Searching for Black Holes in Space - the key role of X-ray observations
, 2013 Although General Relativity had provided the physical basis of black holes, evidence for their existence had to await the Space Era when X-ray observations first directed the attention of astronomers to the unusual binary stars Cygnus X-1 and A0620-00 ...
