Study challenges Einstein’s relativity theory, finds instability in ****** holes

In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating ****** holes as per Einstein’s theory of general relativity.

These equations are collectively called

, and to this date, they represent one of the most accurate descriptions of rotating ****** holes.

However, a new study reveals that ****** holes are filled with instabilities, and what Kerr proposed is possibly not 100 percent accurate, especially about the internal structure of ****** holes.

“Our study implies that a ****** ***** cannot stabilize in Kerr geometry, at least over long timescales,” the study authors

with a power circular current that has two horizons. The first is the outer boundary known as the event horizon where the gravitational effect is so strong that it doesn’t let anything escape, not even light.

The second inner horizon, called the Cauchy horizon has a core called

, a region that becomes infinitely strong, and space and time break down. Its unique ring shape comes from the ****** *****’s spin, which stretches the singularity into a ring rather than collapsing it into a point.

“This model aligns well with observations, as deviations from Einstein’s theory outside the ****** ***** are regulated by new physics parameters, which govern the core’s size and are expected to be quite small,” the study authors said.

Kerr’s geometry suggests that

can store a vast amount of energy. However, according to the new study, as the energy inside ****** holes increases, it can bring drastic changes in their structure, leading to instability over longer timescales and even in short timeframes.

“This instability is due to an accumulation of energy that grows exponentially over time until it reaches a finite, but extremely large, value, capable of significantly influencing the overall geometry of the ****** ***** and thus altering it,” the study authors

. This further indicates that ****** holes are not as stable as proposed by the theory of general relativity.

A need for new theoretical models

Scientists are still not sure what happens when the energy buildup inside a ****** ***** reaches its peak, but if such an event happens it clearly means that the Kerr solution doesn’t fully explain the science that

.

“This result suggests that the Kerr solution, contrary to previous assumptions, cannot accurately describe observed ****** holes, at least on the typical timescales of their existence,” Stefano Liberati, one of the study authors and a professor at the International School for Advanced Studies (SISSA) in Italy, said.

They also believe that further studies focusing on the inner world and the above-mentioned instability of ****** holes could give rise to

that might overcome the limitations of the Kerr solution.

“The internal dynamics of ****** holes, which remain largely uncharted, could radically transform our understanding of these objects, even from an external perspective,” Raúl Carballo-Rubio, first author of the study and a postdoc researcher at the University of Southern Denmark, said.
