Dark matter is a hypothetical form of matter that does not emit, absorb, or reflect electromagnetic radiation, making it invisible and detectable only through its gravitational effects on visible matter and light. It constitutes approximately 27% of the total mass-energy content of the universe, making it one of the most abundant components of the cosmos. While its existence is supported by observational evidence such as the rotational curves of galaxies and the large-scale structure of the universe, the nature and composition of dark matter remain unknown, presenting a major challenge to our understanding of fundamental physics and cosmology.
