A recent study from the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) proposes that black holes might not contain singularities. Published in Physics Letters B, the research describes "regular black holes" without singularities, negating the need for exotic matter previously considered essential.
The ICCUB team discovered that quantum gravity effects could eliminate singularities through corrections to Einstein's equations. This model relies solely on gravitational effects, simplifying previous theories that required exotic matter with negative energy.
Researchers tested their theory in a model universe with more than four dimensions, believing the findings applicable to our four-dimensional universe. The study indicates these singularity-free black holes adhere to the laws of thermodynamics, suggesting physical consistency.
The team plans to extend their work to a four-dimensional universe and study the behavior of these black holes in astrophysical scenarios. This research offers a new perspective on black holes and could provide insights into gravity and quantum mechanics.
