The Universe’s Most Precise Measurements Show Something Is Very Wrong

The Universe's Most Precise Measurements Show Something Is Very Wrong

Researchers discovered that the universe is expanding at a completely different rate than previously thought; this is a groundbreaking discovery that could undermine our current understanding of the universe.

Inside new paper published Astrophysical JournalAn international team of researchers studied the light emanating from 1,550 different supernovae to study the composition and expansion rate of the universe – some near our own Milky Way and some in the farthest reaches of the universe, millions of light-years away.

In doing so, their analysis, called Pantheon+, includes some of the most comprehensive measurements ever made.

“With these Pantheon+ results,” said Dillon Brout, co-author and researcher at Harvard’s Center for Astrophysics. said this Harvard Gazette“We are able to place the most precise constraints ever on the dynamics and history of the universe.”

Excitingly, their findings support some relevant existing theories. dark To be importantA mysterious but abundant matter and dark energy that scientists have not yet observed or measured directly, is a hypothetical form of energy that behaves like the opposite of gravity.

Their research suggests that the entire universe is made up of roughly two-thirds dark energy and one-third matter, with the latter mostly made up of dark matter.

“We’ve combed through the data,” Brout continued, “and now we can say with more confidence than ever that the best available theories for dark energy and dark matter are strong, and how the universe has evolved over the ages.”

But at the same time, the study fails to correct one of the biggest inconsistencies in astronomy: the apparent mismatch between previous, locally measured estimates of the Hubble tension, or the rate of expansion of the universe, and the measurement derived from the rate of expansion of the universe. cosmic microwave backgroundelectromagnetic remnants of the earliest known phases of the universe.

While the new research suggests that the universe is expanding at roughly 160,000 miles per hour, previous measurements that took into account the cosmic microwave background concluded that the universe is expanding much more slowly than that.

While Pantheon+ has confirmed the inconsistency, it hasn’t exactly given any answer for it.

“We thought it would be possible to find clues in our dataset for a new solution to these problems,” Brout said. Harvard Gazette“But instead we find that our data excludes many of these options, and that the deep differences are as persistent as ever.”

Researcher “Definitely shows” said Agence France-Press“potentially something is suspect with our understanding of the universe.”

Clearly, Pantheon+ has opened more doors than it has closed. But this is, in a way, scientific process — The research by Brout and his team could lay the groundwork for a number of future discoveries.

“We as scientists are good at not understanding everything,” Brout continued. AFP. “There is a major revolution that is potentially unfolding in our understanding, potentially in our lives.”
