NDEs: Science Fails to Settle Debate on Afterlife

NDEs: When the Brain Shuts Down, Consciousness Persists

In recent years, near-death experiences (NDEs) have moved from a marginal topic to dominating discussions in social media and news outlets. The popularization of testimonies like that of neurosurgeon Eben Alexander, who claimed to have had an NDE during a coma, has peine a question that materialist science believed was settled: what happens when the brain shuts down? The phenomenon, which affects millions of people worldwide, still lacks a unanimous explanation.

Hypoxia and Brain Damage: The Skeptical Explanation

The most widespread view in the scientific community holds that NDEs are the result of hypoxia, trauma, or hemorrhage suffered by patients. When the brain runs out of oxygen, a "chemical soup" is produced that generates hallucinations. A strong blow, such as one received by a boxer, can cause unconscious states with similar visions. However, this theory has a weak point: hallucinations due to hypoxia are usually disjointed and nonsensical, while NDE accounts present notable consistency, with recurring elements such as tunnel light, feelings of peace, or encounters with loved ones.

Testimonies That Challenge Neurological Explanations

There are documented cases of NDEs with flat electroencephalograms, meaning the brain was inactive. Surgeon Manuel Sans Segarra has analyzed several of these cases, arguing that there is a difference between hallucinations and pure NDEs. One of the most cited testimonies is that of a patient who, after a fall, spent several minutes in brain death and then described an overhead view of the hospital room, similar to a camera shot in an action movie. Other accounts include the ability to repeat conversations among surgeons or describe adjacent rooms impossible to see from the patient's position.

Reincarnation and the "Other Side"

The debate extends to reincarnation, which some consider the most logical explanation according to Occam's razor. Some argue that we live dozens of times, even on other planets. Authors like Michael Newton, Brian Weiss, or Raymond Moody have popularized this idea with books like *Many Lives, Many Masters* or *Life After Life*. However, the scientific community remains skeptical, and the discussion gets tangled in a terrain where empirical evidence is difficult to obtain.

The Paradox of Nothingness

One of the most unsettling testimonies is that of someone who claims to have been dead several times and seen "absolute nothingness." A darkness that does not exist in normal life and cannot be described in words. But, as has been pointed out, to see nothingness requires a consciousness that perceives it. And here the paradox arises: if there is something seeing, then there is something. The discussion becomes philosophical. The term "Eigengrau," the shade seen when closing your eyes in the dark, has even been mentioned to argue that pure black does not exist. Nothingness, ultimately, is a concept, not an experience.

The analysis stalls at one point: there is no way to verify what comes next, but the consistency of the accounts and cases with zero brain activity keep the door open. Meanwhile, the only certainty is that death remains the last taboo, and that every NDE testimony, whether real or a product of the brain, forces us to look into the abyss with different eyes.
