[SAPOD]Today’s “space image”. We introduce characteristic images introduced by sorae in the past, attractive images released by space agencies around the world, and images sent by space astronomy fans and experts. (There is a link to the original article at the end of the article)

sorae – Imaging of “topological stars” Non-black black hole-like objects
This is the article that sorae introduced on May 8, 2023.Appearance of phase defects (topological stars)]is a simulation image.
A research team, including Pierre Heidmann of Johns Hopkins University,Alternatives to black holesOne of the “Phase defect (topological soliton)We investigated the theoretical content and appearance of the celestial body. The phase defect is “topological starIt is one of the types of celestial bodies called
A phase defect is thought to be a small object with a strong gravitational pull that is at first glance indistinguishable from a black hole. However, unlike black holes, phase defects do not have a central singularity. This is because the space-time, which has been rolled up in a very complicated manner, prevents it from collapsing into a single point with no size. On the other hand, since the “winding up of space-time” also appears on the surface, it is thought to affect the appearance of phase defects.
