Black holes are often described as the ultimate no-exit zones of the universe, where gravity becomes so strong that not even light can escape. However, what’s even more intriguing than the black holes themselves is what lies at their center.
According to Einstein’s theory of general relativity, if enough mass collapses under its own gravity, it forms a black hole with a central point known as the singularity. A singularity is a region where matter is thought to be compressed into an infinitely small space, resulting in infinite density and gravitational pull.
At this point, space and time, as we understand them, cease to function normally. This is where things get interesting. Singularity involves infinities, but infinities don’t make sense in physics. They signal that the equations of general relativity are no longer valid in extreme conditions.
This mismatch has haunted physicists for decades, leading scientists to explore alternative models that describe black holes without singularities. A new study from researchers at the Institute for Fundamental Physics of the Universe (IFPU) reveals two such promising models that, if proven, may help scientists get rid of black hole singularities for good.
