A collapsar is another name for which astronomical phenomenon?
It was shown above that the Universe considered as a sphere of incompressible liquid is a collapsar.
According to one theory, known as the collapsar model, gravity rapidly crushes the core of a star at least 20 times as massive as the sun down to a black hole--a superlatively dense cinder whose gravity is so strong not even light can escape its grasp.
Obviously, only an extremely dense cosmic body can completely be located under its gravitational radius, thus consisting a gravitational collapsar (black hole).
