Astronomers are investigating a controversial idea that black holes might be link to the universe’s accelerate expansion, driven by dark energy.
Dark energy, a mysterious force that forms about 70% of the universe, has long assume to spread evenly across space, pushing galaxies apart since shortly after the Big Bang.
A study publish in the Journal of Cosmology and Astroparticle Physics tilts towards a connection between dark energy and black holes.
This work has spark debates within the scientific community, presenting evidence that black holes, form by massive star collapses, might contribute to dark energy as they grow.
As per the research, the team use the Dark Energy Spectroscopic Instrument (DESI) on the Nicholas U. Mayall Telescope in Arizona.
As per report, the team analyse the data to estimate the amount of dark energy through the universe’s lifespan.
Their findings suggest a parallel increase in dark energy density with black hole mass over time.
Dr. Gregory Tarlé, a physics professor at the University of Michigan and co-author of the study, posits that gravity in black holes might mirror the universe’s early gravitational conditions.
He describes the process as a “reverse inflation,” where a massive star’s collapse could generate dark energy, acting like a reverse Big Bang.
If validate, this hypothesis could also address an ongoing mystery in cosmology call as the “Hubble tension”, the observation that different parts of the universe expand at different speeds, creating inconsistencies in current models.
The concept implies that black holes could influence these discrepancies.
Dr. Duncan Farrah, associate professor of physics at the University of Hawaii and co-author, said that the findings point to a “plausible” link, suggesting that black holes might indeed.
As the study offers promising leads, the team stresses that additional research with instruments like DESI will be essential to confirm these initial observations.
Dr. Gregory Tarlé explain that whether black holes contribute to dark energy is now “an experimental question,” marking a new chapter in our understanding of black holes and the forces shaping the cosmos.
