DESI was built to conduct massive surveys of the sky that could measure the expansion of the Universe with great precision. By doing so, scientists hope to learn more about dark energy and dark matter, which makes up 95 percent of the Universe.Big Bang: Everything you need to know about the most accepted cosmological model
“So far, we’re seeing basic agreement with our best model of the universe, but we’re also seeing some potentially interesting differences that could indicate that dark energy is evolving with time,” he continued. “Those may or may not go away with more data, so we’re excited to start analyzing our three-year dataset soon.”
The scientists compared data from previous studies with the new DESI findings. They found some subtle deviations from Lambda CDM predictions in their observations.It’s worth noting that DESI will conduct a five-year survey, meaning it will provide a clearer picture in the coming years. If more data corroborates the deviations noted so far, they may point toward a need to update existing models.
