90-year-old ‘second sound’ quantum theory observed in superfluid helium Physicists at MIT have achieved a major feat, capturing a bizarre quantum effect called second sound in superfluid helium. This breakthrough, based on a theory proposed nearly a century ago, sheds light on the fundamental behavior of quantum materials and opens up new possibilities for future […]
Physicists bring quantum mechanics and relativity closer to tame spinning electrons
Physicists Bring Quantum Mechanics and Relativity Closer to Tame Spinning Electrons For over a century, scientists have accepted an uneasy truth. Quantum mechanics and relativity, two fundamental pillars of modern physics, have coexisted without a unifying theory. Quantum mechanics describes the behavior of particles at the smallest scales, while relativity governs the laws of gravity […]
String theory’s nightmare: Ghostly five-particle family promises to uncover dark matter
String Theory’s Nightmare: Ghostly Five-Particle Family Promises to Uncover Dark Matter For decades, physicists have chased the dream of unifying all of nature’s forces under a single theoretical framework. One of the leading candidates for this ultimate unification is string theory, a complex and mathematically elegant proposal that posits the existence of tiny, vibrating strings […]
