I'm playing a game with SE and your Very BZ modpack. SE's beginner space technologies require just red, green, and blue science to unlock. Cermet requires purple science, and is a prerequisite research for almost all of those starting space tier techs. This feels like a mistake. I think either cermet's science requirements ought to be changed to match its place in the tech tree, or I guess making the early space buildings not require it and moving the tech down a little would work too.
