Humans have done a lot of research and attempts to "Live forever", but most of the attempts have not really achieved the effect of immortality. After all, the human life span is limited by many factors, such as genetic limitations, such as diet and habits can also affect our physical and mental health. Despite this, many people hope to live forever, and will even take some way beyond our imagination to let themselves "Save". For example, some people will freeze themselves at the time of death, until the future of technology is sufficiently developed, and then thawed, and then use the future of advanced technology to treat.
The first person to freeze: The wealthy bedford
The world's first frozen man was billionaire professor bedford. Bedford was frozen in 1967, and according to the original plan, he was supposed to be thawed in 2017, 50 years later. What has happened to bedford, who was originally scheduled to be awakened five years ago? Let's look at the reason why bedford was frozen and the process of freezing, and we may know the answer.
Bedford, a professor of psychology, was suffering from cancer when he saw dr. Robert ettinger's book "Immortality. After seeing dr. Robert ettinger's book "The prospect of immortality," He thought cryonics might allow him to be "Reborn" In the future. When nielsen, a cryonics expert, made an offer to freeze him, bedford did not hesitate to say yes, and he paid for the freezing chamber and liquid nitrogen used to freeze him, and also made a will.
On january 12, 1967, bedford passed away, and a team of cryonics experts immediately took steps to freeze him. The process of cryopreservation was roughly as follows: Bedford was given an anticoagulant to prevent blood clotting throughout his body, and then a cryoprotectant was used to replace all of bedford's blood. After these operations were completed, bedford was placed in a stainless steel tank filled with liquid nitrogen, leaving the remains immersed in -196°c liquid nitrogen.
The reason why bedford wanted to freeze himself was simple. He was suffering from cancer at that time and could not be treated. He wanted to freeze himself and wait for medical technology to be advanced before he was awakened and his cancer was treated with advanced medical technology. Apparently, in 2017, 50 years later, mankind is still unable to conquer the technology to treat cancer, and there is no technology to revive a body that has been frozen for decades, so bedford's idea fell through.
After all, bedford was dead before freezing. Moreover, the freezing technology at that time was also very primitive, simply replacing the blood with some cryoprotectant and finally putting it in liquid nitrogen for freezing. Such an operation, in fact, simply can not be revived.
People are still conscious after death
What happens to a person after death? Where do they "Go" After death? This is a topic that scientists have debated endlessly. Because a person after death can not tell us about what he experienced at the time of death, so many of you think that the relevant research is not scientific. After all, no one will try to go to the "Ghost" To walk through the door and then come back to us to explain the situation. However, some scientists have learned through some research methods that people are still conscious after death and know they have died.
Some studies in the united states have shown that when a person's heart stops beating, the brain still continues to work for a while, which means that at the time of death a person's brain can still be aware that they are dead and can even hear the doctor announce their death. Human death is an irreversible thing, how do scientists know that people are still conscious at the time of death?
Researchers interviewed a number of patients from europe and the united states who survived cardiac arrest. These patients who survived cardiac arrest told the researchers about some of the things that happened around them after their hearts stopped beating. Some of the patients who experienced near-death experiences may have even seen a long "Tunnel" And saw light again at the end of the "Tunnel. Some survivors have also reported being able to feel as if they were floating in the air, free from their damaged bodies.
Since people are still conscious at the time of death, is there any way we can preserve their consciousness and transplant it into other "Living" Bodies, such as an advanced robot? If we can transplant the consciousness of the deceased to a humanoid robot, does it mean that the deceased survived in another way?
Although scientists did find that people are still conscious at the time of death, but the consciousness does not actually stay for a very long time, and may not have time to react before the consciousness disappears, there may just be some faint consciousness at the moment of death. Such a short period of time, the doctor is actually too late to transfer consciousness to the robot. Moreover, the robots at this stage are not at such a level. Therefore, this one method, at present, can not be achieved. However, in the future, if technology is sufficiently advanced, humans may be "Immortalized" In a way that we cannot imagine at present.
