Neutron stars, the densest known objects in the visible universe, offer a unique opportunity to study matter under extreme conditions. Through multi-wavelength electromagnetic observations and gravitational waves, most notably from the binary neutron star merger event GW170817, researchers have made significant strides in understanding their interiors and evolution. These insights, coupled with nuclear theoretical calculations and experiments, provide critical constraints on the neutron star equation of state (EoS). In this lecture, I will explore our current knowledge of the EoS, while also discussing the potential of next-generation gravitational wave detectors to simultaneously probe the EoS and test theories of gravity beyond general relativity.
