Amazingly, 54 years afters his death, it can be said that he might have been wrong.
Quantum physics is the study of the very small -- atoms, photons and other particles. Unlike the cause-and-effect of our everyday physical world, subatomic particles defy common sense and behave in wacky ways.
That includes the fact that a photon, which is a particle of light, exists in a haze of multiple behaviors. They spin in many ways, such as "up" or "down," at the same time. Even trickier, it's only when you take a peek -- by measuring it -- that the photon fixes into a particular state of spin. Stranger still is entanglement. When two photons get "entangled" they behave like a joint entity. Even when they're miles apart, if the spin of one particle is changed, the spin of the other instantly changes, too. This direct influence of one object on another distant one is called non-locality.
These peculiar properties have already been proven in a lab and tapped to improve data encryption. They could also one day be used to build much faster computers. Some philosophers see quantum phenomena as a sign of far greater unknown forces at work and it bolsters their view that a spiritual dimension exists.
