We present a lesser known way to conceptualize stationary black holes, which we call the river model. In this model, space flows like a river through a flat background, while objects move through the river according to the rules of special relativity. In a spherical black hole, the river of space falls into the black hole at the Newtonian escape velocity, hitting the speed of light at the horizon. Inside the horizon, the river flows inward faster than light, carrying everything with it. The…

A river model of space

We expand on Hamilton and Lisle’s idea of a river model of black holes (Am. J. Phys. 76, 519 (2008)) by presenting a reformulation of the river description in terms of an orthonormal basis field

Strategies of motion under the black hole horizon

In this methodological paper, we consider two problems an astronaut faces under the black hole horizon in the Schwarzschild metric. (1) How to maximize the survival proper time. (2) How to make a

Zero-momentum trajectories inside a black hole and high energy particle collisions

We consider properties of the trajectory with the zero momentum inside a spherically symmetric black hole. We work mostly in the Painlevé -Gullstrand frame and use the concept of the “river model of

Insights into the Evolution of Horizons from Non-Orthogonal Temporal Coordinates

The introduction of coordinates representing the points of view of various observers results in the possibility of horizons when acceleration and gravitation are included. A horizon is a surface of

Regular frames and particle’s rotation near a black hole

We consider a particle moving towards a rotating black hole. We are interested in the number of its revolution n around a black hole. In our previous work (Pavlov and Zaslavskii in Gen Relativ Gravit

Black-Hole and White-Hole Horizons in Superfluids

Ripplons – gravity-capillary waves on the free surface of a liquid or at the interfaces between two superfluids – are the most favourable excitations for simulation of the general-relativistic

Flow and Peculiar Velocities for Generic Motion in Spherically Symmetric Black Holes

In this methodological paper we consider geodesic motion of particles in spherically symmetric black hole space-times.We develop an approach based on splitting the velocity of a freely falling

The black hole interior and the type II Weyl fermions

It was proposed recently that the black hole may undergo a transition to the state, where inside the horizon the Fermi surface is formed that reveals an analogy with the recently discovered type II

Black Holes: The Membrane Paradigm

The physics of black holes is explored in terms of a membrane paradigm which treats the event horizon as a two-dimensional membrane embedded in three-dimensional space. A 3+1 formalism is used to

The gravitational effects associated with the radiative tail produced by a gravitational collapse with rotation are investigated. It is shown that the infinite blueshift of the tail's energy density

Inside charged black holes. I. Baryons

An extensive investigation is made of the interior structure of self-similar accreting charged black holes. In this, the first of two papers, the black hole is assumed to accrete a charged,

It is a deceptively simple question to ask how acoustic disturbances propagate in a non-homogeneous flowing fluid. Subject to suitable restrictions, this question can be answered by invoking the

The Large Scale Structure of Space-Time

The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.

Vortex analogue for the equatorial geometry of the Kerr black hole

The spacetime geometry on the equatorial slice through a Kerr black hole is formally equivalent to the geometry felt by phonons entrained in a rotating fluid vortex. We analyse this example of

Novikov has developed a reference system built around radially moving geodesic clocks that allows particle and light signal trajectories to be followed across the Schwarzschild radius Rs. We utilize

Heuristic approach to the Schwarzschild geometry

In this article I present a simple Newtonian heuristic for motivating a weak-field approximation for the spacetime geometry of a point particle. The heuristic is based on Newtonian gravity, the
