Recent research has proposed that black holes might be the key to understanding dark energy, the mysterious force driving the universe's accelerating expansion.
A study published in the Journal of Cosmology and Astroparticle Physics suggests a concept called cosmological coupling
where black holes grow alongside the expanding universe, potentially generating dark energy.
The researchers, led by physicist Gregory Tarlé from the University of Michigan, argue that as black holes form—particularly during the collapse of massive stars—they may convert matter into dark energy, akin to a "little Big Bang" in reverse
This process could explain why dark energy has become dominant in the universe, accounting for about 70% of its total energy content.
Using data from the Dark Energy Spectroscopic Instrument (DESI), the team observed a correlation between black hole formation and changes in dark energy density over time.
This finding supports the idea that black holes are not merely passive entities but active participants in cosmic evolution, potentially reshaping our understanding of both dark energy and black holes themselves.
