You recognize what these are, right? Capillaries, the tiniest blood vessels in an animal's body. These are the vessels that run throughout our bodies, bringing cells oxygen through the red blood cells and helping to clean away the cellular waste products.
Except that, of course, what we're looking at isn't tiny, but gargantuan. The opening sequence starts at 1 Gpc/h; one gigaparsec. A parsec is a unit of length in astronomy, approximately 3.262 light years in length. The closest star to the sun, Proxima Centauri, is 1.29 parsecs away. A gigaparsec is one billion parsecs in length.
The video slowly flies into a central point (presumably the neighborhood of the Milky Way), where we begin to realize that all of these "capillaries" are really strings of galaxies that are connected together in a type of capillary formation through gravitational forces.
The video stops moving forward at 3.9 Mpc/h (megaparsecs); i.e., 3.9 million parsecs or 12,721,800 light years in distance. Here, we can easily make out individual galaxies. The video then reverses flight until we reach the 1 Gpc/h distance once more.
Beautiful, ain't it. And, once more, helping us to realize just how small and insignificant we all are (and our problems), and just how immense the power and majesty of Allah (swt) is, who is able to create and sustain all of this.
Allah! There is no God save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave ? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous. (2:255)
