New theory challenges singularity at black holes' core
This might change our understanding of the universe. Scientists have developed a theory that addresses the issue of singularity at the centre of black holes. It's one of the greatest mysteries of the cosmos, a point when all principles and theories seem to break down. Could this concept bring us closer to uncovering the cosmos' deepest secrets?
A team of scientists has proposed a new theory about black holes, which tackles one of the most challenging aspects of physics – the central singularity. This is the point where the density of matter and the curvature of spacetime become infinite. It's the place where all known laws of physics fail to work as we understand them.
Black holes have always been both mysterious and fascinating. Their event horizon, the outer boundary, is a surface from which not even light can escape. This means we cannot directly observe or measure what resides inside them.
Black holes may not have a central singularity
Einstein's theory of relativity states that objects with mass curve spacetime, and gravity arises from this curvature. The greater the mass, the more significant the curvature of spacetime, and the stronger the gravitational influence. However, Einstein's equations predict the existence of singularities, which poses a problem. According to the new theory, black holes may lack a central singularity.
They modified the theory that changed our understanding of the universe
According to the Lice Science portal, the team of scientists adjusted Einstein's equations so that gravity behaves differently in strongly curved spacetime. This results in the elimination of central singularities in black holes.
If the team's theory is correct, it could mean black holes are more ordinary than previously thought. However, as Hennigar notes, even if the concept of black holes without singularities proves true, it won't conclude the quest for a quantum theory of gravity and a theory of everything.
