A recent paper from the Dark Energy Spectroscopic Instrument presents evidence for dynamical dark energy, challenging the cosmological constant model and potentially revolutionizing cosmology.
A study published in Nature presents evidence that the universe may not be uniform on the largest observable scales, challenging a fundamental pillar of modern cosmology. Researchers found persistent coherent structures in galaxy distribution that do not fade into a uniform background as expected.
Cosmic voids, vast empty regions of space, may help solve mysteries about dark energy, gravity, and the Hubble tension. New telescopes and simulations are enabling detailed study of these voids.
