Maximum count for mutually bound stars

AI Thread Summary
In the early universe, there is no theoretical limit to the number of stars that can be mutually bound in a system, but the average size of these systems is expected to increase over time. The role of dark matter in binding systems is significant, as galaxies rely on both stars and dark matter for stability. In contrast, globular clusters, which primarily consist of old stars and lack detectable dark matter, represent some of the largest star-bound systems. These clusters tend to form in less dense regions, indicating a pattern in their distribution. Overall, the interaction between stars and dark matter is crucial in understanding the formation of bound star systems.

Especially in the early universe, what do you think would be the maximum number of stars bound in a system under mutual attraction?

I don't see any reason for a theoretical limit to this, though the growth of structure happens bottom-up, so the average size of bound star systems should increase with time. It also begs the question of whether you're allowing dark matter to assist in the binding. Galaxies are bound systems of stars, but it's not only the stars that do the binding. Globular clusters, on the other hand, do not have a detectable amount of dark matter, so they are probably the largest systems bound primarily by stars.
 
And they are composed of very old stars, and prefer the suburbs. I see a pattern emerging.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
