After watching this I remember that it took Voyager 1 and 2 33 years just to leave our solar system, traveling at a speed of 35,000 miles per hour. To get just to the nearest star –  the single very nearest star – it will take them 80,000 years at that speed. This shows the enormity of the speed at which the “viewer” travels in this video, billions of times the speed of light.

A Small Part of the Universe

This is the most awe-inspiring video I have ever seen. Words escape me.

There are about 400,000 galaxies in this animation. They are in their actual, real positions. The imaginary camera moves around to provide different viewpoints with impossible speed.

Our own galaxy, the Milky Way, contains an estimated 100 billion stars. Most recent estimates are that such a galaxy also has about 100 billion planets, roughly one per star on average. The Milky Way has an approximate diameter of 100,000 light years. This means light takes 100,000 years to go from one end of it to the other.

Every one of these dots in this video is such a galaxy. Some of them smaller than ours, some of them much larger. Each one of them has 100 billion stars, give or take.

Awe is too small an emotion. I have goosebumps.
