Scientists believe that the shape of the universe is not what everyone thinks

The authors of a new study have suggested that the universe may actually be in the shape of a giant donut,

regardless of other information. The strange patterns found in the echoes of the Big Bang can be explained by the fact that the universe has a more complex shape.

Astronomers have measured the topology of the universe in several ways. All evidence suggests that it is geometrically flat and has a simple unfolded topology.

But the authors of the study published in the databasearXiv preprint data suggested that past measurements were limited. In particular, observations suggest that the universe wraps around itself in only one dimension. In addition, it does not have a more complex topology. Also, observations of the CMB revealed some strange, inexplicable anomalies - the appearance of large patterns where they should not be.

In a new study, scientists have examinedThe cosmic microwave background is light emitted when the cosmos was only 380,000 years old. It is now more than 42 billion light-years away and is characterized by tiny fluctuations in temperature. Astronomers calculated the predicted size of these fluctuations compared to observations, and they differed. This means that those rays of light that have been coming out in parallel since the beginning of time have changed direction in space-time. And, therefore, the geometry of the universe is curved.

But the same measurements showed that if nottake into account small-scale deviations from galaxies and black holes, the overall geometry of the universe is flat. In fact, a Universe with a complex topology could explain at least some of the CMB anomalies.
