What Happens When You Die?



Alongside the age old question regarding the meaning of life, what happens when you die is another one of those, seemingly unanswerable, questions most of us will ask ourselves at various points throughout our lives. The reason for such a morbid question couldn’t be simpler; it’s going to happen to each and every single one of us. Death is something we share with everyone and every living thing. We are born, we live, and we die.

To understand what happens when you die, we must first understand what death is. The dictionary definition of death is as concise at it is stark: The end of life; the total and permanent cessation of all the vital functions of an organism.

In times gone by, the end of life was determined to be when a person stopped breathing or when they no longer had a pulse. This resulted in many instances of people being declared dead when they were not, with some “miraculously” coming back from the dead – and others being buried alive. More recently, end of life has been determined to be when brain function has ceased. When your brain is gone, you are gone so to speak.

So, your brain has ceased functioning, you’ve stopped breathing and you have no pulse. To put it bluntly, you are dead. What happens now?

Many different cultures and religions have their own opinions on what happens when you die, but the majority of them all have one thing in common; the belief in an afterlife. What that afterlife is differs according to which religion you follow. The afterlife, or “Heaven” is prevalent in all of the major religions, but the details vary from one religion to the next. Christianity tells of a heaven of eternal life, living together with God and one another in peace and harmony. Many other religions, including Islam and Hinduism, tell us of a heaven of many levels. The better you did in life, the higher you will rise in heaven. The Buddhist religion takes that one step further, explaining that residence in heaven is temporary, with a rebirth as humans or animals signalling the start of a new life.

The belief in rebirth, or reincarnation as it is more widely known, is not limited to the Buddhist faith, or even religion in general. Films such as What Dreams May Come and Made In Heaven(a personal favourite!) have helped fuel speculation about reincarnation and the afterlife among the more general population.

In addition to the combination of religious belief and popular culture creating a widely-held belief in life after death, the “Near Death Experience”, or NDE, has cemented that belief even further. A Near Death Experience is a varying set of experiences reported by some people who have nearly died and been brought back, usually by resuscitation.

Many people who have experienced a NDE have reported seeing an intensely bright, white light at the end of a tunnel. Others have reported seeing long dead family members and friends, while some people have reported seeing their body below them while they float above it.

The plurality of experiences might suggest there is something to the notion of life after death, but an almost complete lack of physical evidence would tend to suggest otherwise…

Religious belief in an afterlife requires no evidence for the believer. Religion is built on faith and no amount of evidence to the contrary will sway those who firmly believe they are going to a better place after death. This is not necessarily a bad thing. Such a belief gives comfort to millions and lets them concentrate on living their life while not having to worry about what comes afterward.

What about the Near Death Experiences? The term “near death” gives a huge clue as to what might be happening here. The (vast) majority of people who have experienced them were not actually dead, but simply “nearly” dead. The visions of seeing loved ones are more than likely no different to the dreams we experience when sleeping. By the same token, seeing your body while floating above it could also be a result of dreaming coupled together with the captured senses of the environment around you. Your unconscious self may not be aware of what’s going on around you, but your brain will still be collecting the sounds, smells and sometimes the sights of that environment.

The staple of the NDE, the white light at the end of a tunnel, may also now have a less exciting explanation than confirmation of life after death. Scientists believe this sensation is triggered as a result of the brain shutting down and being starved of oxygen. Tests in high gravity environments have shown that our eyes naturally create a tunnel effect when they start to lose oxygen, so seeing a white light at the end of a tunnel when close to death suddenly becomes much less enigmatic.

For all that is written about life after death, there is not a single shred of verifiable evidence to confirm that we, or more specifically our souls, live on after our bodies have died. In those instances where people claim to have found proof of it, a cursory look at their data reveals shoddy research, vague assumptions and a distinct lack of objectivity.

We’ll be looking at some of those claims in a future article, but assuming what happens after you die is nothing, why should this be a reason for so much concern in the first place?

Multi-award-winning writer/comedian Ricky Gervais said it best; You remember what it felt like for the 14 billion years before you were born? It’s exactly like that.

Stephen Hawking: Heaven a fairy story


Stephen HawkingEnglish theoretical physicist and cosmologist Stephen Hawking has described heaven as a “fairy story for people afraid of the dark”.

His comments came in an interview with Ian Sample, science correspondent for the Guardian newspaper in the UK.

Hawking has experienced a number of health scares since being diagnosed with life threatening motor neurone disease when he was 21, the most recent when he was hospitalised in the US in 2009.

When asked in the interview what, if anything he feared about death, Hawking replied:

“I have lived with the prospect of an early death for the last 49 years. I’m not afraid of death, but I’m in no hurry to die. I have so much I want to do first. I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.”

Such as statement is not likely to go down well those who have a belief in God or are swayed by religion. Stephen Hawking ruffled feathers only last year with his book The Grand Design, where he wrote:

“Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God…”

Put in the simplest terms, there is a very high probability that he is right. If he isn’t, then we all win. If he is correct, what does it matter anyway? If, after death, there is simply nothing, we won’t be aware of it so there’s no real reason to fear it. We weren’t aware of the 13 billion years that had already passed before we were born, so the chances are pretty high that the next 13 billion will be exactly the same.

One thing is for certain. Stephen Hawking possesses quite possibly the greatest mind of our times. When he speaks, we should listen.
