I have been looking for the name of this show for 20+ years as I remembered seeing it as a kid (about 9 at the time) and thinking WOW! I want to know more! for years I have been trying to tell people about the things expressed in the movie that really impressed me as a kid and inspired my interest in space and beyond! since I haven't seen it since it's original airing, I can't say how good the production or even the acting is, if it's like the space 1999 series stuff, it looks cheesy now, but for it's time was extremely interesting and on the older TV's with poor reception we missed a lot of detail anyway. I don't remember how long it even was, but it captivated me at the time, and I wanted more. I wish I could find this on DVD or something! I know now that it was meant to peak interest in Einstein's theory or general relativity and help explain space/time, and I guess in a way it did Just that for Me! after all I saw it once and 34+ years later I still remember it!
