    Spinning Universe
AI Thread Summary
The discussion explores the concept of whether the universe could be likened to a giant spinning teacup ride, questioning the hierarchy of celestial bodies and their orbits. It highlights the chain of orbits from moons to galaxies, pondering if this chain could be infinite and what that implies about the universe's structure. Participants note that the absence of a central point of rotation challenges the idea of a rotating universe. Additionally, the orientation of galaxies relative to the Milky Way is mentioned, emphasizing the complexity of cosmic movements. The topic has been previously debated and generally dismissed in the forum.

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?

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
