Quark Quartet Fuels Quantum Feud
Newly discovered particles are forcing physicists to extend their simple picture of subatomic interactions or replace it with a more nuanced understanding.
At Multiverse Impasse, a New Theory of Scale
Physicists have begun to explore the idea that mass and length may not be fundamental properties of nature. The hypothesis could help to avoid the conclusion that our world is just a weird bubble in an endlessly foaming multiverse.
Fluid Tests Hint at Concrete Quantum Reality
Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.
Physicists Prove Surprising Rule of Threes
Three groups of experimentalists have independently observed a strange state of matter that forms from three particles of any type and at any scale, from practically infinitesimal to infinite.
Forging a Qubit to Rule Them All
A scientist at Bell Labs has started construction of a topological qubit, which could be the building block of a robust, scalable quantum computer.
Time’s Arrow Traced to Quantum Source
A new theory explains the seemingly irreversible arrow of time while yielding insights into entropy, quantum computers, black holes, and the past-future divide.
Betting on the Future of Quantum Gravity
New calculations suggest physicists may someday discover a fundamental theory of gravity, but it could require a radical new perspective on the universe.
Physicists Eye Quantum-Gravity Interface
Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.
A Jewel at the Heart of Quantum Physics
Physicists have discovered a jewel-shaped geometric object that challenges the notion that space and time are fundamental constituents of nature.
