"The kingdom of God does not come with your careful observation, nor will people say, 'Here it is,' or 'There it is,' because the kingdom of God is within you." Luke 17:21
It's a little more complex than portrayed in the video. The Milky Way rotates on its axis -- perhpas the vector of the sun in the video represents that rotation. If not, what movement does it represent? The expansion of the universe? Gravitational attraction between adjacent galaxies, galaxy-clusters or super-clusters? I speculate the "true" path of the sun is not a straight line or even a very flat curve, but something a lot more complex than that. Although, perhpas if you represented every movement from every corner of Reality to which the sun is subject perhaps the net result would be no movement. :)
This is my second comment on this post.OK, having now jumped ahead to one of his later videos I see the issue of galactic rotation is accounted for...
Spirals within spirals. So strongly resembles a Chinese dragon!
