Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

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 ...

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 ...

The study of relativistic effects in gravitational fields remains at the forefront of physics research, refining our comprehension of space‐time and its intricate interplay with matter. Notably, ...
