The result of the research, which also included scientists from Harvard University, was published this week in the journal Physical Review Letters. It is based on the fact that the Big Bang marks the beginning of the universe and that The Cosmic Radiation Fund (form of electromagnetic radiation discovered in 1965, which completely fills the universe) is reliable.
It's "the oldest light in the universe, a discovery made decades ago, but which we still learn a lot," said Gonzalo Palma, an academic in the Physics Department of the Faculty of Physical Sciences and mathematics of the University of Chile. one of the researchers.
"Our best theories suggest that the universe is composed of many" small universes "or" local universes, "each with its own laws of physics, such a scenario would indicate that what we know today would only be that a small bubble of a vast multiverse, "he said.
According to Gonzalo Palma, also a doctorate in theoretical physics at the University of Cambridge, it is known that before the Big Bang, "the universe had to have experienced an accelerated expansion phase called cosmic inflation ".
At that time, the "cosmos" had to choose "between different paths, for example, whether or not they contained electrons, our universe chose a specific path, but others could borrow from other paths. "he explained.
He added that if you look at the Cosmic Radiation Fund, you can "rebuild the moment when our universe" has decided to "stay as it is today."
This observation may also "allow the possibility of detecting particles never observed before", such as dark matter ", which has also been affected by this" decision "," he said.
For Bruno Scheihing, another researcher, a Master of Science student, physical mention, from the University of Chile, "it could be that there is a hidden signal in the confines of the universe giving important information about its origins ".
Gonzalo Palma sent a "datum" to astronomers: "Our work assumes that we must place the eye in two places: the cosmic rays of the Fund and the large-scale structure of galaxies", which looks like little close to the network. galaxies from the universe.
"The balloon is now in the field of astrophysicists, because they will have to examine the data to get new conclusions and, in doing so, propose and design future observatories that will look for these signals," he said.
According to Scheiling, until the publication of this book "there was no good reason to search for the predicted models, because never before have the calculation to establish their existence been done "
But now, "the big cosmological experiments will be able to fine-tune the data analysis to see if the predicted signals are there or not," he said.
"These signs are very elusive, so it will not be easy to discover them, but in the decades to come, the situation could change," he said.
Another researcher, Spyros Sypass, a postdoctoral researcher at the University of Chile, revealed that the team was developing "new mathematical techniques to perform efficient data analysis, which could help detect these trends."
This, he stressed, will be important for the data collection phase in the experiments that the team has planned for the instruments installed today in the Atacama Desert.
The data analyzed as part of the research was provided by the Planck space satellite of the European Space Agency (ESA). Xingang Chen, professor at the Department of Astronomy at Harvard University, also participated in the conference.
