In a study published in the journal Classical and Quantum Gravity, researchers say the presence of wormholes helps resolve several problems with black holes, including the problem of singularity.

Gonzalo Olmo and colleagues from the University of Valencia and the University of Lisbon sought to analyse black holes using theories other than general relativity. Specifically, they considered the singularity as an imperfection in the geometric structure of space-time.

Black holes are regions in space with such a strong gravitational pull that nothing – not even light – can escape. Traditionally, it is thought the centre of a black hole contains a gravitational singularity.

This is a one-dimensional point where matter is crushed to an infinite density and the laws of physics as we know them no longer exist – a problem for scientists studying black holes.

To address the problem, Olmo applied geometric structures like crystal or graphene to black holes. “Just as crystals have imperfections in their microscopic structure, the central region of a black hole can be interpreted as an anomaly in space-time, which requires new geometric elements in order to be able to describe them more precisely,” he said. “We explored all possible options, taking inspiration from facts observed in nature.”
