This is a cool presentation and idea, however my spidey senses....they be tinglin'. The number one reason why is because of the various planar discrepancies this model offers. For the most part, relative to our point of view, the planets' orbits are coplanar (on the same plane). Maybe this model would offer the same "effect" but I'm not about to try the math. It just seems like a "earth is flat" theory to me (although more convoluted).

As above, so below.

Doesn't our whole solar system eventually end up out the other end of a humungous black hole??

Ya, there is a group using this visualization to show that "gravity is a lie" so your spidey sense is right on the money. When you get down to it, the motion around the center of the galaxy is inconsequential, the orbit of the planets around the sun would be the same. And the gay spiral bs at the end, well, that is not taking into account the motion of the galaxy through deep space, making the the pattern of our motion through space just look like an oscillating mess, not a spiral. Not to mention we might get ejected when Andromeda smashes into us. In the end, all the mass in our solar system was created with angular momentum around the galactic core, and internally, the system was embedded with angular momentum around the sun.

Yeah, it struck me as pretty, but I was under the impression that the orbital plane was pretty close to the galactic plane so it would look more like the first model they showed, just adding that the sun itself was orbiting another object... Sort of like if you wanted to watch the moon in an animation like this you wouldn't show the Earth and the moon looking like a comet, but trace the Earth's orbit and show the moon's orbit around the sun. The orbital plane and galactic planes may not line up exactly but close enough I would think to offset the model presented in the video. Pretty though.

Agreed with all of you...but it's got nice background music, so I'm down with it.
