Cosmologist, Sean Carroll, is the next in a long line of scientists to make headlines by claiming outright that there is no such thing as an afterlife or ghosts.
The physicist from the California Institute of Technology says, "the laws of physics underlying everyday life are completely understood" and everything happens within the realms of possibility. For there to be an afterlife, consciousness would need to be entirely separated from our physical body, which it is not.
Dr. Carroll says, "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."
Dr. Carroll's conclusion on human consciousness is routed in Quantum Field Theory, which states that there is one field for each type of particle. This means all of the photons in the universe are part of one field, all electrons make up another field, the same is true for gravitons and every other type of subatomic particle.
When we die our bodies decay but the particles that make us up aren't destroyed, they remain part of their respective quantum fields. So, in order for our consciousness to survived after death, it would need to exist as a quantum field of its own, but Dr. Carroll says that if that were the case we should be able to detect these "spirit particles" and "spirit forces."
You may be thinking, perhaps these "spirit particles" simply can't be detected. Well, that's possible but if they can't be detected then there is no way they could interact with regular atoms, this means their influence couldn't be felt by the human brain in order to give us consciousness and ghosts couldn't exist as they wouldn't be able to interact with their surroundings or reflect light making the visible to the naked eye.
Professor Brian Cox recently made a similar claim, stating that if some kind of spiritual energy existed the experiments at CERN (the European Center for Nuclear Research) should have detected it using the Large Hadron Collider (LHC), the world's biggest and most complex science experiment, a particle accelerator 17 miles in circumference built underground on the border of France and Switzerland.
Professor Cox said, "if we want some sort of pattern that carries information about our living cells to persist then we must specify precisely what medium carries that pattern and how it interacts with the matter particles out of which our bodies are made. We must, in other words, invent an extension to the Standard Model of Particle Physics that has escaped detection at the Large Hadron Collider. That's almost inconceivable at the energy scales typical of the particle interactions in our bodies."
Brian Cox spoke about the LHC on the BBC Radio 4 show, 'The Infinite Monkey Cage', the show's co-host Neil deGrasse Tyson clarified, "if I understand what you just declared, you just asserted that CERN, the European Center for Nuclear Research, disproved the existence of ghosts."
Brain replied, "Yes. I would say if there's some kind of substance that's driving our bodies, making my arms move and legs move, then it must interact with the particles out of which our bodies are made. And seeing as we've made high precision measurements of the ways that particles interact, then my assertion is there can be no such thing as an energy source that's driving our bodies."
If Dr. Carroll and Professor Cox are right, then all this means that there is no "life force" within us with its own distinct energy that can leave the body to live on as a ghost or spirit after the body has died.
