A look back at three of the biggest stories in physics this year, including evidence that dark energy may be weakening, the discovery of a supersolid, and new advances in quantum geometry.

Marletto explains why traditional approaches to physics fail in important cases such as information theory, and how constructor theory might succeed.

Quantum computers aren’t the next generation of supercomputers — they’re something else entirely. Before we can even begin to talk about their potential applications, we need to understand the fundamental physics that drives the theory of quantum computing.

Leonard Susskind and collaborators set out to understand why black hole interiors grow forever. They ended up proposing a new law of physics.

In 2025, physicists spotted a paradigm-shifting new black hole, doubled down on weakening dark energy, and discovered that the Earth’s deep interior may be more connected than previously thought, reshaping our picture of the planet’s engine.

Nima Arkani-Hamed makes his “big-picture” case for building a 100-TeV particle collider.

David Moore of Stanford University describes how, inside this chamber, silica spheres probe for distortions of gravity.

Helen Quinn has blazed a singular path from the early days of the Standard Model to the latest overhaul of science education in the United States.

The phenomenon of criticality can explain the sudden emergence of new properties in a wide range of complex systems, from avalanches to flocks of birds to stock market crashes. Neuroscientists are now seeking evidence that criticality is at work in the brain’s networks of neurons.
