The universe began to grow like crazy. It’s all because of black holes
The ever-growing Universe has long been the object of interest of many researchers. Especially since its “recent” changes indicate a significant acceleration, which contradicts the long-term trend of space development. Perhaps we know why this is happening.

According to the current theory about the creation of the world, immediately after the Big Bang, the Universe immediately grew to enormous sizes and then its expansion rate decreased rapidly. However, quite recently (at least from the perspective of the Universe), i.e. 5 billion years ago, changes accelerated again. According to the latest research, black matter and black holes are behind this.
The equation finally fits
If black holes contain dark energy, they can merge and grow as the universe expands, causing it to accelerate
– says astrophysicist Kevin Croker from Arizona State University.
The calculations carried out by researchers, quoted by sciencealert.com, suggest that whatever is responsible for the accelerated expansion of the known universe accounts for about 70 percent of the distribution of matter and energy in the universe. At the same time, physicist Gregory Tarlé from the University of Michigan, who deals with this topic, points out that gravity as strong as at the beginning of the Universe is present in the center of black holes.
According to a concept proposed last year, the extreme distortions of space associated with black holes are related or coupled to the expansion of the Universe. As the universe grows, black holes also grow, and as black holes grow, the universe also grows. New research has focused on the connection between black holes and dark energy. Using the Dark Energy Spectroscopic Instrument, it was possible to check the rate of formation of black holes as a result of the collapse of the cores of massive stars at the end of their lives. Combined with their calculations, the researchers showed that when new black holes were created, the amount of dark energy in the Universe increased accordingly.
Importantly, the new research explains what happened to ordinary matter that should be in the Universe. At the same time, according to the determined rate of black hole formation, the dark energy conversion rate was exactly what was missing by researchers “on the other side of the equation.”
“Fundamentally, whether black holes are dark energy, connected to the universe they inhabit, is no longer just a theoretical question.” – says Tarlé, quoted by sciencealert.com. “It’s an experimental thing right now.”
