WASHINGTON (AP) -- It may be the season for vampires, ghosts and zombies. Just remember, they're not real, warns physicist Costas Efthimiou.
Obviously, you might say.
But Efthimiou, a professor at the University of Central Florida, points to surveys that show American gullibility for the supernatural.
Using science and math, Efthimiou explains why it is ghosts can't walk among us while also gliding through walls, like Patrick Swayze in the movie "Ghost." That violates Newton's law of action and reaction. If ghosts walk, their feet apply force to the floor, but if they go through walls they are without substance, the professor says.
"So which is it? Are ghosts material or material-less?" he asks.
. . .
All this may seem obvious, but to Efthimiou and other scientists, the public often isn't as skeptical as you might think. Efthimiou points to National Science Foundation reports showing widespread belief in pseudosciences -- such as vampires, astrology and ESP.
More than 1 in 3 Americans believe houses can be haunted, a 2005 Gallup poll showed. More than 20 percent of Americans believe in witches and that people can communicate with the dead. TV shows such as "Medium" and "Ghost Whisperer" are popular.
"We're talking about a large fraction of the public that believes in subjects that scientists believe are out of the question," said Efthimiou. His paper is in an archive awaiting publication either in the journal Physics Education or the magazine Skeptical Inquirer, he said.
