Have you ever wonder where we stand in the universe? Earth seems like a big place but how does it compare to other stuffs floating around the galaxy? A little search turned up this cool video showing the relative size of our universe.
Towards the end, the video does take the ranking out of context. It ranks Betelgeuse and Antares by themselves and then goes on the list the Supergiants. Both Betelgeuse and Antares are Supergiants, but they are not the largest of the class.
