There are thousands of curious stars in our galaxy, called neutron stars, which are the size of a city but weigh as much as the sun. Gravity on a neutron star is 100 billion times stronger than on earth, atoms get crushed together to form strange types of nuclear matter, and their magnetic fields can be a staggering 1000 billion times stronger than a fridge magnet.

In this lecture, Anna Watts will explore why this weirdness makes them special. They allow us to study physics at the limits of our imagination: from gravity to magnets, and to the very tiniest particles that make up everything around us.
