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 New Tool for Finding Dark Matter Digs Up Nothing
Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.
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.
