Dark energy uses Einstein’s theory of universe challenges

The mysterious force called dark energy, which runs the expansion of the universe, can change in a way that challenges our current understanding of time and location, scientists have found.

Some of them believe that they may be on the verge of one of the greatest discoveries in astronomy for a generation – a one that can force a fundamental reconsideration.

It is on obstacles with the discovery of the initial stage on the obstacles with the current theory that was developed in part by Albert Einstein.

More data is required to confirm these results, but even some of the most alert and respected researchers involved in the study, such as Professor Lahav of University College London, are flowing from growing evidence.

“This is a dramatic moment,” he told BBC News.

“We can see a paradigm change in our understanding of the universe.”

The discovery of dark energy in 1998 was shocking in itself. Till then the scene was that after the Big Bang, the one who created the universe, its expansion would slow down under the force of gravity.

But the comments by the US and Australian scientists found that it Was really getting faster. He had no idea what it is, what it is, so he gave it a name which reflects their lack of understanding – dark energy.

Although we do not know what dark energy is – it is one of the greatest mysteries in science – astronomers can measure it and whether it is changing by looking at the acceleration of galaxies away from each other at various points in the history of the universe.

Many experiments were performed to find answers, including the Dark Energy Spectroscopic Instrument (DESI) at the Kit Peak National Observatory near Tuxon Arizona. It contains 5,000 optical fibers, each of which scans galaxies at a roboticly controlled telescope at high speeds.

Last year, when domestic researchers indicated that the forces imposed by dark energy over time, many scientists thought that it was a bluep in the data that would go away.

Instead, a year later, he has increased the blip.

“The evidence is more strong now,” said Prof. Nadathur at Pritsmouth University.

He said, “We have also conducted many additional tests compared to the first year, and they are assuring us that the results are not motivated by some unknown effects in the data that we have not accounted for,” he said.

data The threshold of being described as a discovery has not yet passed, but many astronomers like Scotland’s astronomer Royal, Professor Catherine Hymens of the University of Edinburgh have led to sitting and taking notice.

“Dark energy also looks more strange than our idea,” told BBC News.

“The data was quite new in 2024, no one was sure about it and people thought that more work needed to work.

“But now, there is more data, and a lot of investigation by the scientific community, therefore, while there is still a chance that ‘Blip’ can be overcome, there is also a possibility that we can really edge for a large search.”

So what is the cause of differences?

“No one knows!” Professor Lahv accepted, cheerful.

“If this new result is correct, then we need to find the mechanism that causes variation and it can mean a new principle, which makes it so exciting.”

Desi will continue to take more data over the next two years, with a plan to measure about 50 million galaxies and other bright items, whether their observations are unevenly correct.

“We are in the business of telling the universe how it works, and perhaps it is telling us that it was more complex as we thought it was,” said Andrei Cuseu, a postdotoral researcher at Lawrence Burkeley National Lab in California.

More details on the nature of dark energy will be obtained by the European Space Agency (ESA) Euclid missionA space telescope that will investigate further from desi and get even more expansion. It was launched in 2023 and ESA today released new images from spacecraft.

Desi cooperation includes more than 900 researchers from more than 70 institutes worldwide, including Durham, UCL and Partsmouth University from UK.
