No data was found concerning the details of the Great Exile. Our current understanding faces a black hole of an unspecified duration. It is impossible for us to know if this period called “ InterHistory ” lasted 500 years or 10.000 years. The assumption of a historical disinterest from emerging human groups living in a complete autarky is shared by a majority of researchers. Colonisation would have been done in the urgency and without any dialogue, each system being probably cut from the others for an unspecified duration.
The massive colonisation of the Universe probably took place during the Interhistory, undoubtedly a very long period in human History.
PROB FR VIRER "depuis peu"/ We know that the Universe is made of more than the O-galaxy, cradle of the humankind. There are a lot of hypothesis to explain the existence of inhabited planets in other galaxies. Anyway, the massive colonisation of the universe should have taken place during the Interhistory period. This period should have been a long periode in human History.
The so-called period of "Interhistory" ended around the first UTS year. The Universal Temporal Scale was adopted by the entire known universe, marking the new start of galactic communication in Origin. The History of other galaxies is still not really well known.
