Humankind has peered into the star speckled night-sky for eons in search of a sister civilization harbouring intelligent life, and nothing has been found so far.
As a species journeys towards becoming the dominant lifeform over a planet, such as is seen on earth with humans at the top of the evolutionary pyramid, a myriad of problems threatening the survival of the collective crops up. The lack of basic necessities required for survival, namely food, water, energy and space could hinder the evolutionary progress of a civilization. If these fundamental requirements are not addressed chaos, and ultimately extinction is the inevitable destination for the collective.
The Trancension hypothesis indicates that when such a point is reached by any civilization, instead of choosing to journey out into outer-space in search of hospitable planets, the collective will choose to move into the inner boundless space offered by technology, and disappear into a miniature digitized world akin to a black hole.
