Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Generally speaking, black holes are regions of spacetime where matter is compressed into a tiny space. Dark matter, meanwhile ...

Cyclic cosmology, or the big bounce, is the idea that the universe will eventually crunch back together and then go through ...

What if the mysterious substance holding galaxies together is made of leftovers from a universe that existed before our own? That is the central question posed by physicists Carlo Rovelli and ...

A new model suggests the universe could tear itself apart as expansion accelerates, with quantum effects potentially driving ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...

Scientists confirm atom momentum entanglement for the first time, a mass-based quantum leap that could bring gravity and ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level ...

Quantum physicists at the Australian National University (ANU) have achieved a major milestone by directly observing atoms ...

The lack of convergence between quantum laws and gravitation remains a persistent problem in physics. A recent advance, ...
