The black hole nature of the compact objects in the currently known black hole X-ray binaries is inferred from the mass of the compact objects, with very rare clean evidence of strong gravity effects around the assumed black holes. The inclination angles of these systems, determined from optical and radio observations, range between 25 degrees and 80 degrees, and peak between 60-70 degrees. This peak is not explained in the frame work of Newtonian gravity in these systems. However, this peak is reproduced naturally if we model the observed X-ray radiations as being produced in the accretion disks very close to the black hole horizons, where the extremely strong general and special relativistic effects, caused by the extremely strong gravity near the black hole horizons, modify the local radiation significantly as the X-rays propagate to the remote observer. We argue that this is the evidence for the black hole nature of the compact objects in these systems.
