Is there life after death? Science offers these hypotheses

Human beings and living things in general are subject to a continuous cycle of life and death. We are born, we grow, we reproduce and we die. Our existence is, in principle, a little ephemeral. But is this really the case?

Many religious beliefs and philosophies propose that death does not exist as a disappearance from the organism, but that we reincarnate or that part of us (whether soul or consciousness) transcends or reincarnates.

What does science think? Is there life after death? In this article, we will explore the different hypotheses established by science.

    The concept of death

    In general, in Western culture and from a scientific point of view, death is understood as the end of life. The body is no longer able to perform its basic functions, losing its homeostasis or state of equilibrium and the heart stops beating and pumping bloodWe stop breathing and the brain stops functioning and recording electrical activity. In this sense, it should be kept in mind that the real death is considered to be the brain, that is to say the one which causes the cessation of the activity of the brain, because other functions can be taken over artificially. . But this death is not a sudden moment, but a more or less prolonged process in which the body comes out.

    That dying means that our body stops functioning as before, is something that most traditions, beliefs and scientific studies share. However, this is where the debate begins. Our body stopped functioning and we finally died. What does it mean? Is there no turning back? Something Happens Later?

      Scientific hypotheses about life after death

      Before we start to comment and debate whether or not there is life after death, it should be borne in mind that while it may seem universal, death can be seen from different angles. For example, in the event that life existed after it, it would cease to be a definitive and finalist thing to become a kind of threshold towards the next phase of existence. Otherwise, we would be talking about the end of being, the existence and the gradual decomposition of what we once were.

      With that said, let’s take a look at some of the various argument-based hypotheses and theories (although in many cases they are considered pseudo-scientific or biased by the scientific community) regarding the existence of a possible life after death.

        Near-death experiences: core of theories that assume the existence of an afterlife

        Much of the hypothesis regarding the existence of life after death arises from the study and analysis of near-death experiences: situations in which a subject is clinically dead (including brain function) for a short period of time. of time, but which he eventually faced. managed to revive himself using different techniques. The study conducted by the University of Southampton in this regard, launched in 2008 and the results of which were published in 2014, is particularly well known.

        The study reflected a large number of cases of near-death experiences in patients with cardiac arrest who were clinically dead but were eventually resuscitated. In most of these experiences and having successfully recovered the patient, it seems to be reflected that he maintained a thread of consciousness throughout the process that even allows him to be able to relate what was going on in the room during the time when he was clinically dead. They also refer to the sensations of floating, of seeing from outside the body (and it is from this situation that they usually describe what happened while they were dead), of feeling slowing down time and peace. In some cases, they also signal entering a tunnel of light.

        It should be noted that it is true that the brain can stay alive for a short time after stopping breathing and cardiac activity: our consciousness and perception do not suddenly turn off, which could even make our constants incompatible with the life we ​​still have a few seconds or even a few minutes of consciousness. But studies by the University of Southampton indicate that in many near-death experiences, the brain had no activity during the reporting period and that the descriptions offered by patients were very precise in describing the objects and situations that arose. when he died.

        Another similar experiment was carried out at the Technische Universität in Berlin, with believers and atheists who were resurrected after being clinically dead and the experiences reflect similar patterns to those described above. These types of theories are among the most important and the ones that have received the most support, leading to conclusions in this regard at the UN.

          Biocentrism: quantum hypothesis

          Another scientific hypothesis that studies the possibility of living after death is, according to Robert Lanza, biocentrism, based on quantum physics. In fact, he considers death to be a product of consciousness, an illusion. This theory implies that it is not the universe which forms life but on the contrary, that life generates what we consider to be reality. It is our consciousness that shapes what we see as the world, including death itself. Also space and time.

          To support this theory, the author takes into account the results of double slit experimentsWhat state a particle can behave as both a particle and a wave depending on how it is observed. It also starts from aspects such as visual perception, which can change if the receptors dedicated to it are altered.

          The aforementioned author takes into account the physical theory of the possible existence of multiple universes. Theoretically, our death could be the journey of our consciousness to another dimension or another universe. Life is seen as a continuous thing from which it is not possible to get out.

          Orchestrated Theory of Goal Reduction

          This theory also starts from quantum physics to consider that consciousness is nothing more than quantum information biologically programmed in the microtubules of neurons. After death, this information only returns to the universe. This theory has also been used in an attempt to explain the visions that some people seem to have in near-death experiences.

          Yuri Berland’s equation

          Yuri Berland is a Russian student who created a mathematical equation in which, based on the consideration of life as information and being related to time, it consequently offers a constant. This could indicate, according to this student, that mathematically, it is possible to regard life as a constant thing and that it therefore has no end, although this is a hypothesis that has not yet been published.

          Hypothesis contrary to the existence of life after death

          A large majority of the scientific community thinks that death is the end, with no evidence of anything beyond it. The neuroanatomical substrate that enables consciousness is the brain, This implies that after the cessation of its activity is also stopped working.

          It is also proposed that near-death experiences and the sensations expressed by those who suffer from it are normal and expected as a result of biological alterations produced at death: the storm alterations cause effects very similar to those mentioned, the light or tunnel vision would be associated with narrowing consciousness and a person’s own pupil dilation in their dying moments and capturing details this may be due to the persistence for a few seconds of the functioning of the brain while the organism ceases to function.
