Quantum Tunnels Show How Particles Can Break the Speed of Light
Recent experiments show that particles should be able to go faster than light when they quantum mechanically “tunnel” through walls.
The Mathematical Structure of Particle Collisions Comes Into View
Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.
Why Gravity Is Not Like the Other Forces
We asked four physicists why gravity stands out among the forces of nature. We got four different answers.
‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles
Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.
What Goes On in a Proton? Quark Math Still Conflicts With Experiments.
Two ways of approximating the ultra-complicated math that governs quark particles have recently come into conflict, leaving physicists unsure what their decades-old theory predicts.
Graced With Knowledge, Mathematicians Seek to Understand
A landmark proof in computer science has also solved an important problem called the Connes embedding conjecture. Mathematicians are working to understand it.
Does Time Really Flow? New Clues Come From a Century-Old Approach to Math.
The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.
Why Do Matter Particles Come in Threes? A Physics Titan Weighs In.
Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern.
Wormholes Reveal a Way to Manipulate Black Hole Information in the Lab
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
