Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at ...

A hundred times more than relativity theory -- "An act of desperation" -- The impudent Swabian -- The gypsy life -- Two pillars of wisdom -- The perfect instruments of the creator -- More heat than ...

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether Albert Einstein or Niels Bohr had the better grasp of the quantum world. Now a ...

Add Yahoo as a preferred source to see more of our stories on Google. Einstein–Rosen bridges are not wormholes but quantum links between opposite directions of time, offering new insight into black ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

Professional physicists, especially quantum physicists, were not much interested in the rumored coming of Einstein’s new field theory. They had made a decisive turn shortly after the Solvay Conference ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...
