The Dark Energy Spectroscopic Instrument research group says it has created the largest 3D map of the universe ever constructed, spanning over 11 billion years.
This elusive component — while unseen — plays a crucial role in shaping the cosmos. It tells us about how the universe evolved from its infancy to its current state, while also hinting at its potential future trajectory. collaboration, a group examining light from the farthest corners of space to determine how these forces affect the evolution of the universe — specifically, how it is expanding.
The research group says it has created the largest 3D map of the universe ever constructed, spanning over 11 billion years. It is the first time scientists have been able to measure the expansion of the early universe with an accuracy better than 1%, Ishak-Boushaki said. The instrument used in this research is located at Kitt Peak National Observatory in Arizona., “there’s more to the universe than the matter we can see.
Dark energy, on the other hand, seems to push galaxies away from each other at an ever-increasing rate. This is thought to be responsible for the accelerating expansion of the universe, a 1998 discovery that earned thethrough observations of distant star explosions. The supernovae emitted less light than expected, indicating the universe was expanding faster than previously thought.
Although more work needs to be done, Ishak-Boushaki said these findings may indicate that physicists need to modify Einstein’s theory of gravity at large scales in the universe.“The fact that this dark energy parameter changes in time means that the acceleration of expansion may happen in a different way than thought before,” he said. “If this result grows in significance, this is a very important result for the entire cosmology and physics scientific communities.”.
