Abstract: There has been tremendous progress in the past few years on the measurements of the properties of neutron stars and black holes in our Galaxy. In this talk, I will discuss how these new advances are achieved and how they improve our understanding of fundamental physics. In particular, the radii measurements of neutron stars combined with measurements of pulsar masses already constrain the equation of state of ultradense matter well beyond what can be achieved by terrestrial nuclear experiments. Finding and weighing black holes, on the other hand, give us excellent tests of general relativity and shed light onto how massive stars evolve. I will conclude by discussing future observations that will further test physics in new regimes.
