Time travel is deterministic and locally free, a paper says —resolving an age-old paradox. This follows research observing ...

Shattered glass does not leap back into your hand. Smoke from a match does not gather itself and crawl back inside. In ...

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 ...

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...

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 ...

Quantum computing has moved from lab curiosity to a technology that could reshape how humanity plans its most ambitious journeys into deep space. Instead of relying solely on brute-force rockets and ...

Cybersecurity experts often warn that a moment known as Q-Day is nearby—a day when quantum computers will become powerful enough to break all the encryption methods we currently rely on to keep our ...

Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no "butterfly effect." In the research, information—qubits, or quantum bits—'time ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...
