He knows the science of death

Zaradi.com.ua_17.08.2016_g8oOSvUeTtTcJDeath will come to love each of us, as if we didn’t fight. Eat only healthy food, Jogging in the morning, give up alcohol, avoid stress, upgrade your body with Cybernetics, kolis antibiotics, swallow vitamins, do it all at once, and after that — welcome to the coffin, don’t forget to close the lid as tightly as possible.

There isn’t a nutty Professor, is able to resurrect you or give you eternal life — such persons live only in books and films level «Reanimator». However, who does not like scientists know about death more? The scientific mind is associated with the problem of death close-knit. Science and death made a kind of marriage after the most devastating epidemic in human history — the medieval plague, popularly referred to as the «black death». After 2/3 of Europe’s population was in the ground (in Italy they buried people in rows and a layer of sand, a layer of bodies, a layer of sand, a layer of corpses, «lasagna»), the scientist folk decided to take his head and, finally, to think about death, its nature, purpose and methods of dealing with it. Since then, a host of «theories of death», backed up by research, logic designs and experiments, but none of them is a leading and well understood. Men of science are still working in this direction, revealing the mystery bit by bit. Their ideas are so unique and interesting that today we decided to take them on the course. We will discuss death, and not from the point of view of philosophy or of society, and from the point of view of science. In this context it is discussed very rarely.

1. Quantum suicide

Let’s start with the biggest ideas based on quantum — toy of modern physics, which means indivisible portion of any quantity (so will have to get into Wikipedia).

Quantum suicide is a thought experiment in quantum mechanics. Invited two of his guy and, as usually happens, they did it independently from each other with a difference in one year: Hans Moravek told about quantum suicide in 1987, and Bruno Marshall told about him in 1988. The experiment can understand and not dedicated.


His conclusion is that every event in space-time causing the Universe to divide itself in different versions contains all the possible results. For example, we advocate multiple interpretations of the Universe, and we are sick in the head scientists who performed the unfortunate experiment, the essence of which is that rifle will shoot with a probability of 50 %. So, in one world, the gun fires — the participant of the experiment dies. In another world the gun misfires and the subjects lives, and so the experiment continues.Regardless of the outcome of events in our world, the party will still survive (not here, in a parallel universe). This means that he will live forever and it is this Guinea pig, is immortal, as we all do.

2. We don’t know what death is

manygoodtips.com_17.08.2016_4UNpB8tZp8eZGWe can’t be 100% sure of death, because we don’t know what life is and what can be called life.

Scientists are trying to get a decent and accurate definition of life, but as it turns out they had it not. Of course, you can get the definition of NASA, which turned on the search for aliens. They say: «Life is a self-sustaining chemical system capable of evolution». But even that is not perfect, as there are such sets are non-living chemical systems that can mimic a life without being alive. Crystals, for example.

There is also the problem of consciousness. People do not know what consciousness is, what caused it and how it survives death. Scientists do not know exactly, destroyed consciousness with brain death, although say: «I guess it dies with the brain.» That is, until we can come up with a comprehensive, solid definitions of life, we will never truly understand death.

3. Three kinds of death

Technically, there are three different stages of death and, moreover, one of the stages is reversible.

It all starts with the clinical death is the cessation of vital functions, heart rate and respiration. Brain activity may persist. People who’ve suffered clinical death, can be called «technically dead».


Comes after biological death, sometimes called brain death. Sometimes biological death stands as opposed to clinical death, as brain activity stops, and the vital functions of the body still can work. From a medical point of view, such a death it is impossible to convert.And finally, there is molecular death, which refers to the stage where the body finally ceases its struggle against decay. Frankly, few would want to at this stage, death was reversible, except that Director George Romero.

4. The fear of death depends on age

There is a widespread belief that the closer to death the more you are afraid of it. Statement, I must say, is very controversial and is refuted by several studies in which it was discovered that older people generally less worried about death than young people.


The fear of death, according to these studies, the most striking in 20 years, then it goes into steady decline, until a midlife crisis (at this time can expect a slight mental shock), after — the adoption of Zen and harmony.At the same time, the study took into account different people at different stages of life, so we can’t be 100% sure that the effect is not caused by differences in generations. Only time will tell that the current generation of twenty years at an alarming rate turns into a generation of anxious pensioners.

5. A death spiral

Work.com.ua_17.08.2016_061UBI0kHjAo0Great title for a black metal band, isn’t it? In General, this term is purely scientific, it represents a stage precedes death, which is part of the process of genetically programmed death. Its essence — the decline of physical activity.

The death spiral was first described in the study of Drosophila (a type of fly), which ceases to lay eggs at the moment of dying. Thus, the «spiral» was not the result of death and its harbinger.

In human body there are indicators of life, which represent daily activities. We eat food daily use the toilet, brush our teeth and stuff. But at the time of the «spiral of death» the frequency of these actions is greatly reduced.

6. Age limit

Over the last century average life expectancy has increased for decades. However, it has more to do with the fact that most people live to old age and the fact that there has been an actual increase in life expectancy. In ancient times we can see a century old — then they are few who could surprise. Despite all our efforts, one of the oldest people of our time a little more than 120 years. Many agree, but the head of such age is not spinning.


It is believed that there is a certain age barrier, through which one can overcome not. This barrier is called the Hayflick limit. Its essence is to limit cell division. Infinitely the cells to divide can not — she has a limit. This limit varies between organisms, with the result that the hamster lives a pretty damn small, compared to a Galapagos tortoise. The reason is that shortened telomeres — stretches of DNA at the ends of chromosomes that protect them from degradation.It seems that at the moment, 120 years is the limit of natural human life. That is, even if we give up other causes of death such as disease, we still come to the line at which people are dying from «old age». However, if we could find some way to solve the problem of cell division, it is possible that we would extend human life indefinitely.
