Wormholes, and Black Holes And Einstein, Oh My!
According to Einstein’s theory of general relativity, at the center of a black hole lies a point at which the forces of gravity are at their most intense, and time and space effectively end and based on that theory, if an object approaches the event horizon, it would be crushed in one direction, and stretched in another.
However, new research suggests that may not be the case, after all.
Now, a team of physists at the University of Lisbon in Portugal, have modeled what would happen to different objects, if each one ended up inside the spherical wormhole of a black hole.
Team memeber Diego Rubiera-Garcia explained “What we did was to reconsider a fundamental question on the relation between the gravity and the underlying structure of space-time. “What we did was to reconsider a fundamental question on the relation between the gravity and the underlying structure of space-time.”
Based on a theory first published last year by physicists from the University of Cambridge in the UK, the team argued that there’s no reason why a singularity necessarily has to be on the inside of a black hole and suggest that in a universe with five or more dimensions, which isn’t out of the question for us, a ‘naked’ singularly could exist, which is not bound by an event horizon.
The new study from Rubiera-Garcia’s team argue that if you remove singularity from a black hole, what you get in the centre instead is a finite-sized wormhole, and said “If naked singularities exist, general relativity breaks down, and if general relativity breaks down, it would throw everything upside down, because it would no longer have any predictive power. It could no longer be considered as a standalone theory to explain the Universe.”
