A high-resolution simulation of cosmology and astrophysics revealed the first structures in the Universe. In a new study, scientists noted that in the first trillionths of a second after the Big Bang, gravity was responsible for agglomerating quantum particles, forming dense pieces that weighed between a few grams and 20 kilograms. The initiative was based on the inflation paradigm, a theoretical model dealing with cosmic origins and evolution.
“We are discovering this incredibly complex phase about the beginning of the Universe, a period that is just beginning to be properly understood,” said Richard Easther, a physics professor at the University of Auckland, New Zealand, involved in the study, in an interview. with the Live Science website.
The simulations focused on the final moments of inflation, a period of rapid expansion of matter. The results showed that the initial volume was ten million times that of the formation of shapes in an energy field immediately after the Big Bang, including large-scale phenomena known today, such as black holes.
According to the researchers, it is plausible that this inflation occurred in a short time, since it must have turned into elementary particles in fractions of a second. Due to their high density, their movements and interactions may have caused ripples in the fabric of space-time, called gravitational waves.
In addition, there is a suggestion that the collapse of small structures may have been due to their own weight, which would explain the original black holes. For some scientists, these primitive phenomena may be candidates to explain dark matter, a mysterious substance that represents 85% of the matter in the Universe.
In this context, it is expected that new, longer and more detailed simulations will aid in future experiments to reveal a variety of as yet unknown events.
