"New Research Challenges Cosmic Expansion: Is the Universe Slowing Down?"

A new study from Yonsei University suggests that the universe may be slowing in its expansion, challenging the long-held belief in accelerating cosmic growth driven by dark energy.

• The research published in the Monthly Notices of the Royal Astronomical Society indicates that the expansion of the universe has entered a phase of deceleration at the current epoch.
• This study contradicts the prevailing Lambda-CDM model, which has long supported the idea of dark energy accelerating cosmic expansion since the Big Bang.
• Using data from the Dark Energy Spectroscopic Instrument, researchers analyzed supernova observations to assess the current rate of galaxy expansion and its implications for cosmology.
