Certainty Principles in Physics

Near-perfect physics. ‘Using better instruments and more powerful computers, scientists are demonstrating key aspects of physics with unprecedented precision. Three weeks ago, an international team showed how observations of an unusual double star system verify an effect predicted by Einstein’s general relativity to an accuracy of 99.95 percent. That leaves little wiggle room for doubts about Einstein’s theory of gravity. Thursday, another group reports a significant advance in laboratory experiments in teleportation. Quantum theory predicts that a particle can transfer – teleport – some of its properties to another particle when there is no discernable physical link between them. Highly precise experiments are turning that weird prediction, which was considered fiction only a decade ago, into observable fact.’
