This may be off topic, but, in my opinion, the background music was awful. I had to mute the sound. For all those who feel a need to add a soundtrack to similar astro-type videos, check out maschinegeist.org for ideas. Thanks a lot!

Well, I didn't quite say that. "Force" is a broad term, and gravity can certainly be treated as a force. The question, though, is whether it is a particle mediated force like the others. Certainly, the GUT/QM folks want to think so; there is an elegance to the idea. But nobody has had any luck making a theory like that work... and they've been trying a long time.
