Some people think that maybe it's just because their life cycle is too long that humans haven't figured it out yet. After all, it has been at least 3.5 billion years since the birth of life on earth. If there are some immortal species, the number will be very large, and it is impossible not to record them in ancient books.
Then, it is called "once and for all" after death. Simply put, since death is irreversible, when life comes to an end, it means a complete end. However, according to some research by scientists, the answer seems not to be so.
Is it true that people are unconscious after death
Let's take a look first. Under what circumstances, it can be judged that a person has died. In some film and television works, you can often see such pictures. If you put your finger on your nostril and find that you have stopped breathing, it means that you are dead.
But from a rigorous point of view, the average person is in a state of "suspended animation" and has the opportunity to be rescued. According to the data, the current criteria for judging whether a person is dead are mainly divided into "cardiogenic death" and "brain death". What is "heart death"? Simply put, people's blood circulation, pulse, etc. Everything stopped and breathing stopped, which was the first stage of human death.
Because man is a complete organic life, when death comes, all organs don't stop working at once. Compared with "heart death", "brain death" belongs to the second half of death.
What is "brain death"? Simply put, it is the irreversible loss and stop of brain function, which cannot be recovered even after rescue. For example, the experimental EEG is flat, which means that a person is really dead.
Generally speaking, there is a time difference from "cardiogenic death" to "brain death", and in the study, scientists also found that people are still conscious when they are dying or just "cardiogenic death".
For example, in foreign countries, researchers have investigated some patients who have experienced "cardiogenic death". These respondents also said that although they entered a state of near death, they did not completely lose consciousness. On the contrary, at this stage, it seems to be the most sober moment in their lives.
What does this mean? The researchers said that these survivors who had experienced a near-death state said that they could hear the cries of relatives and friends around them when they were in a state of "death", and some even said that they saw the picture of doctors saving themselves. However, because they are in a state of "consciousness" at this time, they cannot communicate with the outside world.
What is a "near-death" state?
Simply put, the dying state is the dying state. Compared with the "near-death state", patients in the near-death state have a chance to revive. However, if they are in a state of death, it means complete death and there is no possibility of resurrection.
What kind of patient will enter a state of near death? Generally speaking, it refers to some patients with serious injuries or worsening conditions. At this point, after treatment, their physical functions did not improve, and then they began to fall into a coma. All the signs of the body seem to mean that you are about to die. This process is also similar to the state of "cardiogenic death" mentioned above.
Many people who have experienced near-death state say that they will feel lighter after falling into a state of "mental death", and then consciousness will leave their physical body, just like "soul out-of-body experience".
Then, it will float in the air and fly forward, and I don't know where I am going. However, it seems that my "soul" is based on a sense of direction and destination. After flying for a while, it will enter a black hole, and then continue to fly forward until it finally sees a beam of light.
After that, they will reach the hole. Some people say that they seem to have reached the "world after death" because they actually saw many of their relatives there. However, when they wanted to stay, they were suddenly pulled back by the real world. Of course, this also means that they are "resurrected".
Because many people who have experienced the "near-death state" have described similar conscious experiences in unison, this also makes scientists curious, where is the "other world" where the conscious body goes?
Some people think that maybe human consciousness itself is a quantum structure. When the body dies, it will leave the body and enter the universe. Of course, it is also possible to enter a parallel universe. After all, consciousness is free to come and go, not bound by time and space.
However, there is also a problem here. Since all these dying people have experienced conscious leaving the body, does that mean that "souls" also exist?
It is still difficult for scientists to answer this question. Although in the past 100 years, scientists have done a lot of experiments to find out whether there is a "soul", unfortunately, no experiment can directly prove the existence of "soul", and of course, no related experiment can deny its existence.
So with the development of human beings in the future, will human beings have the opportunity to gain eternal life? At present, scientists have found several ways to make human beings immortal, such as the extension of telomerase and the "smart chip" technology that many scientists are optimistic about today.
However, it is still very difficult to achieve. After all, we mentioned at the beginning of the article that everything in nature has its own law of development. Once mankind breaks this balance, it is very likely to usher in disaster. what do you think?
