It looks like time travel, closed timelike curves, quantum mechanics, and quantum entanglement are once again at the centre ...

Physicists are rethinking one of quantum mechanics’ biggest puzzles: how fuzzy possibilities become definite reality. New ...

Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While ...

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in ...

New research suggests that if certain quantum collapse models linked to gravity are correct, time itself contains an inherent uncertainty, setting a fundamental limit on clock precision. While far too ...

A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use. Known ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist thanks to new research led by physicists at École Polytechnique Fédérale ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Researchers have confirmed 'negative time' in a quantum experiment where photons appeared to exit a rubidium atom cloud before entering it. First observed in the 1990s, the effect was verified using ...

A method that relies on hitting materials with neutrons can measure how much quantum entanglement hides within them, which ...

Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered ...
