imagine this situation: there's a very similar planet to Earth with almost the same atmosphere and surface. we want to know what lies beyond the surface to know if life exists there. so could we send or observe radio waves or microwaves with a similar telescope as arecibo that penetrates several cm of pure aluminium and image the subsurface beyond it? (supposing we'd had enough technology able to see at those distances)?
