We already know what can last for literally millions of years: Life.
Maybe we could encode some information in birdsong, tree rings, or the matting patterns drawn by fish in the seafloor. :)

- vmilner 6y agoIt's fascinating that in 1983 it was thought that a 768-bit RSA number would take 40 million years to factor. (It actually took 26 - RSA-768 was factored in 2009.)
- shantara 6y agoThis reminds me of Whisper, one of my favorite exotic alien concepts. The alien civilization in question has selected a planet with as stable environment as possible, and planted it full of genetically engineered grass. The sound of wind blowing through the grass creates an acoustic computer which hosts a virtual space its creators have uploaded themselves into. https://www.orionsarm.com/eg-article/470007b39d192 https://www.orionsarm.com/eg-article/470007b39d192
