For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles and fields. Both work brilliantly in their…
Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity. Space-time is frequently described as the “fabric of…
Earth will complete a rotation 1.33 milliseconds earlier than usual on Tuesday, August 5. That makes it one of the shortest days of 2025 at 86,399.99867 seconds long. How that happens, and how we can even measure it with…
La interacción fuerte es la responsable de la estabilidad de la materia. O sea, de que nosotros mismos, con todo lo que nos rodea, no nos desintegremos. Hablamos de la más intensa de las cuatro interacciones fundamentales de la naturaleza.…
Puisque l’Univers est en expansion, cela veut-il dire qu’il est parti d’un point précis, où il aurait été tout contracté ? Eh bien non ! Un physicien nous explique. Il y a environ un siècle, les scientifiques s’efforçaient de concilier ce qui…
Back in high school chemistry, I remember waiting with my bench partner for crystals to form on our stick in the cup of blue solution. Other groups around us jumped with joy when their crystals formed, but my group just…
European researchers are developing quantum computers using light and glass, in a collaboration that promises breakthroughs in computing power, battery technology and scientific discovery. Giulia Acconcia grew up in the picturesque, historic town of Spoleto, nestled in the foothills of…
Une nouvelle étude montre qu’il est possible de geler les positions des atomes qui constituent un matériau…, en le chauffant. Ce concept ouvre la voie au développement de dispositifs innovants, tels que des capteurs piézoélectriques capables de fonctionner à température…
A shard of smooth bone etched with irregular marks dating back 20,000 years puzzled archaeologists until they noticed something unique – the etchings, lines like tally marks, may have represented prime numbers. Similarly, a clay tablet from 1800 B.C.E. inscribed…
EU-funded researchers have brought supersolid light to life in the lab and are now exploring how this strange new state of matter could power real-world technologies. Can light ever be a solid? It turns out that, in the microscopic world…
