"The Quest for the Most Elusive Material in Physics" - you mean the Rasu?
It shouldn't be a huge spoiler to say that in TSLG, our Asterion friends expend some time and effort trying to decipher exactly what the Rasu *ARE*. While, don't worry, I don't go into this level of science-gasm detail, in my head I imagine that some of the experiments they run look a little like these. 😎
