonics enthusiasts could not be trusted because the claims they made were ridiculous. Even a lot of supporters and cryonics experts also acknowledge that there is a chance that some companies will take advantage of people’s vulnerability in the name of cryopreservation.

So far, there is no scientific evidence that fully endorses or explains the possibility of new life in the future through cryonics. When it comes to legal issues, US law does not treat cryopreservation and organ donation as two different things. According to the Uniform Anatomical Gifts Act (UAGA), practices such as cryonics are similar of a scientific experiment for which people voluntarily donate their bodies and organs.

This also means that organizations such as the Alcor Life Extension Foundation and the Cryonics Institute cannot be held accountable if they are unable to revive clients in the future after being subjected to cryopreservation.

Some interesting facts about cryonics

Instead of being buried or cremated after death, thousands of people from different parts of the globe have registered for cryopreservation. However, this is not the only surprising fact related to cryonics.

On January 12, 1967, American psychologist Dr. James Bedford underwent cryopreservation shortly after his death. He was the first person in the world that decided to do it, and his frozen body still rests at the Alcor Life Extension Foundation in Arizona.

Anyone can cryopreserve their entire body at Alcor for $ 200,000 or just the head for $ 80,000. Surprisingly, the Cryonics Institute only charges $ 28,000 to cryopreserve the human body. Asked about this huge price difference, an Alcor representative revealed that a much of their fee is spent to support their trust fund for patient care, which finances the maintenance of the facilities until the moment when the revival is possible.

American baseball player Ted Williams was also cryopreserved in Alcor. The idea of ​​cryonics is quite popular among celebrities; for example DJ Steve Aoki has more I signed up for cryonics but also approved by Alcor.

The number of carcasses stored in Alcor is growing by about 8% per year. The oldest body stored is that of a 101-year-old woman, and the youngest is only 2. One in four Alcor customers lives in the San Francisco Bay Area.

KrioRus, a cryonics company in Russia, also allows its customers cryopreserve their pets. Recently, the founder of Krio Rus Danila Medvedev accused his ex-wife Valeria Udalova of breaking into the company’s cryon storage and theft of liquid nitrogen containers containing frozen dead bodies.

Cryonics is a controversial topic. There is a possibility that, apart from the frozen dead bodies, no one will ever be able to witness their revival or perhaps never return to life.
