You can say the universe has a split personality. Or better said, our physical models of the universe are the ones fractured.

Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one ...

But the experiments were set up in ways that meant we could only use them to determine that this superposition occurred in ...

Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research ...

The double-slit experiment is the best demonstration of quantum weirdness, in which electrons simultaneously act like particles and waves and seemingly violate basic laws of physics. Now we’re trying ...

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...
