To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB.

Just because matter is visible doesn’t mean it’s easy to see.
From Physics, Jan. 31, 2023: Fermilab scientists are part of a group of researchers using cross-correlation measurements combining data from the Dark Energy Survey and the South Pole Telescope to determine cosmological parameters with greater precision. The analysis involved more than 150 researchers with results published as a set of three articles in Physical Review D.
Their analysis combines Dark Energy Survey, South Pole Telescope data to better understand the evolution of universe.
From Big Think, Nov. 2, 2022: Don Lincoln explores Hubble tension, two very precise yet conflicting estimates of the rate at which the Universe is expanding. While the of Universe expansion is consistent, the two ways in which this is measured begs the question if something is missing in cosmology theory.
After less than a year of data taking, DESI has already mapped out more galaxies than all previous 3D surveys combined — and it’s just getting started.
Physicists are revisiting what they previously assumed about how dark matter interacts with itself.
Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once.
What if human analysis, combined with machine learning, could advance the study of the universe? The U.S. Department of Energy awarded Fermilab scientist Brian Nord a $2.5 million Early Career Research Award to explore that possibility. Nord has envisioned a new hybrid data-analysis method to undertake the project. It integrates the strengths of artificial intelligence and interpretations of statistics in ways that could potentially advance the studies of cosmology.
From Universe Today, May 30, 2021: The Dark Energy Survey camera (DECam) was funded by the Department of Energy (DOE) and was built and tested at Fermilab. The DES took place over 6 years from 2013 to 2019, and looked at over 1/8th of the night sky for a total of 758 night
