In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

For decades, you have heard scientists say that most of the universe is missing. They are not being dramatic. They mean it in a literal sense. A huge share of matter in the cosmos cannot be seen or ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

A gold sphere levitates over a semiconductor with an electrical bias. In new research, engineers at the University of California, Davis, have shown that biased semiconductors can control the Casimir ...

Before Einstein, before Bohr, there was a Jesuit priest with a telescope and a startlingly modern vision of the universe.
