I suspect that although from here globs look really compact, there is vast space between the stars. From any star the nearest star would be lightmonths or years away, while the diameter of the star would only be some lightseconds. So the stars would be tiny compared with the distances between them.

Then one could think of the interaction between the stars as interaction between very small particles. And if this picture is correct (= good enough) the stars would very rarely collide, and would orbit each other and their common centre of gravity. But I would like to know what is really going on, and what the best astronomical observations tell us.
