Emerging Evidence Indicates Universe's Expansion Is Decelerating

A new study suggests that the universe's expansion is slowing down rather than accelerating, challenging the long-held belief that dark energy is causing an ever-increasing expansion rate. The findings indicate that dark energy may weaken over time, leading to a transition from acceleration to deceleration, which could significantly alter our understanding of the universe's past and future.

Early Universe's Sound Implies We Live in a Vast Void

Scientists suggest we live in a large cosmic void, which could explain the faster-than-expected expansion rate of the universe (Hubble tension). Recent analysis of early universe sound waves and galaxy distribution supports this idea, making the void model significantly more likely than the standard cosmological model without a void. Further measurements are needed to confirm this hypothesis.
