Gaia and Hubble tell us how fast the Universe is growing

Recently, we learned that the universe was developing at two different speeds, based on new data collected both by Gaia space observatory belonging to the European Space. Agency, and the Hubble Telescope. These latest discoveries could even suggest a whole new physics, which could provide a better understanding of the universe

New Exciting Implications

Measuring the rate of expansion of the universe n '# 39; is not an easy thing to do. On the basis of the updated precise measurements taken by the two telescopes, it seems that the uncertainty of the new calculations is only 2.2%.

It has already been hypothesized that the tension between the two different rates of expansion could be a sign of the existence of an unknown particle or the interaction force of matter. black.

The value of the Hubble constant has also been refined by Gaia and Hubble. This constant represents the speed at which the universe is developing since the time of the big bang, and it is extremely important to establish the age of the universe. This is, after all, one of the main issues of our time. The most recent value was determined by measuring the distance between galaxies. This is made possible by following the stretching of light between galaxies. Then, the distances were compared to the expansion rate of the space to calculate the value of the Hubble constant. What has been found is that the newly determined values ​​are in conflict with the previous measurements that were taken by the Planck mission of the European Space Agency

The new predictions contradict the earlier measurements

Based on the prediction of Planck. the universe near our time is 41.6 miles per second per megaparsec. Nevertheless, according to the new measures taken by Gaia and Hubble, the rate of expansion is placed at 45.6 miles per second per megaparsec. These results were a surprise to scientists. The researchers plan to continue using Gaia to refine the Hubble constant, in a value of only one percent by 2020.
