Exploring the Celestial Movements
The experts, through detailed observations, have explored the movement of pairs of satellites in the orbit of massive galaxies.
An Unexpected Cosmic Age
Standardized cosmogonic theories predict an age of the universe of 13.8 billion years, based on Big Bang models.
However, research shows that the dynamics of massive galaxy clusters could reveal a potentially younger universe.
Mysteries of the Cosmic Assembly
Traditional cosmological models suggest that small structures evolve through hierarchical mergers, leading to larger systems.
Observing the motions of satellites around massive galaxies provides crucial clues about the age of our universe.
SDSS Disclosure Data
By analyzing data from the Sloan Digital Sky Survey (SDSS), Professor Guo Qi and his team examined the kinematics of the satellite pairs.
Their findings, published in Nature Astronomy, indicate that estimates of the age of the universe may need revision.
Cosmic Consequences
The observations reveal an excess of satellite pairs with correlated motions, suggesting the recent arrival or infall of new satellite galaxies.
This discrepancy between observations and simulations implies that massive galaxy clusters could be younger than initially thought.
“The age of galaxy clusters may be directly linked to the age of the universe, potentially indicating a younger cosmos than the CMB of the Planck Collaboration suggests,” highlights Dr. Gu Qing, lead author of the study.
Challenge for Cosmic Models
These findings raise questions for the current cosmological model, offering valuable insights into the Hubble strain according to the study’s authors.
