Dr. Sean Carroll, a professor of cosmology and physics at the California Institute of Technology, has announced his conclusion that life after death is not possible. Carroll said he has made that determination on the basis of principles of physics.
"The laws of physics underlying everyday life are completely understood," Carroll argued. "Claims that some form of consciousness persists after our bodies die and decay into their constituent atoms face one huge, insuperable obstacle: the laws of physics underlying everyday life are completely understood, and there's no way within those laws to allow for the information stored in our brains to persist after we die."
Carroll says that using Quantum Field Theory as a mathematical and conceptual framework, it lets us conclude that there is a "field" for every type of particle – photons, electrons, and anything else. There are no "spirit particles" that would allow human consciousness, or a soul, to be separated from the body, he reasoned.
"If it's really nothing but atoms and the known forces, there is clearly no way for the soul to survive death. Believing in life after death, to put it mildly, requires physics beyond the Standard Model," Carroll said.
