Evidence of Galactic Center Expansion from Gaia DR3 Stars along the South North Axis: Implications for the JWST Early Galaxy Problem
Recent observations with the James Webb Space Telescope (JWST) have revealed massive, evolved galaxies only a few hundred million years after the Big Bang, challenging standard cosmological models. To test the hypothesis that the Galactic nucleus may act as a source of matter and energy capable of accelerating galaxy formation, we examined whether the Milky Way itself shows signs of central activity. Expansion of the Galactic center would imply such activity in its nuclear region. To investigat…
