This week and next, the Physics World Weekly podcast is dedicated to our Top Ten Breakthroughs in Physics for 2019.

This week we chat about the first five breakthroughs on our list. These are a new technology for converting thoughts into speech; the first images of a black hole event horizon; the first detection of a “Marsquake”; the discovery of symmetry violation in charm mesons; and a “Little Big Coil” that created a record-breaking magnetic field.
