This experiment is different to the one that I recall hearing about a while back.
The one I remember was about a team who were allowing themselves to die, and would be left dead for a minute or so before being revived again. I can't remember the exact details of it, only that they were trying to find out what was after death and what the tunnel of light that people have reported seeing in NDE's really is.
There have also been studies conducted regarding the OBE and whether these experiments offered proof or not, due to the nature of the experiment, conclusive proof would remain in the mind of the believer or non-believer.
Such a challenge to the intellect, the reality of there being a life after death, or our spirit existing long after our body would mean people would have to start taking more responsibility for their actions and also start tapping into and partaking of religion. That is something many have closed hearts to.
