ABSTRACT: In modern astrophysics, it is believed that galaxies are not expanding. The authors of the article set out to investigate the motion of Globular Clusters (GC) of the Milky Way relative to the plane and center of the Galaxy. The study yielded the following results: 1. The average velocity of the GC relative to the Galactic plane for the northern region of the Galaxy has a positive value of approximately 30.36 ± 15.29 km/s (N = 42) for the range

. 3. The average velocity of the GC relative to the Galactic center for the range 0 to 12 kpc is 31.70 ± 14.74 km/s (N = 119). Thus, we can state that the Galaxy is possibly expanding, at least in its central part. This seems unlikely as it does not agree with the current theory, so it can be considered a preliminary result requiring further study. However, if we accept the idea of the expansion of the Galaxy, we can answer a number of questions. In particular, we can explain the existence of massive galaxies discovered by the James Webb Space Telescope (JWST), whose age is estimated to be less than 1 billion years.
