Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human ...

Physicists are challenging long-held beliefs about time, suggesting it may not be a fundamental aspect of reality but rather ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

Some quantum systems may have two arrows of time, one running forwards as usual and another moving backwards. This means that, at some extremely small scales, time may have the option of moving in ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...
