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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

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 ...

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

(via PBS Space Time) Black holes are inevitable predictions of general relativity—our best theory of space, time and gravity. But they clash in multiple ways with quantum mechanics, our equally ...

A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with general relativity. Quantum mechanics is our best understanding of the ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...
