What Is Dark Matter | XPeer - Empowering Connections

Dark matter is a hypothetical and invisible form of matter that does not interact with light or other electromagnetic radiation. It is implied by gravitational effects that cannot be explained by [[general-relativity|general relativity]] unless more matter is present than can be observed. The existence of dark matter is supported by various lines of evidence, including the motion of galaxies within galaxy clusters and [[cosmic-microwave-background|cosmic microwave background]] anisotropies. Despite its elusive nature, dark matter has been extensively studied through its gravitational effects, and researchers continue to explore its properties and behavior using advanced telescopes and simulations, such as those conducted by [[nasa|NASA]] and [[esa|ESA]].
