Ummmmm.......
- LoganDark 2y agoI guess wavelength and polarization of light? (I guess I have no idea how that's even possible to encode into a crystal, but it's two optical dimensions I suppose.)
- morning-coffee 2y agoYeah. That and > a revolutionary data storage format that can survive for billions of years Clearly it hasn't been verified to be able to survive for billions of years, but it is thought to be able to survive for billions of years based on extrapolation from tests done over time scales multiple orders of magnitude smaller.
