Why quantum mechanics defies physics

The full, weird story of the quantum world is much too large for a single article, but the period from 1905, when Einstein first published his solution to the photoelectric puzzle, to the 1960s, when a complete, well-tested, ...

Why the universe might be a hologram

A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...

The strangest coincidence in physics: The AdS/CFT correspondence

Attempts to turn string theory into a workable theory of nature have led to the potential conclusion that our universe is a hologram—that what we perceive as three spatial dimensions is actually composed of only two. The ...

Quantum tool opens door to uncharted phenomena

Entanglement is a quantum phenomenon where the properties of two or more particles become interconnected in such a way that one cannot assign a definite state to each individual particle anymore. Rather, we have to consider ...

Acquitting a physicist accused of 'obscurantism'

American-born British theoretical physicist David Bohm made many significant contributions to physics. But he's most famous for challenging convention and interpreting quantum mechanics in terms of nonlocal or hidden variables. ...
