Quantum mechanics replaced the clockwork certainty of classical physics with something far stranger: a framework in which ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

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 ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Quantum key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the ...

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

Quantum physics may sound abstract, but Ph.D. candidates Kirsten Kanneworff and David Dechant show that quantum research can also be very concrete. Together, they are investigating how quantum ...

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

In the pantheon of modern physics, few figures can match the quiet authority of Gerard ’t Hooft. The theoretical physicist, now a professor emeritus at Utrecht University in the Netherlands, has spent ...

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

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 ...
