One of the weirdest things for us humans to explain to space aliens is our affiliation for electromagnetic radiation between 420 to 750 terahertz. The ETs are like "why the heck do you have these 'lamps' and 'LED screens' and 'plants'?" We're like "haven't you heard of light?" and they're like "he ain't heavy, he's my brother" and we're like "we're not talking about your hot symbiotic co-pilot growing out of your forehead, which, cool look btw" and they're like "'hot', 'cool', 'look'? More radiation talk".

"Terrans have hundreds of words for radiation", they'll say.

Uh, I'm gonna try to sleep some more, big day today. Just wanted to send a report from my oneironautic space travels.
