Every conscious or unconscious person questions the meaning of life in various stages of his life. This questioning naturally forces the individual to think about life after death.
First of all, what is life? Let's try to answer the question.
Since I look at life through the eyes of a physicist, I will not be able to establish very sublime or religious sentences. This preference does not mean that I do not know, but my preference has always been to know and question. Research produces us questionable or verifiable results.
Life gives the whole of the relations of all living things and inanimate within a whole. It is not possible to distinguish one part from the other, as well as to hold one above the other. The existence of each constitutes life and life cycle. For example, there can be no oxygen without trees. Without oxygen, we cannot breathe and we die. Again, there can be no forests and animal communities without trees. We, who do not have a food source, die again. Without seas, there can be no oxygen. Again, the tip touches us. There can be no sea creatures without the seas, and we have problems with food again. As you can see, oxygen, sea, and soil are not in the living class. However, life cannot be possible without them. After all, we arrive at the point I said at first. Living and inanimate are parts of life as a whole. The absence of anyone causes the death of life. So life is a whole. And it's like a nested multidimensional sphere. The reason I chose the sphere here is the most perfect geometric form sphere we know in the universe.
It is actually a very difficult subject to draw only human life from this whole and think about it. Leaving aside the issues beyond physics (spirit, chakra etc.); human physiology is basically an electrical scheme. Let me give an example by reducing it very simply. For example, what do doctors do to relive the deceased patient? They use electroshock therapy at different voltages with electroshock device. Why? Because human is an electrical circuit. It is necessary to give electricity to restart a person whose electricity generation has stopped. There is no doctor who does not know this. Also, if there is no brain function, we are dead again. The brain is an electrical structure that contains hundreds of billions of synapses and neurons. Electric circuits open and close every trillions of times every minute to operate and carry, process and evaluate the necessary data. For example, your eyes are not enough for you to see. It should also be the occipital lobe to process electrical currents from the eyes. The occipital lobe is a lobe located in the lower back of the brain. Without extending the subject of anatomy and going into details, as a summary, without electrical circuits, the human body and brain do not live. The digestive system produces the necessary energy by passing the food taken from the liver through biochemical processes. This energy is electricity.
When a person dies, all electrical circuits are closed. So there are no memories, information, consciousness, muscle mobility, hearing, sight, taste, smell, feeling. These circuits cannot be operated again after a while. Because we live with millions of bacteria in our body. These bacteria begin to quickly consume the dead cells. It is these bacteria that cause the dead creature to produce odor. It is also not possible for the clotted liquid to reach its original composition after the blood has dissociated.
The subject described as spirit or soul is our consciousness and electrical circuits. Spirit = consciousness (it is our ability to know, understand, remember.) Vita is our electrical circuits that give our ability to feel life with all our sensory organs. When this system is shut down; We express that the creature is dead. There is nothing beyond physics that goes anywhere. The structure of the universe works on the laws of physics. Man is a tiny part of the universe and it is impossible to have a different structure from the whole.
But still the idea of eternal life exists in all belief systems. It is strange that we only understand or make sense of our own species from the understanding of eternal life. Of course, as long as the solar system and the world exist, life will continue to be eternal. A creature dies. The bacteria in the soil are fed from that living thing. Bacteria nourish the soil. Plants and trees feed on soil. Animals feed on plants. And this system works in an infinite loop.
However, there is only one detail. The fossils and the rest are usually bones. Bones contain the DNA of the creature. It is very well preserved; For example, a fossil bone frozen in the glacier can remain intact for billions of years. Otherwise, the DNA in the bone of a buried creature has an average half-life of 521 years. This means that it can be used again for about 1 billion years. However, discussions on DNA continue. DNA in a 65-million-year-old dinosaur bone was degradable and readable. Studies are ongoing to separate the DNA of 3.7 billion years old marine fossils. Even if it is science fiction yet; Now I want to talk about the footsteps of a technology that could be possible in the coming centuries.
Separation of DNA from other environmental factors; it allows DNA to be analyzed. Even if there is a possibility; By using the relevant DNA, it will be possible to revive a living thing that died billions of years ago. But this technique is at the very beginning of the road. It also requires many different technologies to be developed along with the reconstruction. This gene biology technology is not yet available. Even what kind of devices will be needed has not been determined yet. We can assume that this technology will be as common as dental tools within an average of 1000 years. What does this mean? It will require the introduction of certain legal restrictions, both ethically and technologically. For example, there is CRISPR, that is, gene software technology today. It is possible to change the genetic structure of a living thing (man). In other words, although it is possible to change eye color, intelligence capacity, possible disease picture, height, skin color, etc., it cannot be used due to some ethical problems and how to overcome ethical problems continues to be discussed.
Similar ethical problems will be in the technique of bringing them back to life. If these ethical problems are overcome; Perhaps the return of allowed creatures to life will be ordinary in the coming centuries. But I think this approach is a perspective that can disrupt the infinite life cycle. The natural system has developed in the direction of the flow of life in different themes and colors instead of hosting such a structure in itself. It is not possible to directly intervene in this issue and predict which existing systems will cause malfunction. Because ecological balance is a structure that operates trillions of parameters in a balanced way.
We can continue thinking from this point.
