Understanding the formation of galaxies is a complex topic, but recent research offers new perspectives. This guide explains the basics of a groundbreaking model proposed by scientists from Spain and Italy in January 2025, challenging traditional cosmological ideas.
The conventional understanding of galaxy formation relies on the inflation theory, which posits a rapid expansion of the early universe. However, the new model suggests that gravitational waves, stemming from quantum fluctuations, could have been the driving force behind the formation of the first galaxies. This shift in perspective requires a deeper understanding of the underlying physics.
According to the research, their model predicts specific outcomes that can be tested using future observations, such as those from the LISA space-based interferometer. If gravitational waves are detected, it would validate the theory and revolutionize our understanding of the cosmos. The study also highlights the significance of the James Webb Space Telescope in observing early galaxies, with the potential to confirm or refute the new model. Furthermore, the model suggests that the distribution of dark matter might be different than previously thought, which could influence how galaxies cluster together. This model offers a new framework for understanding the universe's evolution and provides a guide for future research in cosmology.
