For example,
Revelation divides scientists:
What if our galaxy floated in a huge cosmic vacuum bubble? A gigantic region, two billion light years old in diameter, almost empty. For example, A team of British researchers advances this amazing idea to explain the famous tension de Hubble. Furthermore, This is a persistent disagreement between what we observe today … Furthermore, and what the theory predicts.
For several years, scientists have been trying to measure the speed at which the universe has expanded. However, according revelation divides scientists to the method used, the results do not coincide. Furthermore, This discrepancy disturbs cosmologists. For example, But according to this new hypothesis, he could explain more simply than we imagined.
A gigantic emptiness around the Milky Way could explain why the universe seems to extend faster near us – Revelation divides scientists
According to the researcher Indranil Banikour galaxy would not be in a “banal” area of the universe. For example, On the contrary, it would be nestled in the center of revelation divides scientists a huge videbaptized KBC Void. However, This region, with a diameter of two billion light years, would be about 20 % less dense than the average.
In this type of configuration, the surrounding material is attracted to the outside. However, This phenomenon causes faster local expansion. Consequently, From then on, We might believe that the universe accelerateswhile it is only an illusion linked to our particular location.
Consequently, this idea would explain why the two methods of expansion measurement give divergent results. Not because one is false, but because We measure from a corner of the unrepresentative universe.
Big Bang fossil waves confirm that our region is less dense than the average – Revelation divides scientists
To test this idea, the researchers relied on a tool as fascinating as it is precise: Baryonic acoustic oscillations. These “sound waves” of the Big Bang remained frozen in the matter from the first moments of the universe. Even today, they influence the distribution of galaxies.
By analyzing 20 years of data Coming from these oscillations. the Portsmouth team has reached an astonishing conclusion: it is 100 times more likely that we live in a sub-dense region than in a uniform area. In other words, Our cosmic perception is most likely biased.
In addition, these results are added to another anomaly known since revelation divides scientists the 1990s: Our region contains fewer galaxies What planned. This deficit is observable. He is not only theoretical.
However, some scientists remain skeptical. For them. invisible objects – such as dark matter or neutrinos – could hide in this area and distort the measures. Others recall that The standard model is based on a homogeneous distribution of materialwhat this hypothesis clearly calls into question.
This hypothesis could upset our place in the cosmos. force scientists to review their model
Modern science has always teaches us humility: We are not at the center of the universe. But this theory of cosmic emptiness reverses this perspective. And if, this time, Our position was really exceptional ?
Indeed. living in such a large bubble could distort all of our measures: expansion, density, even the age of revelation divides scientists the universe. It’s not nothing. It would mean that What we take for a universal truth might be a simple local illusion.
To go further. researchers want to confront their model with other hypotheses. They plan to use Cosmic chronometersof the Gravitational flow cartographies and simulations of the evolution of matter. Thus. they hope to determine whether this bubble is very real, or if another phenomenon could better explain the observed differences.
If this hypothesis is confirmed, then Cosmology will have to adapt. It will have to integrate this idea of an uneven, variable, locally disturbed universe. It would be a major change.
What if our universe was not so homogeneous as one imagined it?
This hypothesis, as dizzying as it is, underlines a fundamental principle: Science advances thanks to doubt. What revelation divides scientists we believe stable can, in reality, depend on the place where we look at.
Maybe we live in a huge void. Perhaps everything we observe is already partially distorted. But this void is not a lack. It is a clue. One possibility. An opening.
And if he helps us to understand finally why the universe does not behave as planned. then This void could well become one of the greatest cosmological revelations of the century.
