Actually scientist has been proving a lot of Buddhism beliefs and this time is about after death. Frankly speak it’s interesting.
Following death, according to Tibetan Buddhism, the spirit of the departed goes through a process lasting forty-nine days that is divided into three stages called "bardos." At the conclusion of the bardo, the person either enters nirvana or returns to Earth for rebirth.
It is imperative that the dying individual remain fully aware for as long as possible because the thoughts one has while passing over into death heavily influence the nature of both the after-death experience and, if one fails to achieve nirvana, the state of one's next incarnation.
Stage one of the Bardo (called the "Chikai" Bardo), the bardo of dying, begins at death and extends from half a day to four days. This is the period of time necessary for the departed to realize that they have dropped the body. The consciousness of the departed has an ecstatic experience of the primary "Clear White Light" at the death moment. Everyone gets at least a fleeting glimpse of the light. The more spiritually developed see it longer, and are able to go beyond it to a higher level of reality. The average person, however, drops into the lesser state of the secondary "clear light."
In stage two (called the "Chonyid" Bardo), the bardo of Luminous Mind, the departed encounters the hallucinations resulting from the karma created during life. Unless highly developed, the individual will feel that they are still in the body. The departed then encounters various apparitions, the "peaceful" and "wrathful" deities, that are actually personifications of human feelings and that, to successfully achieve nirvana, the deceased must encounter unflinchingly. Only the most evolved individuals can skip the bardo experience altogether and transit directly into a paradise realm. Stage three (called the "Sidpa" Bardo), the bardo of rebirth, is the process of reincarnation.
For most scientists what their experiment is just to prove the existent, the result. They will not act further after concluded the result and basically is just to acknowledge the result rather than act towards the result for a change of life. This is not what I concluded but was being told by a scientist friend. This is how they keep neutral of their experiment.
