Discussion Overview

The discussion explores the concept of whether the universe could be likened to a giant spinning teacups ride, focusing on the implications of cosmic structures and their potential infinite hierarchy of orbits. Participants engage with ideas about the nature of cosmic rotation and the existence of a central point in the universe.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant suggests that if galaxies are orbiting super massive black holes, it raises the question of whether this chain of orbits is infinite.
  • Another participant counters that the idea of an infinite orbiting chain implies a center of rotation, which they argue does not exist in the universe.
  • Some participants express uncertainty about the initial claims and indicate that they are open to criticism of their ideas.
  • A later reply mentions that the question of a rotating universe has been previously discussed and often dismissed, suggesting a lack of consensus on the topic.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are competing views regarding the existence of a central point in the universe and the validity of the concept of a rotating universe.

Contextual Notes

Some claims depend on definitions of rotation and centrality in the universe, which remain unresolved in the discussion.

Moons orbit planets. Planets orbit stars. Stars sometimes orbit other stars. Stars orbit galactic centres. How to we know galaxies aren't orbiting super super super massive black holes or something along those lines. And it continues. How do we know this chain is not infinite?

Because it would imply a center around which everything rotates and there is no such center.

Also, are you aware that galaxies rotate in all different orientations relative to the disk of the Milky Way?
 
I vaguely understand what you mean, and need to say I don't nessercarily agree with what I have said, I am simply putting it forward to be criticised.

The question of a rotating universe has been addressed here several times, always shot down quickly.

What do you not understand about my post?
