Dark Energy Spectroscopic Instrument (DESI)) has been making important contributions to scientists for years in mapping the universe. Finally, a 3D map created with the help of DESI was shared. This map is considered the largest 3D map of the universe ever created.
Map, more than 6 million It contains the galaxy and sheds light on the 11 billion-year expansion adventure of the universe. The map was created by the work of 5000 small robots.
Dark Energy and the Expansion of the Universe
Researchers are making detailed studies on this map to understand the effects of "dark energy", which directs the expansion of the universe and still maintains its mystery.
The data examined with the map confirms that the universe is expanding. However, one thing that has surprised scientists is that dark energy can behave differently than expected. Observations show that dark energy is not constant over time and may have experienced changes throughout the history of the universe.
One of the authors of the study, Dr. “The observed changes provide exciting clues that dark energy is evolving over time,” said Seshadri Nadathur. This shows that our current dark energy models need to be reviewed.”
DESI's work will continue and continue to provide new information about the mysteries of the universe. Researchers will continue their work to confirm their findings with more data and to better understand the evolution of the universe.
