Xeelee construction material is a material used by the Xeelee for most of their construction. It is made of exotic matter and is very dense. It violates the Pauli exclusion principle because it allows electrons to share quantum states. It is created by a Xeelee flower.
Trivia[]
- The material of the alien ship in the "Cilia-of-Gold" short story also violates the Pauli exclusion principle. This could imply that the aliens in that story could have had contact with the Xeelee (or are the descendants of the Xeelee).
