Researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes quantum mechanics and relativity. more

Researchers propose a new holographic method to simulate black holes with a tabletop experiment. This work may be crucial for solving one of the biggest mysteries in science -- reconciling quantum mechanics and general relativity. more

In high school chemistry, we all learned about chemical reactions. But what brings two reacting molecules together? As explained to us by... more

The Einstein, Podolsky, and Rosen (EPR) entanglement, which features the essential difference between classical and quantum physics, has received wide theoretical and experimental attentions. Recently, the desire to understand and create quantum entanglement between particles such as spins,... more

Einstein's theory of general relativity predicts the existence of dark energy—a mysterious form of energy that permeates space and accelerates the expansion of the Universe. But what if Einstein was... more
