Dec 18, 2020 at 20:24 comment added TylerH "Archaeologists probably are interested in data 500 years old and older." You've just invalidated like half of the whole field of archaeology out there :-)

Dec 18, 2020 at 13:57 comment added John Dvorak @Anderas nice! Is there a photo of these barrels?
Dec 18, 2020 at 13:21 comment added Anderas @John Dvorak they literally use metal barrels like you can see elsewhere for transporting liquids. Here they are meant to keep out the liquids. It was meant to be a plan B if the nuclear war was coming and going, for re-kickstarting everyone into a civilization. I think the Germans are not the only ones who do this. Alexander, yes it is a SI unit if the barrel has 1000 litres :-)
Dec 18, 2020 at 12:05 comment added John Dvorak @Alexander my interpretation was that they dump capsule after capsule of tightly wound celluloid film into literal wooden containers until they no longer fit, then seal it them off and haul them to a man-made cave who knows where.
Dec 18, 2020 at 6:15 comment added Anderas So the method still exists. Good to hear. The material has a lifetime of 13.8 bn years at 193°C. At room temperature and low temperatures it should be longer.
Dec 17, 2020 at 22:43 comment added Michael Richardson In 2019, Microsoft recorded Superman on some kind of quartz glass. So if that ends up becoming a go-to method of data archiving, you then could easily last hundreds or thousands of years. Maybe longer. And one note in an article I found directly mentioned the University of Southampton. Quote from article "a virtually unlimited lifetime at room temperature." No mention how the OPs arbitrarily low temperature would treat them.

Grammar improvements
Dec 17, 2020 at 18:04 comment added Kaz @TheSquare-CubeLaw You should note that random data centres are unlikely to survive long in an apocalypse, but I bet there's at least a dozen groups out there dedicated to storing eg all the text of wikipedia in a massively durable medium.
Dec 17, 2020 at 18:02 comment added The Square-Cube Law This is good to know, thank you!
