Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more ...

Theoretical breakthrough shows that time’s arrow can emerge naturally from how quantum parts become interconnected.

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

In a breakthrough that could transform the understanding of quantum magnetism, scientists have shown that a spinon, which was once believed to exist only in pairs, can travel alone. The discovery ...

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.
