Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

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 ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...
