I will update the review published in the proceedings of the first Accretion Processes in Cosmic Sources (APCS) 2016 workshop (Giovannelli & Sabau-Graziati, 2016). A part of the figures used are the same since there are no reasons to justify a drastic change in the structure of the present
However, it is my intention to show that every component of the Universe is bound to every other component and that the comfortable classifications that are usually used are nothing more than artifices to demonstrate their apparent diversity.
In reality, we move from "one class of cosmic sources" to another continuously.
In this review I will discuss the following arguments:
• Antecedent Fact
• Accretion in Young Stellar Objects
• Accretion in Planets
• Accretion in White Dwarfs
• Accretion in Neutron Stars and Black Holes
• Accretion onto the Oceans
• Accretion in the Space
