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 ...

One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental forces—electromagnetic, weak, and strong—have all been successfully described, but no complete ...

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research ...

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 ...

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 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.

When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications, from ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
