Explain dark matter and dark energy |

Answer» Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but accounts for most of the matter in the Universe. The existence and properties of dark matter are INFERRED from its gravitational effects on visible matter, radiation, and the large-scale structure of the Universe. It has not been detected DIRECTLY, making it one of the greatest mysteries in modern astrophysics. |
