Could The Universe be Younger Than 13.8 Billion Years Old? #spacescience #astronomy #universe

Recent observations suggest the universe might be younger than the currently estimated 13.8 billion years. This hypothesis comes from the study of satellite galaxies' motions, which appear more recent than predicted. Traditional models, based on cosmic microwave background radiation data, depict a universe expanding due to dark energy and matter.

However, new measurements of galaxy pairs indicate more counter-rotating satellite galaxies than these models predict, suggesting a younger universe.

This discrepancy aligns with the "Hubble tension," where different methods yield varying expansion rates and, consequently, different universe ages. Resolving this could mean re-evaluating parts of the Standard Model or understanding dark matter differently, emphasizing the need for more data to clarify these cosmic mysteries.
