Extragalactic origin confirmed
Cosmic rays — fast-moving, high-energy nuclei — pervade the Universe. We know that the lower-energy variety that we detect on Earth is funnelled by the solar wind. However, higher-energy cosmic […]
Ticking clocks
by Iulia Georgescu, Nature Physics 13, 529 (2017) doi:10.1038/nphys4169 (sci-hub) Special relativity assumes that laws of physics are the same in all reference frames, a principle known as Lorentz invariance. […]
Transparent perfect mirror
by Rachel Won, Nature Photonics 11, 331 (2017) doi:10.1038/nphoton.2017.90 (sci-hub – paper) Transparent ‘perfect’ mirrors — one-way mirrors that transmit or reflect light completely depending on the direction of view […]
Indefinite causality
Causality is a concept deeply rooted in our understanding of the world and lies at the basis of the very notion of time. It plays an essential role in our […]
