 The universe is vast and filled with mysteries, two of the most enigmatic being dark matter and dark energy. These unseen forces make up the majority of the universe, yet their true nature remains elusive. At CuriousWorlds , we delve into the fascinating world of dark matter and dark energy, exploring what we know and the questions that still puzzle scientists. What is Dark Matter? Dark matter is a form of matter that does not emit, absorb, or reflect light, making it invisible to current detection methods. Despite its elusive nature, dark matter is thought to make up about 27% of the universe's total mass and energy. Its presence is inferred from its gravitational effects on visible matter, such as stars and galaxies. Evidence for Dark Matter Galaxy Rotation Curves: Observations of galaxies show that stars at their edges rotate faster than expected based on visible matter alone. This discrepancy suggests the presence of dark matter, providing additional gravitational pull. Gravi...
