These “black diamonds” aren’t the sparkly gems you see in jewelry—they’re tougher, darker, and formed under conditions no human could survive. It’s one of the most mysterious layers scientists drill into… and every sample pulled up tells a story billions of years old. Vis @mi

Explaining The Universe on Instagram: "A three-dimensional soft cell for holding liquid in space is a flexible, membrane-like container that relies on surface tension and capillary forces rather than gravity to keep fluids in place. In microgravity, liquids naturally form spheres and drift, so the soft cell’s curved walls, internal channels, and elastic structure guide the liquid and prevent it from breaking into floating droplets. As the membrane gently flexes, it helps reposition the fluid and

𝐇𝐈𝐒𝐓𝐎𝐑𝐘| 𝐈𝐍𝐅𝐎 | 𝐖𝐄𝐀𝐋𝐓𝐇 on Instagram: "This trick shows how a fingerprint left on a smooth surface can be lifted and turned into a replica that copies the ridge patterns of the original finger. With a clear enough print and a detailed replica, it’s sometimes possible to fool certain fingerprint sensors — especially older ones. But modern sensors use better detection methods, making them much harder to trick. Safety Note: Copying or using someone’s fingerprint to access their devi
