Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
Only headache is assuming whoever found it could read it, and parse it.
Requires microscopy and a compute model of the right standard, right?
Like to actually parse the bits…
Sure super aliens could but could post apocalyptic humans in a few centuries, who have regained enough stability to care about such things?
