The exact identity of dark matter remains unknown, though several leading theories exist: The quest for dark matter with Matt Bothwell
It provides the "glue" that keeps galaxies from flying apart. Dark Matter
Massive objects warp the space around them, bending light like a lens. By observing how light from distant galaxies is distorted, astronomers can map the "invisible" mass causing the effect, which consistently points to vast reservoirs of dark matter. 🧪 What Could It Be? The exact identity of dark matter remains unknown,
Most evidence suggests dark matter is "cold," meaning its particles move slowly relative to the speed of light. 🔭 Key Evidence 🧪 What Could It Be
Dark matter is one of the most significant mysteries in modern science, representing a substance that does not emit, absorb, or reflect light, yet exerts a powerful gravitational pull on the universe. While it remains invisible to traditional telescopes, its presence is inferred by its impact on the visible world. The Cosmic Invisible
It does not interact with electromagnetic forces, meaning it is completely transparent.
Dark matter makes up roughly , dwarfing the "ordinary" matter—stars, planets, and people—which accounts for less than 5%.
