Dark matter is a type of matter in the universe that does not absorb, reflect or emit light, which makes it impossible to directly detect. In recent years, astrophysicists and cosmologists worldwide have been trying to indirectly ...
It takes expensive tools to learn about the universe, but projects like the Very Large Array for radio astronomy in New Mexico and the Chandra X-ray Observatory, which orbits Earth, have pushed scientific knowledge forward ...
