For decades near-death experiences like Jeanette’s have been written off as delusions by scientists. They are dismissed as no more than the last twitches of a dying brain. Modern science has no place for mysticism and the paranormal. But now a group of British researchers are challenging the scientific establishment by launching a major study into near-death experiences. They hope to settle once and for all the question of whether there truly is life after death.

“We now have the technology and scientific knowledge to begin exploring the ultimate question,” says Dr Sam Parnia, leader of the research team at London’s Hammersmith Hospital. “To be honest, I started off as a sceptic but having weighed up all the evidence I now think that there is something going on.

As soon as a patient slips into a cardiac arrest, Dr Parnia’s team will swing into action. The first priority will be to get the patient’s heart beating again. Equipment used during the resuscitation will have symbols placed on top of it in such a way that they can only be seen from above. Other symbols will be placed around the patient’s body.

Surviving patients will then be gently quizzed about their experiences when they regain consciousness. Those that claim to have left their bodies will be questioned in more detail to see if they can identify the symbols.

Dr Parnia has designed the experiments to be bullet-proof. He is only too keenly aware that critics will tear his work apart if he leaves even the slightest doubt about the rigour of his team’s efforts. It will also destroy his career as a scientist. Even the exact experimental details are shrouded in secrecy.
