Story summary

The KBC void, a colossal gap in the cosmos, could hold the key to the Hubble tension—a puzzling difference between local and distant measurements of the universe's expansion rate. This anomaly questions the Lambda Cold Dark Matter model, leading astrophysicists to suggest the ?HDM model, which may revolutionize our grasp of cosmic structure and the universe's age.
