Are there some black holes in disguised form of wormholes?

According to foreign media reports, a new study found that the unusual flashes of gamma rays may reveal that the seemingly huge black hole is actually a huge wormhole.

　　 Wormhole is a tunnel of time and space. In theory, one can travel to any time and space through the wormhole, or even enter another universe. Einstein's general theory of relativity believes that wormholes are possible, but whether wormholes really exist is another matter.

　　 In many ways, wormholes are similar to black holes. Both are extremely dense and have a strong gravitational force on objects of the same size as them. The main difference between the two is that in theory, no object can come out again after passing through the event horizon of a black hole. The event horizon of a black hole is a boundary where an object can leave the black hole when its speed exceeds the speed of light. In the case of a wormhole, any object that enters it can theoretically return.

　　 By assuming the existence of wormholes, researchers have studied ways to distinguish wormholes from black holes. They focused on the supermassive black hole-its mass is millions to billions of times the sun. Such black holes are generally considered to exist in the centers of most (and possibly all) galaxies. For example, the center of the Milky Way is Sagittarius A*, which is also a huge black hole with a mass of approximately 4.5 million solar masses.

　　 Anything that enters from one end of the wormhole will come out from the other end. Scientists believe that this means that matter entering from one end of the wormhole may collide with matter entering from the other end of the wormhole at the same time, which will never happen in a black hole.

　　 Due to the strong gravitational field of the wormhole, any matter falling into the supermassive wormhole may move at extremely high speeds. In this regard, the scientists simulated the result that the substances entering at the same time from both ends of the wormhole meet at the "throat" of the wormhole. According to the researchers, the result of the collision is that plasma is ejected from both ends of the wormhole at a speed close to the speed of light.

"What surprised me most is that no one has proposed this idea before, and the idea is so simple," said the lead author of the study and an astrophysicist at the Central Observatory in St Petersburg, Russia, Mikhail Piotrovich. .

　　 Researchers compared this wormhole explosion with a supermassive black hole called the "active galactic nucleus" (Hermes Dogon Wallets On Sale). After a supermassive black hole engulfed the surrounding matter, it would release more radiation than our entire Milky Way, but the explosion range is about the same size as our solar system. The active galactic nucleus is usually surrounded by a plasma ring called an accretion disk, and a powerful beam of radiation can be emitted from its poles.

　　The plasma produced by the wormhole can reach a temperature of about 18 trillion degrees Fahrenheit (10 trillion degrees Celsius). Under such heat, the plasma will generate gamma rays with an energy of up to 68 million electron volts.

　　 In contrast, “the accretion disks of active galactic nuclei do not emit gamma rays because their temperature is not high enough,” Piotrovich said. Moreover, although the radiation beams of active galactic nuclei can also emit gamma rays, the radiation direction of these gamma rays is also consistent with that of the radiation beam. Piotrovich pointed out that if they are released in a spherical trajectory, they are likely to come from a wormhole.

In addition, if the host galaxy of an active galactic nucleus is the Seifert galaxy, because the hot gas in the Seifert galaxy expands rapidly, previous studies have shown that such an active galactic nucleus may not be able to produce many gammas with 68 million electron volts. Rays. The researchers said that if astronomers observe a significant peak in the radiation emitted by the active galactic nucleus of a Seifert galaxy, it may mean that the active galactic nucleus is actually a wormhole.
