In a cafe at CERN in 1992, three physicists realized they disagreed about how many constants are needed to describe all of nature. A recent paper suggests only one – time – is necessary.

For decades, astronomers have been chasing unexplained bursts from the depths of space — powerful, fleeting, and precise. Could these “Wow-like” signals actually be traces of faster-than-light travel ...

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

Abstract: Motor imagery electroencephalogram (MI-EEG) classification is essential in brain-computer interface (BCI), and many classification methods have been proposed recently. However, the MI-EEG ...

Abstract: Space–time coding metasurfaces introduce a new degree of freedom (DOF) in the temporal domain, enabling advanced manipulation of electromagnetic (EM) waves, particularly in controlling waves ...
