Can Science Explain Heaven?

Scientists try to explain near-death experiences.

There are those who believe that science will eventually explain everything—including our enduring belief in heaven. The thesis here is very simple: heaven is not a real place, or even a process or a supernatural event. It's something that happens in your brain as you die.

I first encountered this idea as I was researching my new book, Heaven: Our Enduring Fascination With the Afterlife. I was having lunch with my friend and colleague Christopher Dickey, who told me that his father, the writer James Dickey, had a fantasy of heaven in which all of his closest friends were sitting around a swimming pool, chatting. "There was nothing special about the pool itself," wrote Chris in Summer of Deliverance: A Memoir of Father and Son. "Nobody walked on the water. And he never told me who the friends were ... But what he took away from the dream was a sense of contentment, of being at ease with himself and the world, as if he had gotten a preview of heaven. He called that place 'The Happy Swimming Pool.' " Chris believes that everything we think we know about heaven happens in the moments before death. After that, there's nothing.

Science cannot definitively proof or disprove Chris's theory, but some scientists are willing to take guesses. And these guesses are based, in part, on a growing body of research around near-death experience (NDE). According to a 2000 article in The Lancet, between 9 and 18 percent of people who have been demonstrably near death report having had such an experience. And surveys of NDE accounts show great similarities in the details. People who have had NDEs describe—like some religious visionaries—a tunnel, a light, a gate, or a door, a sense of being out of the body, meeting people they know or have heard about, finding themselves in the presence of God, and then returning, changed.

Andrew Newberg is an associate professor in the radiology department at the University of Pennsylvania who has made his reputation studying the brain scans of religious people (nuns and monks) who have ecstatic experiences as they meditate. He believes the "tunnel" and "light" phenomena can be explained easily. As your eyesight fades, you lose the peripheral areas first, he hypothesizes. "That's why you'd have a tunnel sensation." If you see a bright light, that could be the central part of the visual system shutting down last.

Newberg puts forward the following scenario, which, he emphasizes, is guesswork. When people die, two parts of the brain, which usually work in opposition to each other, act cooperatively. The sympathetic nervous system—a web of nerves and neurons running through the spinal cord and spread to virtually every organ in the body—is responsible for arousal and excitement. It gets you ready for action. The parasympathetic system—with which the sympathetic system is entwined—calms you down and rejuvenates you. In life, the turning on of one system prompts the shutting down of the other. The sympathetic nervous system kicks in when a car cuts you off on the highway; the parasympathetic system is in charge as you're falling asleep. But in the brains of people reporting mystical experiences—and, perhaps, in death—both systems are fully "on," giving a person the sensation both of slowing down, being "out of body," and of seeing things vividly, including memories of important people and past events. Does Newberg believe, then, that visions of heaven are merely chemical-neurological events? He laughs nervously. "I don't know." He laughs again. "It's, um … I don't think we have enough evidence to say."

Since at least the 1980s, scientists have theorized that NDEs occur as a kind of physiological self-defense mechanism. In order to guard against damage during trauma, the brain releases protective chemicals that also happen to trigger intense hallucinations. This theory gained traction after scientists realized that virtually all the features of an NDE—a sense of moving through a tunnel, and "out of body" feeling, spiritual awe, visual hallucinations, and intense memories—can be reproduced with a stiff dose of ketamine, a horse tranquilizer frequently used as a party drug. In 2000, a psychiatrist named Karl Jansen wrote a book, Ketamine: Dreams and Realities, in which he interviewed a number of recreational users. One of them, who called himself K.U., describes one of his drug trips this way: "I came out into a golden Light. I rose into the Light and found myself having an unspoken interchange with the Light, which I believed to be God." Dante said it better, but the vision is astonishingly the same.

How to Digitally Record/Video a UFO sighting:


Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:




Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
