New evidence indicates one of the largest research of the universe to this day that the mysterious dark energy may develop in ways that can change the way astronomers understand the universe.
A Dark energy It is a term used by scientists to describe the energy or power that speeds up the expansion of the universe. But although it represents 70 % of the energy in the universe researchers do not know exactly what dark energy, Mustafa Yahak Bouchki, professor of physics and astronomical physics at the University of Texas in Dallas.
ISHAK-BOSSHAKI is a co-chair of a working group of the spectral tool for dark energy known as Desi. The tool, now in its fourth year, can monitor the sky, monitor the light of 5000 galaxies at the same time. Upon completion of the project next year, the light of light will be about 50 million galaxies.
The cooperation, which includes more than 900 researchers, participated in the latest data for the first three years of notes on March 19. Among the results of its findings are measurements of approximately 15 million galaxies and monsters, some of the brightest things in the universe. ISHAK-POSSHAK helped to lead another analysis of DESI data, indicating that the dark energy-a long time is called the “cosmic constant”, where astronomers believed that it does not change-they act unexpectedly and may weaken over time.
“The discovery of dark energy, about 30 years ago, was the biggest surprise for my scientific life,” said David Winberg, a professor of astronomy at Ohio State University, who contributed to Disi’s analysis in a statement. “These new measurements provide the strongest evidence so far that dark energy is developing, which will be an impressive change in our understanding of how the universe works.”
Scientists say the results make astronomers a step closer to revealing the mysterious nature of dark energy, which may mean that the standard model of how the universe works may also need to be updated.
The dark energy tool in Nicholas U. The “eyes” of the 5000 optical fibers of fibers and its wide research capabilities allow scientists to build one of the largest 3D maps in the universe and track how dark energy affected the universe and formed over the past 11 billion years.
The light of heavenly things like galaxies takes time to reach Earth, which means that Desi can effectively see what the universe is at different times, from one billion years to the present.
“Disi is different from any other machine in terms of its ability to monitor independent things simultaneously,” said John Mustakas, a professor of physics at Siena College and the difficulty of publishing data.
The latest results include data on more than the weakness of the cosmic creatures that were discussed and displayed less than a year ago. These detectors 2024 were the first to suggest how dark energy could develop.
“We are working to let the universe tell us how it works, and the universe may tell us that it is more complicated than we thought,” said André Cio, a post -PhD researcher at the American Energy Laboratory Laboratory Laboratory, who runs Design de Desci Disio in a statement. “It is interesting and gives us more confidence to see that many different evidence lines indicate the same direction.”
Desi can measure what scientists call the scale of baroni vocal fluctuation, or Bao – mainly as events that occurred at the beginning of the universe, which left the criteria for distributing material by the universe. Astronomers are the BAO scale, with the separation of about 480 million light years, such as the standard ruler.
“This separation scale is similar to a truly huge ruler in space, which we can use to measure distances, and we use a mixture of these distances and deviations to red (the speed that things away from us) to measure the expansion of the universe,” said Paul Martini, the coordinator of the analysis and astronomer in Ohio’s government.
Measuring the effect of dark energy throughout the history of the universe shows how this dominant power was.
The researchers began to notice when they merged these notes with other light measurements through the universe, such as explosive stars, and deformed light due to the intensity of distant galaxies and the remaining light of the beginning of the universe, called the cosmic background radiation, DESI data shows that the effect of dark energy may decline over time.
“If this continues, the dark energy will not eventually be the dominant power in the universe,” said EHak Bouchk via email. Therefore, the expansion of the universe will not accelerate and go to a fixed rate, or in some models, may stop and collapse. Of course, these future contracts are very far and will take billions of billions and the years will occur.
Ishak Bouchk said there is insufficient evidence to announce a revolutionary discovery that certainly says that the dark energy is developing and weakening, but this may change in only a few years.
Martini said: “My first big question is whether we will continue to see evidence of the development of dark energy with our measurements improved.” “If we get to the point where the evidence is overwhelming, my following questions will be: How do dark energy develop? What are the most vulnerable physical interpretations?”
The new data group can also help astronomical physicists to better understand how galaxies die Black holes The development and nature of the dark matter. Although the dark matter has not been discovered at all, it is believed to be 85 % of the total issue of the universe.
Scientists participating in cooperation are to improve their measurements using Desi.
“Whatever the nature of the dark energy, it will form the future of our world,” said Michael Levy, director of Disi and national laboratory scientist Lawrence Berkeley. “It is striking that we can look at Paradise with our telescopes and try to answer one of the greatest questions that humanity posed ever.”
Martini said that a new experience called SPC-S5, or stage 5 of the spectral experience can measure more than 10 times more galaxies than Desi to study both dark energy and dark materials.
Martini said: “S5 Specifications will use telescopes in the northern and southern hemisphere for the map of galaxies throughout the sky,” said Martini. “We are also enthusiastic about how to study the Tilescope (Vera) Rubin SUPERNOVAE and provides a new uniform data collection to study the date of expansion (from the universe).”
Jason Rhodes, a monitoring scientist at the NASA’s batch laboratory, said that other spatial notes, such as the Euclidean Space Telescope and the Nancy Grace Space Telescope, scheduled to be held in 2027, will also contribute to the measurements of the most important dark materials and dark energy in the coming years that can help fill the gaps. Rhodes, who is not involved in Disi, is the American scientific pioneer in Euclid and the main researcher of the NASA’s dark energy team to Euclid.
Rhodes, who is considered interesting results, said the data shows light but continuous between the measurements of the first days of the universe and those in the subsequent universe. “This means that the simplest model of dark energy does not allow exactly the primitive universe that we notice is developing into the late universe that we notice,” said Rhodes.
“It seems that the results of Desi (and some other recent results) indicate that the most sophisticated dark energy model is preferred. This is really exciting because it may mean that new unknown physics governs the development of the universe. Desi has given us attractive results that may indicate that the new cosmology model is necessary.”
