Science and philosophy seek to explain what happens to us when we die
The obsession for a life after death has captivated the mind of humanity since his conscience realized the end of his days. For the Vikings, dying in battle meant traveling to Valhalla and taking a place at the big table where other warriors toasted each night with their god Odin, waiting for the time to face the end of time in the battle of Ragnarok. Egyptians, Aztecs and other glorious empires of antiquity made death a crucial part of their cosmogony, art and rituals, so that the deceased faced their journey to the afterlife successfully and their judgment before the gods was positive.
In their attempt to offer convincing answers to the main concern of the human being, the different religions and science are still questioning: what is beyond death? The promises and answers to such an enigmatic question are diverse. At present, theories based on scientific research or on philosophical or metaphysical dissertations have been developed so that this questioning is resolved as soon as possible, which - unfortunately - still seems difficult. There is no right answer, but fascinating explanations about it:
Theory of the multiverse: death is only an illusion
This is how Robert Lanza, a doctor and director of Advanced Cell Technology, thinks that it is conscience that determines life and that we are conditioned by what is mentioned as truth for the construction of mental patterns. For him, the spatio-temporal dimensions are mere constructions of the brain, including death. It also gives credit to the existence of the multiverses, so that not only death does not exist for this scientist, but there are thousands of lives scattered in infinite possibilities.
Solipsism: only one person exists
The adepts to solipsism affirm that there is only one person in the Universe and that she imagines everything that she sees and happens around her. It is very attached to the previous theory, in the sense that it is the mind that makes reality and death through its consciousness. When the person dies, the entire universe ceases to exist, because his conscience created it giving way to another state: that of the space-time universe of the Hereafter. With the birth of another individual, different forms of life would be reborn under their consciousness and their capacity to create other universes with different laws and their own spaces.
Theory of the big brain: you will be expelled sooner or later
This theory states that the Universe is a kind of giant brain and we are part of an infinitesimal part of its structure. Our galaxy would be just a kind of stain or connection of the complex composition of this system. As it happens with the human brain, which often discards unusable elements, our death would be something similar to it: the end of our conscience would mean being expelled from that great brain and end our days in a kind of limbo.
Theory of the Consciousness of the Universe: the return to the origins
According to scientists Sir Roger Penrose and Stuart Hameroff, consciousness comes from quantum activities from within brain cells. That is, approximately 20 watt discharges that allow us to capture reality through our brain and give shape to what scientists call Cosmic Consciousness, which connects all forms of life. Upon dying, the consciousness of human beings would return to that Cosmic Consciousness with the possibility of returning to the world or remaining indefinitely in that great universe.
Déjà Vu theory: life is repeated again and again
Our existence would be like an album that when it reaches its end is repeated again and again. Nobody would be aware of this repetition more than in the déjà vu that are sometimes experienced and that would be as a reminder that life is a cycle that has been occurring for tens or hundreds or thousands of years without being disturbed except in small details. In reality there would be no death; the Hereafter would be life itself with its different versions of itself.
Sleep theory: all you see is the imagination of your inanimate body
Yes, maybe at this moment you are in a state of animated suspension reclining on a hospital stretcher, a spaceship or a place you can not even imagine. Everything you are doing at this moment, in what you call "reality", is a dream and death would be the awakening to your true consciousness. Maybe your true appearance, the people around you or the world you live in is not the one of your dreams. The same theory points out that perhaps it is possible that each of us is the dream of a higher consciousness that dreams us so clearly that it has been able to create our lives.
It can be frustrating that you still do not know what actually happens when life ends and the body enters the cycle of death. An absolute nothingness or a different state of consciousness where we keep learning to evolve more and more? Many philosophers have weaved theories about it, but the answer is simple: all are mere conjectures unable to really explain what happens when life comes to an end. Not even the apparently real stories of people who claim to have seen what there is after death have been able to clarify the most enigmatic mystery of the human race.
