And blackly amid the white swell
A gaping chasm its jaws opens wide,
As if leading down to the depths of hell:
And the howling billows are seen by each eye
Down the whirling funnel all madly to fly.
"The Driver" by Friedrich von Schiller

In science:

It also leads to a generalization of the zeroth and first laws of black hole mechanics.
Gravitational radiation of generic isolated horizons
This leads to the possibility that black holes may be more usefully defined in terms of trapping horizons.
Black holes and black hole thermodynamics without event horizons
However, the requirement that the horizon should be stationary leads to the requirement that it should be null too and this places strong constraints on the possibility of constructing such highly distorted stationary horizons. A partial answer to this problem is provided by the black hole uniqueness theorems.
Black holes and black hole thermodynamics without event horizons
Furthermore, Hawking showed that a black hole could lead to a breakdown of predictability since taking the trace over the unknowable interior state would turn an initially pure quantum state into a mixed thermal state .
Black holes and black hole thermodynamics without event horizons
The use of a black-body overestimates the stellar flux in the optical, which leads to an overestimate of the amount of attenuation required to reproduce the observed data.
The Physical Properties of the Red Supergiant WOH G64: The Largest Star Known?
Indeed, it is thought that this type of interaction can lead to the formation of blue stragglers (Glebbeek, Pols & Hurley 2008), and possibly intermediate mass black holes (Portegies Zwart et al. 2004).

As we will see, the exponential change of co-ordinates Eq.(1.5.2) leads to dramatic consequences for two-level spectral correlations, and has even a farreaching analogy in the physics of black holes [20, 22].

The mathematics involved in this phenomenon is fundamentally the same as the one which leads to the “no-hair-theorems” (see, eg., ) for the black hole.
Thermodynamical Aspects of Gravity: New insights
But the arguments given in the last section leading to the association of entropy — in contrast to the association of a temperature — cannot be easily generalized from black hole horizon to other horizons.
Thermodynamical Aspects of Gravity: New insights
That brings us to the crucial question: What are the microscopic states which one should count to obtain the result in Eq. (109) ? That is, what are the degrees of freedom which lead to this entropy ? To begin with, the thermal radiation surrounding the black hole has an entropy which one can compute.
Thermodynamical Aspects of Gravity: New insights
We recall that the mathematical formulation leading to the association of temperature with any horizon is fairly universal and it does not distinguish between different horizons, like, for example, Rindler horizon in flat space or a Schwarzschild black hole event horizon or a de Sitter horizon.
Thermodynamical Aspects of Gravity: New insights
Their considerations lead them to construct a bridge between Black Hole formation and the NC spacetime.
