For years, physicists have theorized that some black holes might actually be wormholes, and new research shows that this is indeed possible. While wormholes, which are tunnels in the fabric of space-time that allow travel to another part of the universe, are mathematically possible, there is no evidence that they exist. The authors of a study published on the preprint server arXiv offer more evidence to support the theory that wormholes can masquerade as black holes, since the two objects have similar characteristics. Wormholes, tunnels in space-time that allow one to travel to another world, or more precisely, to another part of space relatively quickly, are still hypothetical objects. According to many theories, wormholes, also called wormholes, connect two points in the fabric of space-time that can be located at a huge distance from each other. Some physicists believe that these objects can be used to quickly travel not only between star systems, but also between galaxies. One of the first theoretical wormholes is the Einstein-Rosen bridge, but this is simply a certain solution to the Einstein field equations, which maps the geometry of space-time under certain conditions of matter and energy.

Because of the strangeness of spacetime required for a stable wormhole to form, some physicists have considered the possibility that some black holes might actually be wormholes in disguise. Although physics makes it nearly impossible for stable wormholes to exist, mathematics shows that it is possible. The authors of the new study analyzed a certain attribute of Schwarzschild black holes (hypothetical black holes that do not rotate and have no electric field) known as quasi-normal modes (QNMs). These modes are considered quasi-normal because they describe the characteristic oscillations of space-time when the compact object is disturbed, meaning they do not continue indefinitely. Using different approaches to analyze different types of perturbations, physicists have concluded that a wormhole can consistently reproduce the QNMs associated with static black holes. Scientists say wormholes are exotic compact objects that go beyond the predictions of Einstein’s general theory of relativity and could theoretically exist, though they have not yet been detected. This is likely because they closely mimic the observed properties of black holes. Physicists suggest that supermassive black holes at the centers of galaxies may be wormholes. The light emitted by the black hole’s accretion disk (where matter falls into the black hole) may be the light surrounding the wormhole’s entrance, which precisely mimics the properties of the accretion disk’s light. The physicists intend to continue their research to find more evidence that some black holes may be wormholes. The post Galactic Gateways?
