A new puzzling research shows that the rate of expansion in the universe varies by region

Scientists conducted a new study that shows that the rate of expansion of the universe differs markedly when neighboring sites are compared to distant locations.

New research has shown that the rate of expansion of the universe is even more new data show that there is a gap in this rate when neighboring localities are compared to those that are further away.

Scientists stress this "tension" and suggest that they might need to go back to the drawing board and rethink the physics behind the universe, which also means dark energy and dark matter, like reported Space .

Looking at new measurements of nearby locations in the universe with the Gaia Space Telescope and the Hubble Space Telescope, expansion was determined at approximately 45.6 miles per second per megaparsec. However, in the very distant universe, this rate of expansion has been a little slower at 41.6 miles per second per megaparsec, according to data from the Planck telescope.

In fact, while scientists continue to deepen measurements like them, they found that the gap between the rate of expansion in different regions of the universe continues to grow and its # 39; expanding.

Adam Riess, professor of physics and astronomy at Johns Hopkins University, described how the new data The scientists remained completely perplexed and were looking for an explanation.

"At this point, it is clear that this is not just a gross mistake in any given measure.It is as if you had predicted the size of a child from a child. 39, a growth chart, and then found the adult, he or she has become far beyond the prediction.We are very perplexed. "

– SPACE.com (@ SPACEdotcom) July 13, 2018 [19659010] The expansion of the universe is something that has accelerated tremendously as it continues to grow, for reasons that are not yet fully understood. While some scientists suggest that this accelerated rate of expansion can be linked in some way to dark energy and dark matter, others believe that it is also possible that there is a subatomic particle that has not been discovered that could be at the root of

To take the last measurements studied, the Hubble Space Telescope and the Gaia Space Telescope observed Cepheid variables , which are a specific type of star that can be observed in a very predictable way. In this way, scientists can look at the brightness of the star and accurately measure their distance in the universe relative to the Earth. With these data, scientists can then extrapolate the rate of expansion of the universe through their measurements.

While Planck's data badyzed how the Universe was able to end up 360,000 years after its formation, representatives of the Space Telescope Science Institute (STScI) note that its predictions seem very different from the most recent measurements that have been taken of the rate of expansion of the nearby universe.

"These measurements, again evaluated, allow scientists to predict how the primitive universe would probably have evolved – the rate of expansion that we can measure today." However, these predictions do not seem to match the new measures of our near contemporary universe. "

The new study showing how the rate of expansion of the universe was found to vary in different places was published in The Astrophysical Journal .
