What truly composes the universe? If you said stars, planets, gas, and dust, you would be mistaken. Three decades ago, researchers first identified a mysterious dark substance influencing galaxy movement. Currently, scientists estimate that dark matter exists in quantities five times greater than ordinary matter. Yet, its true nature remains a mystery, as it isn't composed of atoms or any familiar materials. Additionally, there’s another enigmatic force at play—Dark Energy—which appears to be accelerating the expansion of the universe itself.
