31 minutes astronomy: why our universe exist? ago
In a laboratory nestled above the fog of southern Dakota forests, scientists seek the answer to one of the greatest questions in science: why is our universe exist?
They are engaged in a response race with another team of Japanese scientists, who are several years in advance.
The current theory on the origin of the universe cannot explain the existence of the planets. Consequently, the stars and the galaxies that we see around us. However, The two teams build detectors who study a subatomic particle called Neutrino in the hope of finding answers.
The international collaboration led by the United States hopes that the response is in the depths of the soil. Meanwhile, as part of the aptly named Deep Underground Neutrino Experiment (Dune).

Scientists will go 1,500 meters deep in three large underground caves. In addition, The scale is such that the construction teams and their bulldozers seem to be small plastic toys in comparison.
The scientific director of this installation, Dr. However, Jaret Heise, describes these giant caves as “cathedrals of astronomy: why our universe exist? science”.
Dr. Consequently, Heise has participated for almost ten years in the construction of these caves at the Sanford Underground Research Facility (surfing). They isolate from the noise and radiation from the outside world. Today, Dune is ready to take the next step.
“We are about to build the detector that will change our understanding of the universe with instruments that will be deployed by a collaboration of more than 1. 400 scientists from 35 countries which are impatient to answer the question of why we exist,” he said.
During the creation of the universe. two types of particles were created: the material – which are the stars, the planets and everything around us – and, in equal quantities, the antimatter, the exact opposite of the material.
Theoretically, these two astronomy: why our universe exist? types of particles should have canceled each other, leaving nothing more than a great explosion of energy. And yet, we are there, as a matter.
Scientists believe that the answer to the question of why the material exists -. astronomy: why our universe exist? why we exist – lies in the study of a particle called Neutrino and its opposite antimatter, anti -Neutrino.
They will send beams of these two types of particles from the depths of the subsoil of Illinois to the detectors of the southern Dakota. 800 miles away.
Indeed, during their trip, neutrinos and anti-neutrinos undergo slight modifications.
Scientists want to know if these changes are different for neutrinos and anti-neutrinos. If this is the case. they could find the answer to the question of why the material and the antimatter do not cancel each other.
Dune is an international collaboration in which 1,400 scientists from thirty countries participate. Among them. Kate Shaw, of the University of Sussex, told me that the discoveries to come going to “transform” our understanding of astronomy: why our universe exist? the universe and the vision that humanity has of itself.
“It is really exciting to see that we have today technology. engineering and skills in computer software that will allow us to attack these big questions,” she said.

At the other end of the world, Japanese astronomy: why our universe exist? scientists use sparkling golden globes to seek the same answers. In all its splendor, it is like a temple of science, reflecting the cathedral of southern Dakota, located 9,650 km away. Scientists build hyper-k, which will be a larger and more efficient version of their current neutrinos detector, super-k.
The Japanese team will be ready to activate their neutrino beam in less than three years. several years before the American project. Like Dune, Hyper-K is the result of international collaboration. Mark Scott. from the Imperial College of London, believes that his team is in pole position to make one of the greatest discoveries ever made on the origin of the universe.
“We start soon. we have a larger detector, which should allow us to obtain greater sensitivity than a dune,” he explains.
The fact that astronomy: why our universe exist? the two experiences work at the same time means that scientists will learn more than with one. but he adds: “I would like to arrive first!
Linda Cremonesi. from Queen Mary University of London, who works for the Dune project, believes that arriving first may not allow the Japanese team to have a complete vision of what is really going on.
“There is an element of racing. but hyper K does not yet have all the ingredients necessary to understand if neutrinos and anti-neutrinos behave differently.
The race may be launched, but the first results are only expected in a few years. The question of knowing what happened at the beginning of time to give birth to us is a mystery. – for the moment.
