There is no longer any question, the afterlife is real ..... Objective clinical evidence has now proven post-mortem consciousness survival to be a scientific fact.
Objective evidence is the gold standard for scientific proofs, and now we have unequivocal objective clinical data proving that Post Mortem Consciousness Survival is real. Indeed, The individual consciousness (spirit, soul) has been proven to survive the death of the physical body, and movies on to occupy an alternative dimension.
While we can not say "where" that alternative dimension is located in the spacial sense of 3-D, yet, the fact that consciousness continues to operate in an undiscerned "location", while the brain is not functioning and the heart is stopped, proves that a functioning brain is not required to support consciousness.
Also, the discovery of Dark Energy and Dark Matter proves that Classical Materialist science is currently unable to discern 96% of the universe. String theory postulates that this undiscerned Dark Energy and Dark Matter must contain eight additional dimensions. ... This leaves a lot of "room" and great deal of cosmic energy for surviving consciousnesses to persist within.
Finally, real After Death Communications-ADC has been proven to occur between individual post mortem surviving consciousnesses and consciousnesses still living in the physical, through the parallel phenomenon of Evidential Mediumship and poltergeist activities.
