Recent cosmology The model combines two of the most eccentric ideas in modern physics to explain the nature of dark matter, an invisible substance that makes up about 85 percent of all matter in the universe. To understand, it is necessary to look beyond Big Bang we all know and consider two concepts that rarely overlap: the rotating universe and primordial black holes.
A Different Kind of Multiverse
There are different versions of the “multiverse.” The most popular model—that of the Marvel Cinematic Universe—suggests that there are as many universes as possible and that these versions of reality are compatible. Physics suggests something more quantitative and mathematically stable: the rhythm of space.
In this model, the universe is not born from unity, but expands, contracts, and expands again in an endless cycle. Each “world” is not parallel, but a series – that is, one rises from the ashes of the previous one.
Is it possible for something to survive the end of the world and endure into the next? According to a paper published in Physical Assessment Dyes. The author Enrique Gaztanaga, a research professor at the Institute of Space Sciences in Barcelona, shows that any structure exceeding 90 meters can pass through the final collapse of the world and survive the reentry. These “relics” would not only continue, but could also give rise to the formation of large, inexplicable structures observed in the early stages of the present world. Furthermore, they may be the key to understanding dark matter.
For decades, the main explanation for dark matter was that it was an unknown particle or particle. But after years of experiments without direct detection, physicists have begun to explore alternatives. One of them suggests that dark matter is not an alien particle, but a large number of small black holes that we ignore.
The idea is interesting, but it has a big problem. For black holes to explain dark matter, they would have to have existed since the very beginning of the universe, long before the first stars collapsed. There are indications that these substances may exist, but a convincing physical mechanism to explain their origin is lacking.
A Universe Born Of Black Holes
This is where Gaztanaga’s proposed new model shines. If the cosmic rhythm allowed compact structures to survive the collapse of the past universe, then the present universe would have already been born from pre-existing black holes. They wouldn’t have to be produced by super evolution or well-planned inflationary processes, but they would have been there from the start.
The concept has the ability to solve two riddles at once: the nature of black holes and the nature of dark matter. If this model is correct, dark matter would not be a mystery of the early universe but a legacy of the universe that preceded our universe.
“Much work remains to be done,” Gaztanaga, also a researcher at the Institute of Cosmology and Gravitation at the University of Portsmouth, said in an article in Conversation. “These ideas must be tested against data—from the origin of gravitational waves to observations of galaxies and precision measurements of the microwave background.”
“But the odds are high,” he added. “The universe may not have started overnight, but it may have returned. And the dark structures that make up galaxies today may be remnants of time before the Big Bang.”
