Scientists at the University of Southampton have unveiled a stunning leap in data preservation — a 5D glass disc that can store 360 terabytes of information and remain intact for billions of years.

Made from quartz glass, this innovation uses ultrafast femtosecond lasers to etch data into nanostructures that encode information in five dimensions: X, Y, Z position, size, and orientation.

Each disc can withstand temperatures up to 1,000°C, resist radiation, and never degrade over time. To put its capacity in perspective, a single disc could hold the equivalent of 7,000 Blu-ray movies or the entire written history of humankind — preserved in a piece of glass small enough to fit in your hand.

This technology, already tested by Microsoft’s Project Silica, could one day revolutionize data storage for space exploration, cloud computing, and historical archives. Scientists have already stored texts like the Bible, Magna Carta, and the Universal Declaration of Human Rights, transforming glass into humanity’s most durable digital time capsule.
