An international team of researchers from Spain, the United Kingdom, Germany and France, led by experts from the Center for Physics Studies of the Cosmos of Aragon, in Teruel (Spain) has discovered the first evidence of ordinary matter of the Big Bang , that is, of the one from which stars and galaxies are made but that with current technological advances we were still unable to see or detect.
However, based on the measurements of the Cosmic Microwave Background of the Planck space telescope of the European Space Agency (ESA), whose objective is to verify current theories about the early universe and the origins of cosmic structures and the data from the Sloan Digital Sky Survey , astronomers have managed to find out where a part of that baryonic matter (the matter that makes up everything around us) was hidden, which is neither dark matter nor antimatter.
Analyzing and measuring the small energetic fluctuations in 200,000 galaxies and comparing these results with regions of the universe where none of these accumulations of stars, dust and gas exist, the radiation of the Big Bang itself that transfers a small amount of energy to this ordinary matter, it has been the key to removing that veil that prevented us from detecting this lost matter . The result has been the discovery of large amounts of matter that until now had not been able to identify.
The study has been published in the journal Physical Review Letters.
Some interesting data:
Equation of the universe: baryonic matter + dark matter + dark energy
Ordinary matter represents 4.5% of the total mass of the Universe (that is, planets, stars, galaxies … and a large amount of visible matter not yet discovered by us that would make up more than 70% of that total)
The rest of the universe represents 23% dark matter and 73% dark energy.
