According to a new study, millions of galaxies that are about to form have been unable to continue to develop after being exposed to the terrible heat from the first stars and black holes formed in the early universe. Our galaxy has survived because it is immersed in a large cluster of dark matter filled with gas inside.
The research results presented at the international conference held on July 1 were also the main content of the new ICC film about the evolution of the galaxy to be presented to the Royal Society here.
The researchers say that the early galaxy, which immediately began forming stars, held on to the coarse gases from which later stars would be formed. Otherwise, this raw gas will be evaporated under the influence of high temperatures radiating from the universe's heat about half a billion years after the Big Bang.
According to scientists, including a group of experts from the University of Tsukuba in Japan, tiny galaxies inside the dark matter clusters were blown up by the heat flow of 20,000-100,000 degrees Celsius.
Dark matter is thought to make up 85% of objects in the universe, and is one of the building blocks of galaxies.
With the use of computer simulations conducted by the international Virgo Consortium team (led by Durham University), scientists learned why galaxies, such as galaxies For example, there are fewer galaxies and companion satellites.
Astronomers have discovered a few dozen small satellites around the galaxy containing Earth, but the simulations reveal that hundreds of thousands of dark matter clusters are orbiting our galaxy.
Scientists say that heat emitted from newly formed black holes and stars will be returned to dark matter and cannot support the development of the surrounding satellite star system.
The findings were presented at a conference on space held at the University of Portsmouth's Gravity and Space Research Institute on Wednesday, July 1. The project was funded by the Technology Council. and Science (STFC) and Japan Science Promotion Association.
Simulations will also be included in the new science film - entitled The Origin of the Universe - a film that combines breakthrough simulations with observations of galaxies to track the evolution of heaven. It contains Earth through the universe's 13 billion year history.
Professor Carlos Frenk, director of the Institute of Space Computing at Durham University, said: 'Whether our standard model of space simulation is of practical value depends on satisfactory answers to the question why these Our galaxy, like our galaxy, has so few companion objects. "
"Simulations show that hundreds of thousands of dark matter clusters are orbiting the galaxy that contains Earth, but they do not form new galaxies."
'We can prove that these potential galaxies have almost no chance of winning the extreme heat coming from black holes and the first stars forming in it.'
'The amount of heat vaporizes the gases from dark matter clusters, making them return to their original state without gas. Only a few clusters of material pioneered in star formation, even before the universe melted to form stars ".
According to scientists, given the natural explanation of the origins of galaxies, the simulations above support the idea that dark, cold materials are the best candidate for pumpkin material. Bile forms most of our universe.
Now, the results depend on experimental physicists, or they directly find these dark matter, or they produce it through particle accelerators, such as the Research Council's Large Hadron Collider. Save the European Nuclear CERN.
Professor Frenk added: 'Identifying dark matter is not only one of the biggest problems of science today, but also the key to understanding the formation of galaxies.'
Dr. Takashi Okamoto from Tsukuba University said: 'This is just the beginning of trying to create real galaxies on computers, but the results we have achieved are very encouraging.'
