Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced confounding results.

Credit: NASA / SpaceX SPHEREx, is NASA’s newest astrophysics observatory, designed to uncover the mysteries and origins of the Universe, and will map the sky in over 100 different wavelengths.

Galaxies and galaxy clusters are not uniformly distributed throughout the universe; rather, they congregate into vast clusters interspersed with enormous voids where very few galaxies exist. The ...
