Matter: Dark

Dark matter makes up roughly , dwarfing the "ordinary" matter—stars, planets, and people—which accounts for less than 5%.

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? Dark Matter

It does not interact with electromagnetic forces, meaning it is completely transparent. Dark matter makes up roughly , dwarfing the

The exact identity of dark matter remains unknown, though several leading theories exist: The quest for dark matter with Matt Bothwell 🧪 What Could It Be

Scientists discovered dark matter not by seeing it, but by noticing that the universe's "math" didn't add up without it. Galaxy Rotation Curves

Most evidence suggests dark matter is "cold," meaning its particles move slowly relative to the speed of light. 🔭 Key Evidence
