Do you think that gravitational theories also explain the orbits of binary stars or the dynamics of star clusters?
Well first you got to get what they are correct.
"The formation of globular clusters remains a poorly understood phenomenon and it remains uncertain whether the stars in a globular cluster form in a single generation or are spawned across multiple generations over a period of several hundred million years. In many globular clusters, most of the stars are at approximately the same stage in
stellar evolution, suggesting that they formed at about the same time. However, the star formation history varies from cluster to cluster, with some clusters showing distinct populations of stars"
They haven't a clue as to star formation, because they do not yet understand stars. Stars have moved across the HR diagram in a matter of months - when their lifespan is supposed to be measured in millions of years.

""We don't often see stars change their spectral types in a human lifetime. Thus, FG Sagittae, which brightened, cooled from about BO to K, and added lines of carbon, barium, and other elements to its spectrum in the century after 1890 was long seemingly unique. The standard interpretation has been that it experienced its very last flash of helium shell burning (the products are carbon and oxygen) and was about to become an R Coronea Borealis variable. These are carbon-rich stars that fade suddenly and unpredictably (which FG Sge started doing a couple of years ago) and that have hydrogen-depleted atmospheres (which FG Sge has just developed). In addition, the "galloping giant" is no longer alone. Examination of old images and spectrograms reveal that
V 605 Aquilae, studied by Knut Lundmark in the 1920's was a similar sort of beast, though it is now very faint And the latest recruit is
V 4334 Sagittarii, better known as Sakurai's object, for its 1994 discoverer. It, too, changed both spectral type and surface composition very rapidly, and is now hydrogen-poor and carbon-rich, and well on its way to becoming the century's third new R CrB star."
""V838 Mon was discovered to be in outburst in January of this year. Initially thought to be a familiar type of classical nova, astronomers quickly realized that instead, V838 Mon may be a totally new addition to the astronomical zoo. Observations indicate that the erupting star
transformed itself over a period of months from a small under-luminous star a little hotter than the Sun, to a highly-luminous, cool supergiant star undergoing rapid and complex brightness changes. The transformation
defies the conventional understanding of stellar life cycles. A most notable feature of V838 Mon is the "expanding" nebula which now appears to surround it." [Ital and emphasis added.]"
But if you are willing to face up to the fact that none of their observations match theory there is room for discussion. Including the discovered binary after each fissioning process.
