Live Science: Every night, amateur ghost-hunting groups across the country head out into abandoned warehouses, old buildings and cemeteries to look for ghosts. They often bring along electronic equipment that they believe helps them locate ghostly energy.
Despite years of efforts by ghost hunters on TV and in real life, we still do not have good proof that ghosts are real. Many ghost hunters believe that strong support for the existence of ghosts can be found in modern physics. Specifically, that Albert Einstein, one of the greatest scientific minds of all time, offered a scientific basis for the reality of ghosts.
