Astrophysicists have made one of the most detailed studies ever of the formation and evolution of the universe. Pantheon+ The way we understand space and the universe could change with this work. Because this study the structure of the universe and the rate at which the universe is expanding reveals new information about

A third of our universe, according to study largely It consists of matter in the form of dark matter, two-thirds of which is dark energy. The expansion of the universe has accelerated over the past billion years.

Now it will be easier to explain the cosmos

Standard cosmological model The prevailing modern cosmological theories, known as Pantheon+ While it is backed up with the artwork again, in a way it also rejects the alternative theories of dark matter and dark energy. New studies on dark energy and dark matter, the model’s greatest mysteries, may be taking shape through Pantheon+.

He is an Einstein researcher at Harvard & Smithsonian’s Center for Astrophysics. Dillon Brout, in the statement “With these Pantheon+ results, we are able to place the most precise constraints ever on the dynamics and history of the universe. We combed through the data and now we can say with more confidence than ever how the universe has evolved through the ages. and that the best theories available for dark energy and dark matter are strong.” he said.

In the Pantheon+ study Type Ia white dwarf stars called supernovas examined. When these supernovae explode, they create flares that can be clearly seen even 10 billion light-years away, so these explosions can be seen from most of the known universe.

These studies reveal the expansion rate of the universe.

to the center of the explosion as the distance grows brilliance weakened. Scientists also manage to reveal the expansion rate of the universe with their studies on the remnants of these explosions and their distances from the center.

According to new research, 66.2% of the universe is made up of dark energy.33.8% is a mixture of matter and dark matter. Another important finding is the expansion rate of the universe. Measured with a margin of error of 1.3 percent is the universe per megaparsec (1 million persec, about 3,262,000 light-years). 77.3 kilometers per second continues to expand rapidly.

With the Pantheon+ study, researchers have determined that the universe originates from the dark matter-dominant structure. dark energy dominance It says it is possible to observe the transition. researchers, “Pantheon+ gives us the best chance to limit dark energy, its origin and evolution” expressions used.
