In Arizona, a telescope at Kitt Peak National Observatory has been working for three years to create a three-dimensional map of the sky. The Dark Energy Spectroscopic Instrument (DESI) has been studying the light from millions of galaxies in an effort to understand dark energy, a mysterious force that makes up a majority of the energy in the universe.
The initial findings from DESI suggest that the density of dark energy may not have remained constant since the beginning of the universe as previously believed. Dr. Dragan Huterer from the University of Michigan, who worked on the project, described the findings as “bizarre.” If these results are confirmed, it could lead to a major crisis in the field of cosmology. The discovery that the density of dark energy has been fluctuating over time would shake up our understanding of the universe and how it has evolved over billions of years.
