Science and Technology Daily, Beijing, January 9 (internal reporting by Hu Dingkun) The Durham University Joint Research Group and the University of Helsinki, Finland, recently wrote in the International Astronomical Newspaper The Royal Astronomical Society Monthly that the Great Magellanic Cloud (LMC) can be 20 After 100 million years, she ran into the Roman road. Just as pebbles are thrown into a calm lake, this will cause snooping of water, and the earth will throw it from the Roman road during this blow.

Like the moon moon moon and the Roman road is surrounded by a group of satellite galaxies, the Magellan cloud is one of the brightest, about 163,000 light-years away from the Roman road. Before that, astronomers believed that it would take billions of years around the Roman road and perhaps even escape from the Roman road.

Researchers have found that the mass of the large Magellanic cloud is far from expecting, and its orbital energy will rapidly decline with dynamic friction and is likely to collide and merged with the Roman road after 2 billion years. Simulation studies have shown that the impact will be caused by devastating accidents in the Roman Road. A black hole in the Roman road will be active, the volume will increase 10-fold rapidly, and the weight increase will be up to 8 times. Active black holes will release a large amount of high-energy radiation if the gamma rays generated by jets reach the Earth, they will destroy the ozone layer and cause the extinction of a large number of organisms.

However, the researchers also found that the solar system is likely to pull out of the Roman road, into a larger space during the impact, and that the Earth will be saved. Astronomers have announced that the Andromeda galaxy will hit the Roman road for eight billion years, which will accelerate the possible time of the collision between the Roman road and other galaxies over six billion years.

Marius Cowton, the first author of the thesis and postdoctoral work at the Institute of Computational Cosmology at the University of Durham, said that 2 billion years is very long compared to human life, but in the cosmic time period it is very short. Professor Carlos Franck, director of the Institute of Cosmology, emphasized that the universe is constantly evolving with similar collisions of galaxies, and our children and grandchildren will see a spectacular cosmic fireworks displaying extremely bright jets.
