If scientists can ever miniaturize neutrino emitters and detectors it would be amazing for point-to-point light speed communication literally through the planet.

Why is it so difficult to detect neutrinos?

You just answered your own question. A whole planet won't stop them - how will your detector?

That’s the challenge! What are your ideas?

Maybe some kind of exotic materials. Meta materials?

Also you only have to detect a small amount but you could send out a very large amount.

It might be how aliens communicate too.
