The facts on the card
The card carries these facts from its Wikipedia article.
- The radius of this region is about 14.26 gigaparsecs.
- The word observable in this sense does not refer to the capability of modern technology to detect light or other information from an object, or whether there is anything to be detected.
- It refers to the physical limit created by the speed of light itself.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Observable universe article was read about 460,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 75 and blocks with 85: each hit it takes is cut by 34 %.
