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

Time travel has long lived in the realm of fantasy, but a growing body of research is quietly shifting it into a serious ...

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 ...

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

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

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

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 ...
