The universe can be a billion years younger than we thought. Scientists are trying to understand why.



We have all lost a sense of time at one point or another, but astronomers are really everywhere. show that they have overestimated the age of the universe with more than a billion years – a surprising realization that forces them to rethink key parts of the scientific history of how we have come from the Big Bang to this day.

Lost time is particularly annoying, because in the universe full of mysteries, its age is seen as one of the few almost certain. By 201

3, the detailed measurements of the cosmic radiation of Planck's European space telescope seem to have given the final answer: 13.8 billion years. It was only to check this number, using independent observations of bright stars in other galaxies.

Then came an unexpected turn of events.

Several teams, including one headed by Nobel Prize-winning Adam Rees from Space, The Baltimore Science Institute decided to make these observations. Instead of confirming Planck's measurements, they began to get a distinctly different result.

"It reached the point where we said," Wait a second, we do not pass this test – we miss the test! "says Rhys, co-author of a new book on the study, to be published in the Astrophysical Journal.

He estimates that his results at a nominal value show a universe of only 12.5 billion to 13 billion years.

The research of star clusters in a neighboring galaxy adds to the evidence that the universe is younger and more expansive than expected Space Telescope Research Institute Public Service Service (NASA, ESA, A. Race STScI / Initially, the general assumption was that Rhys and the rest observe But when their observations continued to appear, the results did not move.Planck's data reanalysis has not shown any problems

If all the numbers are correct then the problem should be deeper "It must lie in our interpretation of these numbers-that is, in our basic models of how the Universe works." The divergence implies that there is something in the cosmological model that we do not understand properly, "says Rhys. What can be something, no one knows.

The Discovery of the Dawn of Time

The current inconsistency traces its origins since 1929, when the astronomer Edwin Hubble discovered that the galaxies flee the Earth in all directions. Even more shocking, Hubble found that the farther the galaxies are, the faster they are separated. This pattern means that they all run away from each other. "The only way this can be true is if space is expanding," says Rhys.

If the idea of ​​an expanding universe seems strange to you, welcome to the club.

"It's still strange to me, too," says Rees, "but that shows all the data, and that predicts our theory." Even Hubble never took the full effect of its own work

The expanding universe, that the universe has a certain age because you can trace the action back to the time when everything in space has been crammed in an extremely dense, hot state: what we call the Big Bang
