Alternative gravity theory offers possible explanation for dark energy changing over time
Researchers at Istanbul Technical University have developed an alternative gravity theory suggesting that dark energy may have evolved over time rather than remaining constant. This finding challenges the traditional cosmological view and aligns with recent data from the Dark Energy Spectroscopic Instrument.
Why it matters
Understanding the nature of dark energy is fundamental to cosmology and our comprehension of the universe's expansion and ultimate fate.

Add to Preferred Sources Credit: Unsplash/CC0 Public Domain For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is thought to have behaved in the same way at every epoch. However, an increasing number of observations are challenging this idea.
Data from the Dark Energy Spectroscopic Instrument (DESI), which is creating the largest three-dimensional map of the universe, suggest that dark energy's effect might have evolved over time.
