... The fundamental descriptions of black holes are based on equations in the theory of general relativity developed by the German-born physicist Albert Einstein. The theory was published in 1916. The gravitational force is strong near a black hole because all the black hole's matter is concentrated at ...

The x-ray emission intensity should exhibit rapid fluctuations because of the chaotic nature of the processes that cause the x-ray emission. • So, we search for binary systems in which (a) one of the objects is visible, (b) th ...
