At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

A microscopic clump of sodium has become the largest object ever to be observed as a wave, improving upon previous records by ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly ...

For a century, the Schrödinger equation has been the bedrock of quantum mechanics, successfully predicting how matter behaves as a wave. Yet, physics has lacked a fundamental explanation for why ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...
