Physicists Rewrite the Fundamental Law That Leads to Disorder
The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.
Puzzling Quantum Scenario Appears Not to Conserve Energy
By resolving a paradox about light in a box, researchers hope to clarify the concept of energy in quantum theory.
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.
Pondering the Bits That Build Space-Time and Brains
Vijay Balasubramanian investigates whether the fabric of the universe might be built from information, and what it means that physicists can even ask such a question.
Newly Measured Particle Seems Heavy Enough to Break Known Physics
A new analysis of W bosons suggests these particles are significantly heavier than predicted by the Standard Model of particle physics.
Massive Black Holes Shown to Act Like Quantum Particles
Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.
A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws
Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff.
The Mysterious Forces Inside the Nucleus Grow a Little Less Strange
The strong force holds protons and neutrons together, but the theory behind it is largely inscrutable. Two new approaches show how it works.
