SUMMARY
The influence of dark matter at the periphery of galaxies, specifically at a distance of 50,000 light-years from the center of the Milky Way, is significant. The acceleration due to gravity from dark matter is approximately 80% to 90% stronger than that from visible matter. Observations indicate that at around 50 kiloparsecs (kpc), the distribution of dark matter to visible matter is roughly 25% to 75%. This suggests that while both types of matter exert influence at this distance, dark matter becomes increasingly dominant as one moves further from the galactic center.
