308K views · 2.2K reactions | Since the dawn of time, two invisible forces, dark matter and dark energy, have been locked in an epic battle for control of the cosmos. At first, dark matter controlled the early universe, helping build stars, galaxies, and the cosmic web. Five billion years later, dark energy became the universe’s most powerful force and will determine the fate of all creation. #HowTheUniverseWorks | Science Channel | Facebook

Dark matter is one of the largest mysteries of our cosmos-- ubiquitously abundant and invisible to the eye, yet it controls the fate of all that surrounds us. We know little about dark matter's composition, and what we do know only leads to more questions. Might there be a "dark" Earth after all? #ScienceChannel #HowTheUniverseWorks | Science Channel
