Superconductivity Breakthrough: Frictionless Flow of Edge State Atoms

Physics, Science /

MIT scientists have successfully guided atoms into a unique “edge state” for the first time, enabling them to move without any friction. This breakthrough could pave the way for improved superconductor materials. When electrons pass through various materials, they experience varying degrees of resistance. Insulators block most movement, semiconductors permit some, conductors allow a significant

World’s First Nuclear Clock May Outperform Atomic Clocks

Experimental Physics, Physics /

Atomic clocks are currently the most precise timekeepers, losing only seconds over billions of years. However, nuclear clocks could potentially surpass them, enhancing GPS and internet technologies. Scientists have now developed and tested the first prototype nuclear clock. Atomic clocks measure time by counting the vibrations of specific atoms, which are highly consistent. For example,

Physics Discovery Predicts When a System Is Nearing a Critical Point

Physics /

As the myth goes, lemmings sometimes follow each other off cliffs to their doom. Imagine joining your fellow lemmings on a sunny mountain hike, enjoying the day—until suddenly, you plunge into the air, and everything goes black. The cliff’s edge represents what scientists refer to as a “critical point,” where a system’s behavior (like a

New Study Suggests Gravity Exists Without Mass

Physics, Quantum Physics /

What does gravity look like without mass? Newton’s groundbreaking laws universally define gravity’s effects, while Einstein’s concept of warped spacetime describes it in terms of curvature. Traditionally, scientists have associated gravity solely with matter A recent study proposes an unconventional idea: gravity could potentially exist without mass, offering an alternative to the concept of dark
