Abstract
No scientific study has been able to find evidence of an afterlife, and consciousness is still one of the most challenging questions. Here, I show a hypothesis for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence, yet I do precisely understand the mechanism. I found that consciousness might be discussed from three fundamental theories: quantum-level particles of neuronal function according to quantum mechanics; the brain, neurons, and molecules behave to general relativity, and a new theory is needed for ultraquantum particles. Simultaneously, a person or animal's death selection of a new neuronal system's quality of contemporary life might depend on the state of the finally evolving ultraquantum genome in the natural evolution of intelligence. Ultraquantum particles might emit and bond simultaneously with the suitable early nervous system or embryo when a brain dies.
