Black holes and neutron stars are extremely compact astrophysical objects that are produced after the death of very massive stars. Due to their large compactness and popula tion\, such compact objects offer us excellent testbeds for probing fundam ental physics. In this talk\, I will focus on probing extreme (strong and dynamical-field) gravity that was previously inaccessible. Regarding black hole based tests of gravity\, I will explain how stringently one can prob e various fundamental pillars in General Relativity with the recently-disc overed gravitational wave events. Regarding neutron star based tests of gr avity\, I will use approximate universal relations ("\;I-Love-Q relati ons"\;) among certain neutron star observables that are almost insensi tive to the unknown stellar internal structure\, and describe how one can probe extreme gravity by combining future gravitational wave and binary pu lsar observations. I will conclude with a summary of important future dire ctions.
