Abstract: This paper starts with the birth of Black Hole Binaries through major and minor mergers of galaxies accompanied with gravitational wave radiation. The formation of loss cone is described and if this loss cone is not replenished then the last parsec stalling of the merging BlackHole occurs. Spherical Symmetry, axi-symmetry and triaxial symmetry model of galaxies is described. Triaxiality ensures that loss cone is replenished and last parsec problem does not arise. Gravitational Wave Emission and their frequency range is described. Notable Black Hole Binaries are described. A century of Gravitational Wave Detection is described with the testing of Strong Equivalence Principle. Nano-Hz gravitational wave detection and their results are described.
