This newer explanation, the so-called "direct collapse black hole model
," suggests that very large gas clouds - of between 10,000 and 100,000 solar masses - collapsed directly to become the seeds of the black holes.
in accordance with the black hole model
of the universe that is developed on the basis of this principle.
Not everyone buys the black hole model
of a quark-gluon plasma.
The remaining competitor to a black hole model
for the heavyweight centers of galaxies has been the superdense star cluster.
However, Russell Humphreys of Sandia National Laboratories formulated the White Hole Model
in 1995 for the origin of the universe based on two entirely different assumptions: The universe has a center somewhere, and it has finite boundaries.
Woosley has championed the supernova-black hole model
to explain gamma-ray bursts.
In accordance with the black hole model
of the universe developed recently by [21-22], a black hole constructs an individual spacetime (spatially singular and temporally noncausal to the outside) and a spacetime encloses a black hole.
Some theorists suggested reviving the black hole model
in the mid-1980s as improved ground-based, visible-light observations (though still lacking full resolution of the core) continued to indicate an intense spike of light coming from M15's center.
3 some open problems of the common black hole model
are pointed out and their relationship with the corresponding historical findings is emphasized.
The second group comprises three principal model approaches: cell, lattice, and Simha-Somcynsky hole models
Furthermore, tension has arisen between the observed characteristics of certain astrophysical phenomena and popular black hole models
