"...a "rewind protocol" enables any particle, such as an electron or proton, to revert to different quantum states from different points in time." by Svetlana Ekimenko via sputniknews The possibility of time travel – the concept of movement between certain points in time – has long captivated the minds of both scientists and science fiction writers alike. Scientific theories about time travel abound, interspersed with terms like wormholes, black holes, and space-time warp. "We have made science fiction come true," a collaboration of scientists has announced, claiming they have discovered a trick to speed up time. "It's possible to "accelerate, decelerate and reverse the flow of time within arbitrary, even uncontrolled quantum systems," Spanish researchers Miguel Navascués and David Trillo, from the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW), along with Austrian researcher Philip Walther, and the University of Vienna's
