For decades, scientists have believed that dark energy drives the universe’s expansion. However, a new study suggests this assumption may be incorrect. Researchers from the University of Canterbury found that the universe is not expanding uniformly in all directions. Instead, it grows in a “lumpier” way, with variations in different regions.
This discovery could potentially eliminate the need for dark energy, which has been a long-standing puzzle in cosmology. The researchers propose an alternative model of cosmic expansion, suggesting that unusual light stretching effects are not caused by how the universe is expanding, but rather by our understanding of time and distance.
According to David Wiltshire, lead author of the study, “Dark energy is a misidentification of variations in the kinetic energy of expansion.” The team’s findings provide compelling evidence for this new perspective, which could resolve some of the key questions surrounding the universe’s quirks.
With the release of new data, it’s possible that the universe’s biggest mystery could be solved by the end of the decade.
