The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

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 ...

Einstein and the Quantum Revolutions Alain Aspect Univ. Chicago Press (2024) French physicist Alain Aspect is a pioneer in ‘quantum entanglement’ — connections between the quantum properties of ...

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.

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

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 ...

ONE snowy day last year, I trekked out of Vienna, Austria, winding my way to one of the city’s graveyards to visit the final resting place of a giant of 19th-century physics. Ludwig Boltzmann’s ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...
