The expansion of the universe is accelerating, but we’re not really sure why. The current best models give the driving force the placeholder name of “dark energy” – but that might not even exist. A ...

Black holesare known for their strong gravitational tugs, but gravity alone isn't enoughto send matter tumbling into the center of one. Magnetismprovides the final nudge, a new study finds.

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...

DR. STONER and all physicists interested in magnetism are to be congratulated on the appearance of this admirable monograph. In 1926, the author published a book on the same subject, “Magnetism and ...

Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage. QSLs also ...

The power of black holes to devour matter and light derives partly from magnetism, a new study shows. Black holes form when a star collapses on itself. Light gets trapped inside and the holes ...

Researchers at MIT have discovered a new type of matter, and a new type of magnetism - and say it could change the way computers store information. The breakthrough adds to the two previously known ...
