Astronomers have discovered what they claim to be a new proof that Earth and our Milky Way galaxy are suspended in a gigantic void – that is distorting our cosmos observations.
Big Bang echoes revealed this Wednesday suggest that the Milky Way is attached to a gigantic cosmic emptiness.
In the royal astronomical society’s National Astronomy Meeting in Durham, England, astronomers claim to have found evidence that supports a controversial observation that our galaxy resides in unusually scarce region of space.
The radical proposal, made through the analysis of Big Bang echoes, suggests that our galaxy may be floating in a region of 2 billion light years which is 20% less dense than average.
If the results are confirmed, they can help astronomers discover the true age of our universe and offer a solution to one of the most difficult puzzles of cosmology – the discrepancy, known as Hubble’s tension, according to which the distant universe has expanded more slowly in the past than the close universe today.
As it refers, findings would also lead to a great reformulation of existing cosmological models.
In, the main author of the study, Indranil Banikfrom the University of Portsmouth, in the United Kingdom, theorizes that “our galaxy is near the center of a large local void.”
“This would make the matter pulled by gravity to the abroad of greater density of the emptiness, leading to the emptiness was emptied over time. And that would cause local expansion inside the void to be faster than in denser and distant regions of the cosmos, ”he added.
Fill the Void
The notion that our part of the universe could be less dense than others took shape for the first time in the 1990s, when researchers found fewer galaxies in our local universe than they expected, compared to the surrounding universe.
Later investigations confirmed these observations, indicating that our galaxy may be in the center of a region known as the local hole or KBC Emptyname given by the initials of the study’s astronomers.
However, some astronomers question whether the apparently little dense space may be filled with objects that do not emit light.
Now, to better investigate the evidence, Banik and his colleagues have collected 20 years of data from the nearby barely oscillation observations (BAOS) – pressure waves created during the Big Bang that have frozen and expanded throughout the universe, governing the distribution of the galaxies we see today.
According to the BAO of the researchers measurements, it is 100 times more likely that we live in a cosmic void than in a region of average density.
Modern astronomy has consistently revealed that our personal view of the cosmos is not exceptional. If we actually live in the midst of the emptiness, We can be even more unique in our isolation than what was thought.
