Would be nice if it were true but unfortunately there is no hard experimental evidence.
Quantum theory can be proved(using the slit filter light theory), the definite proof of quantum immortality is still a very grey hypothesis. Energy cannot be created or destroyed thus when the electrical energy ceases in the brain and cellular kinetic energy ceases it becomes potential and chemical energy(body decomposition)
It is is a nice concept, maybe one which explains previous lives(roman soldier etc) ghosts(energy trying to transfer to the next universe) but I am very sceptical, a friend once said to me 'Can you remember before you were born ?' I said 'No', his reply was 'It is like that when you die' A dispelling thought but is it true? Who knows, only we all will when that time happens
PS And who says us lot on here are just bassheads with no other interests LOL
