The “hairless” theorem states that black holes have only three distinct properties: mass, square momentum, and cost of electricity – the “hair” is a metaphor that applies to any building other than these three.
A new study by researchers from Theiss Research, the University of Massachusetts Dartmouth, and the University of Rhode Island shows that one particular type of black hole, in fact, goes against the principles of the “hairless” theorem.

A kink in the “no hair” theorem
The team focused on extreme black holes: a type of “saturated” black hole with the highest cost or spinning capacity.
They discovered that there is a size, or property, that can be taken from orbit during space during the horizon of the preserved black hole, and that can be measured from Earth.
Because this amount depends on the way the black hole is formed, and not on the three classical features, it contradicts the black hole homogeneity characterized by the “no hair” theorem. ”.
Gravitational hair
So much that the research team found makes up for “gravitational hair” that the research team says. They say it is measurable by recent and upcoming wave observations like LIGO and LISA.
“This new result is surprising because the unique black hole theories are well established, and in particular their extension to extreme black holes,” Dr Lior Burko from Theiss Research explains in a press release. “The theories that are unsatisfactory must be accepted, to explain how the theories do not apply in this case.”
“The particular theories embrace the independence of time. But the Aretakis phenomenon in particular contradicts the independence of time on the horizon of the event. This is the gap through which the hair can pop. out and combed at high speed with a tow wave observer, “he continues.
Combing for the mysteries of the cosmos
The team found the trace using intensive numerical symbols. They used dozens of Nvidia graphics processing units (GPUs) at their peak with more than 5,000 cores each, at the same time.
“Each of these GPUs can compute up to 7 trillion seconds; however, even with computing capability so the simulations look many weeks to complete,” he said. Gaurav Khanna of the University of Massachusetts Dartmouth.
The new study identifies new ways in which we can measure black holes and, with a surrogate, learn more about the mysteries of the cosmos.
