Black holes may not be as simple as we thought

 Black holes are objects in the universe known for their ability to absorb everything, including light and emit radiation. Unlike stars and planets they possess characteristics. Understanding holes relies on three main factors; mass, angular momentum and a concept known as "hair."

The concept of "hair" is a term used metaphorically to describe the information that black holes absorb or are composed of. Traditionally it has been believed that anything consumed by a hole is permanently lost and leaves no trace in the external universe.

However recent discoveries have challenged this notion. A groundbreaking collaborative study between the University of Southampton and the University of Cambridge has uncovered situations where black holes may actually release information back into space.

Without diving into the calculations performed by these scientists lets imagine a scenario where two black holes collide and merge. As they combine they accumulate matter to achieve a stable equilibrium resulting in an entity with multiple horizons while still obeying the laws of general relativity.

From our perspective, on Earth this merged entity would appear as a black hole.

This reveals the potential that the individual black holes we come across in the universe may hide complex mechanisms than we previously thought. This finding presents new opportunities for additional studies, in the field of cosmology.
