Over 2000 years ago people believed in the "laying on of hands" to heal many maladies. Although energy healers are still around, our more cynical "prove it" attitude tends to chalk up any improvements in physical condition to a placebo effect.
Ta-Da! Enter quantum physics and cell biology research.
A concept in quantum physics called "entanglement" is when one energy source entangles with another so that they interfere with each other. For instance, if you have a few pendulum clocks hanging on the wall and start them off at different times, after a while they will all swing in synchronicity.
In cell biology research, heart cells in a Petri dish will soon start beating in rhythm even when they aren't touching each other.
When you start to think about it, it's common knowledge that when a group of women are living together, eventually their menstrual cycles will coincide.
Some of the above information is from an interview done by Meryl Davis Landau. The subject of the interview is Bruce Lipton, PhD., author of "The Biology of Belief" and "Spontaneous Evolution". Dr. Lipton has worked as a cell biologist and as a professor at the National Institutes of Health, Stanford and the University of Wisconsin.
