An international team of astrophysicists has re-calculated the age of the Universe and found that she is about 13.8 billion years. Data collected by the telescope the Atacama in Chile, coincide with the Standard model and measurements of the space Observatory Planck.
The age of the Universe – the value of which astrophysics does not have consensus. The standard model and satellite data Planck claimed that she was about 13.8 billion years, but last year, scientists have calculated the motion of galaxies, that it is 2.3 billion years younger. This difference pointed to the fact that you may need a new model, or that a measurement error has crept in, says Science Daily.
Team space telescope Atacama (AST), located in Chile, calculated the age of the Universe, examining the first light – the microwave background radiation, which arose through 380 thousand years after the birth of the Universe – and the answer coincides with observations of an Observatory Planck. About the universe of 13.77 billion years, plus or minus 40 million.
The data obtained allowed to understand the expansion rate of the Universe, which is calculated by the Hubble constant. Calculations of AST show that the Hubble constant is equal to 67,6 km/s per megaparsec. In other words, the object is at a distance of 3.26 million light-years away from us with a speed of 67.6 km / sec.
The model of expansion of the universe after the Big Bang
This result is also almost identical to the measurements made by the team of the Observatory Planck – 67.4 km/s per megaparsec. Thus confirmed the two most important figures associated with the Universe, which lie at the basis of the Standard model.
