The spelling is done to fit with the cheap edition. You know, something that's good for a kid to put on his bedroom wall. Ditto for the universe with a capital U. As to the gasket, it is a piece of material cut to seal something, and somebody at the publisher thought that it would be a fitting name for this artifact. :-) But, no, really, it's all intentional, though I could correct the spelling if it bothers you.
