Rife machines work because of a principle in physics called sympathetic resonance.  It states that if there are two similar objects, and one of them is vibrating, the other will begin to vibrate as well, even if they are not touching.  Take the tuning forks in the picture to the right.  They are identical, tuning forks.  If you tap either one, it will sound like the note "C" on a piano.    If you tap one of these forks, the vibrations of that fork will pass through the air and cause the other tuning fork to vibrate. The energy from the first tuning fork has been transferred to the second tuning fork.  

    You may recall the commercial where Ella Fitzgerald sings a high note and causes a crystal glass to shatter.  This is the same principle at work.  Sympathetic resonance, if strong enough, can cause the receiving object to explode.

A PARASITE EXPLODES

Dr. Rife used this principle to destroy disease producing organisms.  He thought of every little micro-organism as a tiny little tuning fork.  He then built his Rife Machine to send out the signal that would cause the little bugs to vibrate.  By making the vibrations that came out of his Rife Machine stronger and stronger, he was able to shatter the micro-organisms at a distance.    Rife spent years of his life looking under his microscope, learning which frequencies would destroy which micro-organisms.
