Space string

Space stringAn unknown object — a “cosmic string” – has been discovered near the milky Way’s supermassive black hole. This cosmic thread will revolutionize our understanding of gravity, space-time, and the Universe itself.

The center of our Galaxy has been intensively studied for many years, but it still holds surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole has become a discovery that teases the imagination of astronomers. “A mystery that became part of the thrill. Science has stumbled upon a mystery that is not easy to solve,” said Jun — Hui Zhao of the Harvard-Smithsonian center for astrophysics in Cambridge, Massachusetts. “While we don’t have an answer yet, the path to finding it is fascinating.”

In 2016, Farhad Youssef-Zadeh of northwestern University reported the discovery of an unusual luminous filament near the center of the milky way galaxy using a very large NSL Karl j matrix. Yansky (VLA). The thread is about 2.3 light-years long and curves around and towards a supermassive black hole called Sagittarius A * (Sgr A *), located at the center of the Galaxy.
Another team of astronomers, using an innovative technique to produce the highest quality image, obtained a vision of a curved object from this.

“Thanks to improved imaging, we can now follow this thread much closer to the Galaxy’s Central black hole, and it is now close enough to indicate to us that it should occur there,” said mark Morris of the University of California, Los Angeles. “However, we have a lot of work to do to find out what the true nature of this thread is.”
The researchers looked at three main filaments. First, they explain that high-speed particles are ejected from a supermassive black hole. A rotating black hole combined with a spiral of gas can create a rotating vertical tower of magnetic field that approaches or even permeates the event horizon, the point of no return for falling matter. Inside this tower, the particles will accelerate and produce radio emission as they spiral around magnetic field lines and flow away from the black hole.

The second, more fantastic version is that cosmic filaments are long, extremely thin objects that carry mass and electric currents. Previously, theorists predicted that cosmic strings, if they exist, will migrate to the centers of galaxies. If the string moves close enough to the center of the black hole, it can be captured by it when part of the string crosses the event horizon.
The latter option assumes that the position and direction of the filament coinciding with the black hole are just random superpositions, and there is no real connection between them. This implies similarity to dozens of other known fibers found further from the center of the Galaxy. However, this coincidence is unlikely to happen by accident.
Each of the scenarios under investigation will provide intrigue if proven. For example, if the thread is caused by the emission of Sgr a * particles, this will give important information about the magnetic field in this particular medium, showing that it is smooth and ordered, rather than chaotic.

The second option, the cosmic string, will provide the first evidence of a highly speculative idea with profound implications for understanding gravity, space-time, and the Universe itself.
Evidence for the idea that particles are magnetically thrown away from a black hole would be the observation that particles further away from Sgr A * are less energetic than those close to Them. Testing the idea of a cosmic string will rely on the theorists ‘ prediction that the string must move at a high fraction of the speed of light. Follow-up observations with VLA should be able to detect the corresponding shift in the filament position.

Even if the thread is not physically connected to Sgr A *, the bend in the shape of this thread is still unusual. The bend coincides and can be caused by a shock wave similar to a sonic boom, where the blast wave from an exploding star collides with powerful winds blowing from the massive stars surrounding the Central black hole.
“We will continue hunting until we have a clear explanation for this object,” said co — author Miller Goss of the National radio astronomy Observatory in Socorro, new Mexico. “And we strive to create even better, more revealing images.”
