It is said that modern scientists are seriously arguing whether the God exists or not. The origin of the universe is near to be discovered. Many people believe science can explain any phenomena in the entire world.
However, it is difficult to prove the absence of supernatural powers. It is called "devil's proof." If you want to prove the existence of the devil, you need simply to show one. In contrast, regardless of your knowledge and experience, it is hardly proven that there are no devils in the world.
Brian Cox, a famous researcher of physics in the UK, told that he could clarify the absence of ghosts. He introduced Large Hardon Collider, the biggest particle accelerator in the world, to explain if ghosts existed it could have found them.
Independent: Ghosts definitely don't exist because otherwise the Large Hadron Collider would have found them, claims Brian Cox
Obviously, if ghosts exist, they must extract the power from some sources we have not discovered yet. And even if there are unnatural sources of power, they need to interact our organs of sense when we recognize ghosts. In this process, ghosts have to adhere the rule of physics.
This is the reason I do not believe the existence of ghosts. It is possible the grand principle of physics will be rewritten by an innovative discovery in the future. Nevertheless, the new principle will completely be consistent with the findings discussed ever.
