World’s Fastest Electron Microscope, Quantum Consciousness and the Origin of Life Host Erika Hamden explores quantum mysteries. We visit a University of Arizona lab where the world’s fastest electron ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Yet it is not regarded as absurd today. After exhaustive proofs of entanglement's authenticity in the real world, it is now the key resource in quantum information theory, allowing quantum ...

A commemorative survey of quantum physicists revealed a lack of consensus on how best to interpret the strangeness of the quantum world. Credit: NSF/Daniel M. Harris, John W.M. Bush In July ...

Does quantum physics place limits on the extent to which we have free will? This long-debated question stems from the way different physicists interpret the mathematics of quantum theory, but now ...
