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.

What a delightful article. Just enough humour interspersed to make it enjoyable to read without going on long tangents to make it annoying. And as someone who has very limited knowledge of this stuff, I feel like I've actually learned something!

The video[0] at the end of the article was also very beautiful and concise. I wish more scientific writing was done in this way.

Very well written, I like how playfully the author talks about the subject. The metaphors are essentially correct and work to bring the level of technicality down for people who can't spend dozens of hours on the subject. Most of us want to get a quick summary where we understand something when we can't invest the time it might otherwise take to get intellectual gratification.
