There is an article on New Scientist's site about poltergeists.
Whenever I see this kind of subject in that kind of venue, I have conflicting feelings. One side says 'It's going to be another ridicule' and another says 'Maybe they're taking it seriously'.
I am also conscious of the date. It's April First. The article is timestamped 00:01, 1st April.
With that in mind, take a look at the physicists' explanation of the poltergeist phenomenon.
First impression - it's even crazier than the paranormal explanation.
Serious, or April fool? You decide.
