SUMMARY

The discussion centers on the claim that "space is falling faster than light" near a black hole, as mentioned by Andrew J. S. Hamilton in his river model analogy. This assertion is deemed almost meaningless, as it lacks a solid theoretical basis and raises questions about the interpretation of "space falling." The article referenced does not provide a clear explanation of the phenomena occurring inside a black hole, particularly beyond the event horizon, where the singularity resides. The analogy of a waterfall is criticized for its inaccuracy in representing the complexities of black hole physics.

PREREQUISITES
  • Understanding of general relativity and black hole physics
  • Familiarity with the concept of event horizons
  • Knowledge of the river model of black holes by Andrew J. S. Hamilton
  • Basic principles of spacetime and light speed limitations
NEXT STEPS
  • Research the implications of the event horizon in black hole theory
  • Study Andrew J. S. Hamilton's river model in detail
  • Explore the current theories regarding singularities and what occurs inside black holes
  • Investigate the relationship between mass, gravity, and spacetime curvature
USEFUL FOR

Astronomers, physicists, and students of astrophysics interested in the complexities of black hole dynamics and the theoretical implications of spacetime behavior near singularities.

In this article, in couple of places they mention about space moving faster than light. It's incorrect, right?

Hamilton also described them as places where space is falling faster than light.

Once you pass the horizon -- or go over Niagara Falls, in the waterfall analogy -- you would be falling faster than the speed of light toward the black hole's center -- called a singularity -- and feeling the effects, Hamilton said.

This assertion is almost meaningless. What is meant by "space falling"?

you would be falling faster than the speed of light toward the black hole's center

No one knows what happens inside a black hole - the assertion has no basis in any theory.
 
"I think of a black hole as rather like a waterfall, except it's not a fall of water but rather a fall of space... Once you pass the horizon -- or go over Niagara Falls, in the waterfall analogy -- you would be falling faster than the speed of light toward the black hole's center -- called a singularity -- and feeling the effects,” Hamilton said.

The relative size and state and dimension of Niagara Black Hole Mass Falls is grossly inaccurate.
Place an electromagnetic barrier out from across lip of Niagara Falls.

“Mass sucks” is tighter fit.
Consider poor rubber ducky lost down black hole drain in verse fluent vortex.
The speed of vortex by black hole drain exceeds even speed by ducky waves.

Please forgive.
