EsaThe mysterious force called Dark Energy, which drives the expansion of the universe, may change in a way that challenges our current understanding of time and space, scientists said.
Some of them believe that they may be about to be about one of the biggest discoveries in astronomy for a generation – one can impose basic rethinking.
This conclusion in the early stage contradicts the current theory that was partially developed by Albert Einstein.
More data is needed to confirm these results, but even some of the most cautious and respectable researchers, such as Professor Lahaf, from College University London, are invaded through escalating evidence.
“It is an exciting moment,” BBC News told BBC.
“We may see a model in our understanding of the universe.”
The discovery of dark energy in 1998 was in itself. Until then the opinion was that after the big explosion, which created the universe, its expansion would slow down under the power of gravity.
But the notes made by the Australian scientists found that He was actually rushing. They had no idea what this was the power of this leadership, so they gave him a name indicating their lack of understanding – dark energy.
DisiAlthough we do not know what dark energy is – it is one of the greatest puzzles in science – astronomers can measure it and whether they change by monitoring the acceleration of galaxies away from each other at different points in the history of the universe.
Several experiments were built to find answers, including the Dark Energy Speaker at the Kit Peak National Observatory near Toxon Arizona. It consists of 5,000 optical fibers, each of which is galaxies of a telescope that is controlled by asthma at a high speed.
Last year, when researchers at Desi found hints that the force practiced by dark energy had changed over time, many scientists believed that it was an edge of the data that would disappear.
Instead, after a year, those heroes grew.
“The guide is stronger than it was,” said Professor Sigdri Nadathor of the University of Portsmouth.
“We have also conducted many additional tests compared to the first year, and they make us confident that the results are not driven by some unknown effect on the data that we did not count,” he said.
“Strange” results
the Data It has not yet passed a threshold described as a discovery, but he led many astronomers, such as astronomer in Scotland, Professor Catherine Heemans, from Edinburgh University, to sit and notice.
“It seems that the dark energy is more strange than we thought,” she told BBC News.
“In 2024, the data was completely new, and no one was completely sure of it, and people believed that more work should be done.
“But now, there is more data, and a lot of scrutiny by the scientific community, so, while there is still an opportunity because” BLIP “may disappear, there is also a possibility that we will get to know a really big discovery.”
EsaSo what causes contrast?
“Nobody knows!” Professor Lahaf admits, fun.
“If this new result is correct, we need to find the mechanism that causes contrast and this may mean a new theory, which makes this very exciting.”
Desi will continue to take more data over the next two years, with plans to measure approximately 50 million galaxies and other bright things, trying to reduce whether their observations are unambiguously correct.
“We are in the field of allowing the universe to tell us how it works, and it may tell us that it is more complicated than we thought,” said André Coso, a post -PhD researcher at the Lawrence Berkeley National Laboratory in California.
More details will be obtained about the nature of the dark energy by the European Space Agency (ESA) Euclid missionThe space telescope that will be achieved beyond Desi and gets more details. It was launched in 2023 and ESA released new photos from the spacecraft today.
Desi’s cooperation includes more than 900 researchers from more than 70 institutions, all over the world, including Durham, Ucl and the University of Portmouth from the United Kingdom.
