The universe is vast and mysterious, with over 85% of its mass composed of an invisible substance known as dark matter. Unlike ordinary matter, dark matter does not emit, absorb, or reflect light, making it challenging to study directly. Scientists continue to delve deeper into this enigma, uncovering its role in cosmic phenomena and the ...
