Sci fi doesn't fully emulate real life science. It's the other way around
So far, Macross F can be watched as a standalone series but if you dont mind some funky old anime, i highly recommend the original SDF Macross (dont mistake it with robotech). It's where it all begun afterall
Macross 7 is more like a side story to the whole scheme imo. Never gotten Macross Plus so i cant comment on that one. Macross Zero.... errr, i dont think that one was related at all but still a highly enjoyable OVA series.
