According to foreign media reports, a new study has found that the unusual flash of gamma rays may reveal that seemingly huge black holes are actually giant wormholes. Wormholes are tunnels of space and time. Theoretically, wormholes can travel to any time and space, or even enter another universe. According to Einstein’s general theory of relativity, wormholes are possible, but whether wormholes really exist is another matter. In many ways, wormholes and black holes are similar. Both are extremely dense and have a strong gravitational pull on objects about their size. The main difference between the two is that, theoretically, 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 wormholes, any object that enters it can theoretically return. < / P > < p > by assuming that wormholes exist, researchers have developed ways to distinguish wormholes from black holes. They focused on supermassive black holes – millions to billions of times the mass of the sun. Such black holes are generally thought to exist in the centers of most (and possibly all) galaxies. For example, at the center of the galaxy is Sagittarius A *, which is also a huge black hole with a mass of about 4.5 million solar masses. < / P > < p > anything that enters from one end of the wormhole will come out from the other. Scientists believe that this means that material entering from one end of the wormhole may collide with material entering from the other end of the wormhole at the same time, which never happens in a black hole. < / P > < p > due to the strong gravitational field of the wormhole, any material falling into the super mass wormhole may move at a very high speed. In response, scientists simulated the encounter of material entering the wormhole from both ends at the “throat” of the wormhole. As a result of the collision, the researchers said, plasma was ejected from both ends of the wormhole at a speed close to the speed of light. < / P > < p > “what surprised me most was that no one had put forward this idea before, and the idea was so simple,” said Mikhail piotrovitch, an astrophysicist at the central observatory in St. Petersburg, Russia, the lead author of the study. < / P > < p > the researchers compared the explosion of this wormhole with that of a supermassive black hole called an active galactic nucleus (AGN). After swallowing the surrounding material, supermassive black holes emit more radiation than our entire galaxy, but the explosion is about the size of our solar system. Active galactic nuclei (AGNs) are usually surrounded by plasma rings called accretion disks and emit powerful radiation beams from their poles. The plasma produced by wormholes can reach about 18 trillion degrees Fahrenheit (10 trillion degrees Celsius). In this heat, the plasma will produce gamma rays with an energy of 68 million electron volts. In contrast, “AGN accretion disks do not emit gamma rays because they are not hot enough,” piotrovitch said. Moreover, although the radiation beams of AGN can also emit gamma rays, the radiation direction of these gamma rays is consistent with the radiation beams. Piotrovitch points out that if released in a spherical trajectory, they are likely to have come from wormholes. In addition, if the host galaxy of an AGN is the Seyfert galaxy, previous studies have shown that such an AGN may not be able to generate a lot of gamma rays with 68 million electron volts due to the rapid expansion of hot gas in the Seyfert galaxy. If astronomers observe a significant peak of the ray emitted by an AGN in a Seyfert galaxy, it may mean that the AGN is actually a wormhole, the researchers said.
