Are we more lonely than we thought?
Enter the Space
For nearly a century, astronomers have been using the Hubble-Lemaitre constant to explain the accelerating expansion of the universe, a key piece of the puzzle that supports the Big Bang theory.
Simply put, the idea is that the speed at which galaxies move away from each other is proportional to the distance between them.
But it has been shown by real observations serious accident, throwing scientists for a loop. This “Hubble tension” has inspired many researchers to make systematic solutions, but so far nothing has satisfied the general scientific community.
Now, researchers from the University of Bonn in Germany and St Andrews in Scotland say they have found a new smart solution.
Their new theory is based on recent data suggesting that our sun is in a region where matter is very small compared to other corners of the known universe, like a “air bubble in a cake,” according to a media coverage – this is a huge space with more dense matter than anywhere else in the universe.
Hubble Bubble
The researchers came to their conclusion by studying the speed of supernovas that are very close to Earth. By calculating their speed, the team arrived at a very different value for the Hubble-Lemaitre constant.
“This is why it seems that the universe is expanding faster in our view – that is, up to a distance of about three billion light years – than its entirety,” explained a the astrophysicist and University of Bonn professor Pavel Kroupa, author of a new paper published in the journal Monthly Bulletin of the Royal Astronomical Societyin the statement.
The result may help explain why astronomers recently noticed a local “underneath the thickness” in our region of space.
“That’s why they left us sooner than expected,” added the University of St. Andrews researcher and author Indranil Banik.
Since the current standard model does not explain these “bubbles,” the researchers suggest that we should re-examine some of the basic rules that date back more than 100 years.
“The classical model is based on a theory of the nature of gravity given by Albert Einstein,” said Kroupa. “However, the forces of gravity may behave differently than Einstein expected.”
As a result, the team has come to support the “new Newtonian dynamics,” which was first proposed by the Israeli physicist Mordehai Milgrom in 1982.
In theory, the idea could completely destroy the Hubble chaos. But it needs to weather a storm of preliminary scientific research.
