@future.explanation on Instagram: "What you are seeing is Musou Black, a coating engineered to absorb nearly all incoming light. Its microscopic surface structure traps photons, forcing repeated internal reflections until the light energy is dissipated as heat. With almost no reflection reaching your eyes, depth and shape disappear, creating the visual effect of a true void. Why it matters: Ultra-low reflectance materials are used in optics, scientific instruments, and aerospace to eliminate str

SCIENCE | FACTS | BEYOND | HISTORY | on Instagram: "Real diamonds are tested with lasers because their internal structure interacts with light in a unique way. Here’s what happens: A laser beam is fired through the stone Real diamonds refract (bend) the light sharply, creating distinct patterns They scatter laser light irregularly due to their crystal lattice Synthetic or fake diamonds show smoother, more uniform beams Laser fluorescence reveals internal flaws called inclusions — something only
