This series is found on YouTube and is a fairly comprehensive discussion of experiments conducted by scientists at the turn of the 20th century regarding proof of life after death. 

It seems they were able to do so, but no one took them seriously (least of all, fellow scientists) as the associated mathematics could not be found to prove their theory(s).  Physicist Ron Pearson believes he now has the mathematical proof for survival of the human spirit.

This series is an in-depth interview with Dr. Pearson and others involved in this quest, and you can find it by just searching under "the science of eternity".

A series of follow-up articles can be found here:
