Recent scientific breakthroughs are making concepts once confined to science fiction, like time travel, seem tantalizingly ...

Time travel has long been a subject of fascination in science fiction, but recent scientific endeavors suggest that it might not be as far-fetched as once thought. Researchers in laboratories around ...

Circuit diagrams for (a) standard and (b) PCTC-powered weak-value amplification. Time progresses in the laboratory’s rest frame as one proceeds upward along the central, vertical axis. Black lines ...

In a makeshift lab, a trio of brainiac students argue over their time-travel device. The skeptic on the team has her doubts—not that the invention will work, but whether they should be mucking around ...

Most people see time as a one-directional arrow in the universe's symphony. But the world of theoretical quantum physicists is one in which the direction of time is far more flexible. These experts ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.
