A team of Chilean physicists argued that the key to determining whether the universe is unique or whether there are many (multiverse) can be in the light of the cosmos, it is to say that at the Big Bang, the researchers informed Efe.
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 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, we still learn a lot," said Gonzalo Palma, an academic in the Department of Physics of the Faculty of Physical and Mathematical Sciences at the University of Chile, one of the tigadores
"Our best theories suggest that the universe is made up of many" small universes ", or" local universes, "each having its own laws of physics" Gonzalo Palma , University of the Department of Physics, Faculty of Physical and Mathematical Sciences, University of Chile
"Our best theories suggest that the universe is made up of many" small universes ", or" local universes ", each having its own Such a scenario would indicate that what we know today would be only a small bubble of a vast multiverse. "
According to Gonzalo Palma, also a doctorate in Theoretical Physics from Unive In Cambridge, it is known that before the Big Bang, the "universe must have experienced an accelerated phase of expansion 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 use other 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 fuzzy, so it will not be easy to discover them, but the situation could change," he said.
The data badyzed during the research was provided by the European Space Agency's Planck space satellite (ESA) and Xingang Chen, a professor at Dep. Department of Astronomy, Harvard University
