According to the latest research from American science, it is possible that the age of the universe is 12.6 billion years, and not 13.8 billion years as assumed. To obtain this result, scientists at the University of Oregon (USA) relied on modern and more precise calculation methods.
Specifically, determining the age of the universe is based on measurements of the distance to the oldest stars, observations of galactic behavior, and the rate of expansion of the universe. Using this hypothesis, we can be traced back to the origin of the universe: the Big Bang. Then the quantity that is of fundamental importance in determining the age of the universe is the Hubble constant. This constant indicates how fast the universe is expanding (in 1929, astronomer Edwin Hubble (USA) was the first to calculate the rate of cosmic expansion).
Therefore, with different assumptions, scientists get different results, as a result, the age of the universe varies from 12 billion to 14.5 billion years.
“It is very difficult to accurately determine the distances in the universe, because the distances between galaxies are extremely large and the objects at these distances are very fuzzy, difficult to observe and difficult to observe. Alignment” – said the scientist Jim Schombert of the University of Oregon. New computational techniques for the Hubble constant, and with it the rate of expansion and age of the universe, are based on observations of microwave background radiation – the rest of the Big Bang.
In addition, scientists at the University of Oregon also use a different method – they take advantage of the distance between Earth and 50 galaxies, precisely determined by the telescope, including the Spitzer Space Telescope. by NASA. They used the collected data to measure distances to the next 95 galaxies. In this way, say the scientists, they more precisely determined the Hubble constant and the age of the universe. The model needed to determine the cosmic age has so far been formed using calculations based on observations from 2013 by NASA’s Wilkinson Microwave Anisotropy Probe (Wilkinson Microwave Anisotropy Probe).
As a result, these observations show that the age of the universe is 13.77 billion years and so far this is a correctly accepted value. Not so long ago (July 2020), this value was also confirmed by the calculations of experts from Stony Brook University (USA).
Meanwhile, based on the new calculations, scientists at the University of Oregon have confirmed that the age of the universe is 12.6 years old. The researchers said the difference in determining the age of the universe shows that we still don’t fully understand the universe.
