Discussion Overview

The discussion centers around the claim that space is falling faster than light near a black hole, as mentioned in a CNN article. Participants explore the implications of this assertion and its validity within the context of black hole physics, particularly focusing on theoretical models and analogies used to describe black holes.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants question the meaning of "space falling" and argue that the assertion of space falling faster than light is almost meaningless.
  • One participant highlights that no one knows what happens inside a black hole, suggesting that the assertion lacks a basis in any theory.
  • Another participant references Hamilton's river model of black holes, indicating that the article may be drawing from this theoretical framework.
  • A participant critiques the analogy of a black hole to a waterfall, arguing that it oversimplifies the complexities of black hole physics and presents inaccuracies regarding the nature of mass and gravitational effects.
  • There is a metaphorical discussion involving a rubber ducky and a vortex, illustrating the perceived differences in speed and behavior near a black hole.

Areas of Agreement / Disagreement

Participants express disagreement regarding the interpretation of space falling faster than light, with no consensus reached on the validity of the claim or the adequacy of the analogies used to describe black holes.

Contextual Notes

The discussion reveals limitations in understanding the nature of black holes and the assumptions underlying various models and analogies. Participants highlight the need for clarity in terminology and the speculative nature of claims regarding black hole interiors.

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.

space is falling faster than light
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.
