Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime ...

Mind = blown.

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum theory—our two best bets on understanding the universe on a macroscopic and ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

Quantum gravity represents the ambitious quest to reconcile the principles of quantum mechanics with general relativity, aiming to produce a unified theoretical framework that can describe the ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...
