What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already doing useful work. These sensors measure fields, forces and motion so small ...

Well, around a similar time, the American Physical Society (APS) invited researchers and science enthusiasts to chime in on ...

Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

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.

An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the journal ...
