At a Congress Center of Cancún, in Mexico, last December, Seshadri Nadatur presented the confidential growth table of the universe. Sitting by the audience, hundreds of his scientists were processed in silence to find out that the cosmic chronicle had needed innovations. “It’s the most exciting thing that happened in cosmology in 25 years,” says Nadatur, the cosmologist of Portsmouth of England Portsmouth.
For almost three decades, astronomers believe that the universe is expanding faster and faster and accelerating that growth is constantly driven by a mysterious force called “dark energy”. Last April survey of energy spectroscopic instrument spectroscopic (desi) Published tips he Dark energy may not be as steady as assumeAdding a pile of concerns that threaten the standard cosmology model. Today, Nadatur and his collaborators have publicly known the results of the American Physion Society to validate the summit of global physics and papers of the American Paper.
After almost tripling the collection of coordinated coordinates researchers, still the cosmic expansion rate events, finally, he finally throws a little light on dark energy.

The evidence still eliminates a physicist reference for a “discovery”, experts said that the new result spreads the standard model. The meaning of a evolved energy of dark energy is almost certainly, it would lead to the basics of physics to unlock the true history and fate of our universe.
“It’s like knocking on a golden waiting,” he says Adam RiessWho shared the 2011 Nobel Prize in Physics Discovery of dark energy And it wasn’t involved in new jobs. Assuming that the result is maintained, “This is an investment that says, it will still be paid for more than learning.”
Cosmic warping
For a century scientists began to realize that the universe is spreading from the outside now that they call Big Bang, the space and time to explode. In the late 1990s, scientists intended to measure how they slow the growth of the universe, to realize that it does not slow down at all. Analysis of Supernova, Riess Group and another independent group of explosions called explosion in 1998 compared to the farther objects, the faster they are returning. In other words, the space is accelerating outside.
Since then, scientists have been in the dark, hence the name of the “Energy” name “. To build a standard cosmology model, the theorists who taste the” cosmological “constant” are “constant” value. Even though Physicists do not understand the origin From this number, their best intention has been the constant energy that throws outside the vacuum of space.
Today, the canonical story of the cosmic evolution describes the inhabitants of the dark energy and the invisible matter “. This standard” model shows a “successful” universe, 95 percent of the model of the model, says Kevork Abazaia, University of California Astrophysician, irvine. “But it’s broken.” Series of conflicting measurements Expansion rate and rigor Cosmos has thrown into cosmology cosmology.
As a result, cosmologists have measured the rate that spreads nothingness, with greater accuracy. The acceleration was firmly demonstrated until they started looking at the sound.
Frozen rumors in space
Soon after the Big Bang, the universe was flying free particles and the surrounding light, creating pressure waves around, as you would get a rock to ponds. After about 380,000 years, everything was cooled to form the atoms, without constantly blowing to other particles that can be freely spilled light (this light is the cosmic radiation of the microwave we can still see today). Suddenly, the primordial pond froze. These waves, known as baryonic acoustic oscillations, to offer galaxies to the galaxies to offer astronomers.

Located in the mountains of Arizona in the south Quinlan, the desire is designed to receive frozen sound waves. 5,000 robotic robotic robotic weapons are explained by catching more than 200,000 night. Then it throws light to a spectrum, revealing the relative age of different sets of galaxies. In years of light over nine million objects, desi detects matter that lights the light from the supermassive black holes in the bright glow in the background. In each slice of cosmic history, the team seeks traces of ripening when distributing matters. Finally, overlapping the measurements of the cosmic background of cosmic microwave and various supernova surveys, researchers can rebuild the three-dimensional map of the universe in the last 11 trillion years.
Last April, 900 members released his first year’s first year study, which showed that the cosmic rate was not matched with the standard model. However, experts had certainly had a signal from a new brand of experiment with limited signals. In this circle, desi has determined almost 15 million galaxies in more than 24,000 exposures, some of which are suspected, suspicious, accidentally crushed the keyboard of the resident telescope cat.
To avoid unconscious interpreters, researchers clearly gave the actual locations of the galaxies, such as their analysis to reveal their true cosmology while they were still working. After months of learning, hundreds of discologators came together to “unlock” Cancún’s results.
A few days before revealing, few selected researchers were quietly exchanged in real measurements and take the plots slowly. Urendert Andrade, a doctoral researcher at the University of Michigan, spent his poker face in the next day and avoid the tries of colleagues to turn on his response. “It’s really magical, you’re one of the few people in the world who knows this,” he said.
When Nadator clicked through his presentation, the message was clear: deviation was not empty. Only cracks of the standard model spread. “Something needs to break somewhere,” says Desi Collalator Claire Lamman, a graduate student at the Astrophysic center | Harvard & Smithsonian.
On their own, the new observation desire shows light but statistically insignificant to evolve dark energy. But when Supernova is combined with other experimental experiments and some of the backgrounds of the microwave, it is clear that it is approximately 99.997 percent. Specify, whatever these data sets, the results are indicated in the same direction. “You can remove a stool leg, and still stops,” Resses says. “It exceeds the Sniff test that I have a very serious (taking) result.”
Rewrite physics
The analysis suggests that dark energy transforms over time today seems to be the announcement of Einstein and the universe is stronger in the beginning of the universe. This progression has the consequences of the final destination of the universe: the dark energy that is too strong could end up all the atoms, and all too weak can attract everything inward.
Aside from the fate, the changing nature of dark energy would now cause deep problems for basic physics. An acceleration rather than described cosmological is reminiscent of what cosmologists call “Phantom Energy”. The density over time is growing.
Assuming the results, this incongence could arouse the era of “chaos cosmology”, Abazajian, recently showed the previous desire results that published the role of the striker preferred the variable dark energy. Consolidation, suggests, to discover completely basic new strength or realize that our universe has more than four dimensions. “No matter what, we are finding new physics here,” Abazajian said. “There is nothing in the standard physics that allow evolutionary dark energy.”
The results directly solve the stresses in cosmology (on the universe and smoothing), researchers could point to new expectations to a stronger model. In the coming years, experiments made with euclid satellite and Vera C. Rubin observatories with additional pointers.
The researchers already begin to desi data from Clues with me. The Riess is intrigued why an evolved dark energy announced Einstein around the value of the cosmological constant. “It’s like an Easter egg, something hidden,” he said.
For many members of Desi, new results bring a feeling of relief. Alexie Leuthaud, Alexie Leuthaud, University of California, Santa Cruz discussed whether cosmologists discussed whether or not they discussed. The experiments of cosmology measured only a cosmological constant with greater accuracy. “It felt for many people that we were chasing these decimals,” he explained. “We are at least somewhere elsewhere.”
The meaning is formed differently for junior researchers. Lamman has warned that since he was able to read, cosmology textbooks have not changed. “This field has always been the same, and I took it to take it,” he said. “I don’t think we’ve ever penetrated that we can find something new.”
After unlocked, some dozen of Lamman and his colleagues went to the beach. Floating in the ocean, he stared at the stars of the stars and shouted to heaven, “we know your secret!”
