Quartz glass holds data for hundred million years

The video tutorial explains a special type of glass that is 2 centimeters square and 2 millimeters thick, capable of storing data in binary form by creating dots within its layers. This glass is waterproof, resistant to magnets, and can withstand heat up to 1000 degrees Celsius for two hours without damage. The technology allows data storage at a density equivalent to that of a CD, with the data lasting over 300 million years.
