A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Physics is generally built on observations, then the maths that supports them comes later. Columnist Karmela ...

Physicists use plasma physics to explore gravitational reconnection, a theoretical process that could reshape field ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s ...

Gravity is the force with which we’re most familiar. It’s what’s keeping you on the planet, even as you’re reading this. Despite gravity feeling deeply intertwined with our daily lives, scientists are ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

In the 1950s and earlier, the gravity theory of Einstein's general relativity was largely a theoretical science. In a new paper published in EPJ H, Jim Peebles, a physicist and theoretical cosmologist ...

Taken from the 25th anniversary issue of Physics World, this article examines one of the five biggest unanswered questions in physics as selected by the magazine’s editors The incompatibility of ...

Some people watch science fiction shows to be entertained, and that's fine. But you can also use them to find excellent physics problems. How about the recent Netflix movie Stowaway? It's about a crew ...
