What is the reason that Diggy Simmons clothing line is referred to as "Space Age"?

Daniel "Diggy" Simmons is the son of Joseph Simmons a.k.a. "Reverend Run" of Run D.M.C. They appear on "Run's House", the reality show that follows the lives of the Simmons family. (http://www.mtv.com/ontv/dyn/runs_house/series.jhtml) Diggy is in the 7th grade and is planning on starting his own clothing and shoe line, called "Space Age". I've done a LOT of searching (he is mentioned on a LOT of myspace pages), and can find no reference to the meaning of the name. You'd have to ask him. Me? I'm just thinking it sounded cool to him. Drop him a line at the "Run's House" MySpace page if you want to see if he'll give up the "why" behind the name. (http://profile.myspace.com/index.cfm?fuseaction=user.  more
