Heart of glass: Human genome stored for 'eternity' in 5D memory crystal
5D memory crystal is not really crystal. "It's silica glass," Kazansky said. "It's not like the glass in windows. It's similar to what's used in fiber. It's very pure silica, and it's very durable." It's tougher even than tardigrades. The fused silica can withstand temperatures of up to 1000°C, force up to 10 tons per cm 2, and cosmic radiation.
