"Roman's ability to observe wide areas of the sky to great depths, spotting an abundance of faint and distant galaxies, will revolutionize the study of cosmic voids," said Giovanni Verza of the Flatiron Institute and New York University, lead author of a new study published in The Astrophysical Journal demonstrating how Roman could examine voids, in a NASA statement.

"Cosmic voids potentially challenge a key notion in astrophysics known as the Copernican or cosmological principle. An extension of Copernicus' insight that the Earth does not occupy a special place in the universe, the principle holds that on the largest scales, the universe should appear largely homogenous with matter evenly and randomly distributed. But astronomers have been spotting cosmic voids tens of millions - and"
"which poke formidable holes in the idea that the cosmos should look basically the same in every direction, from any position. The voids form the center of "bubbles" on the surface of which galaxies cluster together, sort of like dust clinging to a balloon - a sign that galaxies aren't randomly distributed but themselves constitute even larger structures. Some of these structures span billions of light years across."
The Nancy Grace Roman Space Telescope will survey cosmic voids—vast regions with few or no galaxies—to probe the universe's evolution and the forces of dark matter and dark energy. Roman's wide-field, deep imaging will detect numerous faint and distant galaxies, enabling detailed mapping of void boundaries and internal properties. Cosmic voids challenge the cosmological principle by forming centers of bubble-like structures where galaxies cluster on surfaces, indicating nonrandom, large-scale organization spanning millions to billions of light years. Detailed void studies can test fundamental cosmological assumptions and constrain competing models of gravity and cosmic expansion.
