Spooky Science

Quantum entanglement is just spooky - even Einstein thought so. As if particles (as in particle physics) have telepathic empathy.
The theory of quantum mechanics predicts that two or more particles can become "entangled" so that even after they are separated in space, when an action is performed on one particle, the other particle responds immediately. Scientists still don't know how the particles send these instantaneous messages to each other, but somehow, once they are entwined, they retain a fundamental connection.
This bizarre idea riled Einstein so much he called it "spooky action at a distance."
A new study found that this eerie quantum link can apply even to situations that resemble the larger, everyday world. Scientists entangled two pairs of vibrating particles separated in space, so that when one pair was forced to change its movement, the other pair did as well.
