Summary: The text discusses the concept of dark matter, an elusive substance that makes up the majority of the universe's mass yet remains undetectable through current scientific methods. Scientists have hypothesized its existence based on gravitational effects observed in the cosmos, notably the rotation of galaxies. The search for dark matter continues through various experiments, such as the Large Hadron Collider, but its true nature and composition remain a mystery. Despite its invisibility, dark matter plays a crucial role in shaping the universe and its structures, influencing the distribution of galaxies and the formation of cosmic web. Further research and observations are needed to unravel the enigma of dark matter and its implications for our understanding of the universe.
