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 the most convincing proof of its existence is the Fund for Cosmic Radiation (form of electromagnetic radiation discovered in 1965, which completely fills the universe ).
"The oldest light in the universe, Gonzalo Palma, a researcher in the physics department of the Faculty of Physical and Mathematical Sciences at the University of Chile," one of his researchers explains. 19659003] "Our best theories suggest that the universe is made up of many" small universes "or" local universes ", each with its own laws of physics, such a scenario would indicate that what we know today is emos would be that a small bubble of a vast multiverse. "
According to Gonzalo Palma, also a doctorate in theoretical physics from the University of Cambridge, it is known that before the Big Bang," the universe had to experience a phase of expansion accelerated. called cosmic inflation. "
At that time, the" cosmos "had to" choose "between different paths, for example to contain electrons or not.Our universe chose a specific path, but others could borrow from others ways, "he explained.
He added that if you look at the cosmic radiation fund, you can "rebuild the moment when our universe" has decided to "become what it looks like today".
Such an observation may also "allow the detection of previously unobserved particles", such as dark matter, "which was also affected by this" decision "," he said.
For Bruno Scheihing, another of the researchers, a student in the Magister in Science, physical mention of the University of Chile, "it could be that there is a hidden signal in the confines of the universe providing important information about its origins "
Gonzalo Palma sent a" datum "to Astronomers:" Our work badumes that we must place the eye in two places: the cosmic radiation of the Fund and the large-scale structure of galaxies ", which looks like a network of galaxies in the universe.
"Now the ball is in the astrophysicists' camp, because they will have to look at the data to get new conclusions and, in so doing, 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 valid reason to search the predicted models, because never before had the calculation been made to establish their existence"
But, now, "big cosmological experiments can refine their data badysis to see if the expected signals are there or not," he said.
"These signals are very vague, so it will not be easy to discover them, but the situation could change," he said.
Another researcher, Spyros Sypbad, a postdoctoral researcher at the University of Chile, revealed that his team was developing "new mathematical techniques to perform badyzes". These are effective data that could help detect these patterns. "
This, he stressed, will be important for the data collection phase as part of the experiments that the team has planned for the instruments installed today in the Atacama Desert. [19659002] The data badyzed in the research was provided by the Space Planck spacecraft of the European Space Agency (ESA) and by Xingang Chen, professor at the Department of Astronomy at Harvard University. , also participated.
