Are Ghosts Real? Science Says No-o-o-o

If you believe in ghosts, you’re not alone. Cultures all around the world believe in spirits that survive death to live in another realm. In fact, ghosts are among the most widely believed of paranormal phenomena: Millions of people are interested in ghosts, and a 2005 Gallup poll found that 37 percent of Americans believe in haunted houses — and nearly half believe in ghosts.

Ghosts have been a popular subject for millennia, appearing in countless stories, from the Bible to “Macbeth,” and even spawning their own folklore genre: ghost stories. Part of the reason is that belief in ghosts is part of a larger web of related paranormal beliefs, including near-death experience, life after death and spirit communication.

People have tried to (or claimed to) communicate with spirits for ages; in Victorian England, for example, it was fashionable for upper-crust ladies to hold séances in their parlors after tea and crumpets with friends. In America during the late 1800s, many psychic mediums claimed to speak to the dead — but were exposed as frauds by skeptical investigators such as Harry Houdini.

It wasn’t until the past decade that ghost hunting became a widespread interest around the world. Much of this is due to Syfy cable TV’s hit series “Ghost Hunters,” now in its 10th season of not finding good evidence for ghosts. The show spawned several spin-offs, including “Ghost Hunters International” and “Ghost Hunters Academy,” and it’s not hard to see why the show is so popular: the premise is that anyone can look for ghosts. The two original stars were ordinary guys (plumbers, in fact) who decided to look for evidence of spirits. Their message: You don’t need to be an egghead scientist, or even have any training in science or investigation. All you need is some free time, a dark place and maybe a few gadgets from an electronics store. If you look long enough, any unexplained light or noise might be evidence of ghosts.

The idea that the dead remain with us in spirit is an ancient one, and one that offers many people comfort; who doesn’t want to believe that our beloved but deceased family members aren’t looking out for us, or with us in our times of need? Most people believe in ghosts because of personal experience; they have seen or sensed some unexplained presence.

The science and logic of ghosts

Personal experience is one thing, but scientific evidence is another matter. Part of the difficulty in investigating ghosts is that there is not one universally agreed-upon definition of what a ghost is. Some believe that they are spirits of the dead who for whatever reason get “lost” on their way to The Other Side; others claim that ghosts are instead telepathic entities projected into the world from our minds.

Still others create their own special categories for different types of ghosts, such as poltergeists, residual hauntings, intelligent spirits and shadow people. Of course, it’s all made up, like speculating on the different races of fairies or dragons: there are as many types of ghosts as you want there to be.
