To date, no scientific study has found reliable evidence of an afterlife; the mechanism of consciousness is two of the most challenging questions. Here, I show the hypotheses for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence. I demonstrate the problems of consciousness, intelligence, and the brain's relationship with remaining neuroscience, physics, and psychology; and why new philosophy, physics, and psychology are needed to fulfill the gaps in the research objectives. Furthermore, I discuss how and why I suggest the strong probability of a continuum of consciousness -life after death. Findings show no alternatives other than the afterlife. In other words, I did not find different ways to discuss the results of those experiments yet. I discuss how and why new findings might help evolve well-being and make a better world.
