In the vast cosmos, the familiar atoms and light that makeup everything we see constitute less than five percent of the universe. The rest comprises dark matter and dark energy—mysterious substances that dominate the universe’s structure and evolution. Despite their enigmatic nature, these phenomena are fundamental to comprehending the cosmos.
The universe’s accelerating expansion suggests a force called dark energy, which constitutes about 68% of the universe’s energy content. Scientists at the Center for Astrophysics | Harvard & Smithsonian study dark energy using methods like Type Ia supernovas, Baryon Acoustic Oscillations (BAO), and fluctuations in the Cosmic Microwave Background (CMB). Advanced instruments and surveys continue to enhance our understanding of dark matter and energy, aiming to unravel their nature and roles in the universe’s evolution.
