New kind of black hole found that doesn't fit into the theory of relativity

Black holes can only be fully characterized by three physical quantities: their mass, spin, and charge.


Dr. Lior Burko of Theiss Research, in collaboration with Professor Gaurav Khanna of the University of Massachusetts at Dartmouth and the University of Rhode Island, along with his former student Dr. Subir Sabharwal, discovered that there is a special kind of black hole that has not been captured before.


The team used intensive numerical modeling: it involved the parallel use of dozens of high-performance NVIDIA graphics processing units (GPUs) with more than 5,000 cores each.


The authors of the paper investigated black holes "saturated" with the maximum charge or spin they could carry. They found that there is a quantity that can be constructed from the curvature of space-time at the black hole's horizon: it is conserved and can be measured by a distant observer. Because this quantity depends on how the black hole was formed, and not just on the three classical attributes, it violates its uniqueness.


This quantity is a gravitational hair. In the near future, scientists believe, it will be possible to measure it with new observatory equipment using scalar fields and spherical formations of objects. According to scientists, this conclusion is surprising because it applies to extreme black holes as well.
