Three very old stars circling our galaxy... too old.

I found it interesting that you presented your question to AI in an "either/or" structure. 

Nevertheless, the AI response was complete in the sense that it reconciled the elements of the question in one answer.  I get that the answer to both elements of the question is "Technically yes. Why? 'Cause gravity generally sucks."...  But the synthesis of both such 'exclusionary' elements of the question in a single answer can be tricky... chalk one up for for a well-trained large language model.

LOL Im still trying to wrap the old noodle around, the properties of celestial motion which are mostly gravity till there is a collision, is it not? 

Even then what about stationary objects that are away from gravitational influence? Do they exist? or is everything perpetually in motion since the Big Bang?  

IIRC even the Big Bang, which was gospel in the GAPS circa 1970s is now theoretically being questioned.

and wasn't our particular swirl of the Milky Way supposed to merge with another galaxy(Andromeda?) relatively soon?

Lastly, do I detect a smirking response over the use of the Ask AI? I in no way am suggesting Ask AI is the end all be all, more it is a tool to point me in the right direction to get basic information quickly to delve into the deeper questions, such as dark matter. A theory that was virtually non-existent during my period of formal education, circa 1971-1984

here's how another AI site answered this question.

The solar system is moving with the Milky Way galaxy. Both the solar system and the Milky Way galaxy are moving through space, but the solar system's motion is primarily governed by the gravitational forces within the Milky Way galaxy.
Specifically:

1. The solar system orbits around the center of the Milky Way galaxy, completing one revolution approximately every 225-250 million years. This orbital motion is due to the gravitational pull of the supermassive black hole at the galactic center and the overall mass distribution of the galaxy.
   
2. Additionally, the entire Milky Way galaxy itself is moving through the intergalactic space at a velocity of around 600 km/s (1.3 million mph) relative to the cosmic microwave background radiation.
   
3. So while the solar system is orbiting within the Milky Way galaxy, it is also moving along with the entire galaxy as the Milky Way traverses through the cosmic expansion and the gravitational influences of other galaxy clusters.
   

In summary, the solar system is rotating and orbiting within the Milky Way, but this orbital motion is superimposed on the overall motion of the Milky Way galaxy itself through the larger universe.

"Our findings are statistically consistent with a head-on collision between the Andromeda galaxy and our Milky Way galaxy," said Roeland van der Marel of the Space Telescope Science Institute (STScI) in Baltimore.
The solution came through painstaking NASA Hubble Space Telescope measurements of the motion of Andromeda, which also is known as M31. The galaxy is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both.

This illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view and begins to distort the Milky Way with tidal pull.

The Big Bang is so widely accepted as the origin story of the universe that most people forget it is still a theory, and not proven fact. But new research led by astronomer Eric Lerner disputes the Big Bang, claiming that recent observations of light elements in the universe contradict the assumptions that support the theory.
The research was presented by Lerner on Wednesday at the 235th meeting of the American Astronomical Society in Honolulu, Hawaii.
