Black Hole Singularities Might Not Exist

New research suggests a black hole doesn’t have a point of infinite density.

Roy Kerr is a legend. Back in 1963, the highly decorated mathematician from New Zealand found an exact solution to the field equations for Einstein’s General Relativity. This solution was the first to model a realistic, rotating black hole accurately. The importance of this cannot be understated. The General Relativity field equations are notoriously complex, and exact solutions that work in the real world and not just on paper are exceedingly difficult to find.

In 2023, Kerr built on his groundbreaking work and challenged physics titans like Stephen Hawking and Roger Penrose. His new idea was that black holes do not contain singularities, the points of infinite density in their centers. This flies in modern cosmology’s face and leads to profound consequences.

From Einstein to Schwarzchild

Einstein completed General Relativity in 1915. Though controversial at first, General Relativity is humanity’s best gravitational theory. Put simply, it states that matter and energy warp spacetime, the four-dimensional fabric of the universe. The more matter or energy there is, the more spacetime is warped. Gravity, then, should not be considered a fundamental force…
