After the Mana Vortex underwent a qualitative transformation due to the improved circulation of the [Everlasting Cosmos Revolving Sutra], Vaan felt like it wasn't much different from a black hole, at least in appearance.
Compared to a true black hole in the void, his Mana Vortex was considered very flat and linear in its disk-like rotation. On the other hand, a black hole was spherical and omnidirectional in its pulling force.
Of course, the biggest difference between a black hole and Vaan's Mana Vortex was their very nature. The former possessed gravitational power while the latter contained centrifugal force.
Gravitational force drew matter in while centrifugal force pushed it out; the two were not the same.
However, saying the two had no relationship was also incorrect.
The delicate balance between the two forces would create an orbit, allowing an object to revolve around another without crashing into it or flying off.
