Dark energy research

Dark energy is a mysterious force that makes up about 68% of the universe and causes its expansion to accelerate. Researchers study it by observing distant supernovae, galaxy clusters, and the cosmic microwave background to understand how the universe’s expansion changes over time. They use telescopes and satellite data to gather clues about its properties and behavior. Although its exact nature remains unknown, uncovering dark energy is crucial for understanding the universe's past, present, and future, and it could reshape our knowledge of fundamental physics.
