The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery -- and physicists are deeply divided about what is actually going ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

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 ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Scientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

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.

In commemoration of the 100th anniversary of modern quantum mechanics, a survey asked physicists for their takes on some hot questions in quantum theory.

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics. Paradoxically, his theory of relativity has become an essential tool for ...

Breakthrough battery lets physicists reverse entanglement—and rewrite quantum law Date: July 7, 2025 Source: University of Warsaw, Faculty of Physics Summary: Scientists have finally uncovered a ...

Finally answering the most-vexed question in quantum theory might mean redefining what is real.
