Could we use arecibo radar frequencies to read a message in a paper in an alluminium ball buried in a planet?
I was just wondering, do you think it's possible to use Arecibo radar frequencies to read a message in a paper that's inside an aluminum ball buried in a planet?
Arecibo radar is certainly powerful enough to penetrate through solid objects, but I'm not sure about its ability to read a message written on paper inside an aluminum ball. That would depend on the thickness of the aluminum and the clarity of the message.
