The facts on the card
The card carries these facts from its Wikipedia article.
- The predictions of BBN rely on a combination of thermodynamic arguments and measurements of rates of nuclear reactions that are expected to be active in the early universe.
- Refined models tend to agree well with observations of these light element abundances.
- The model is one of the key concepts in standard cosmology.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Big Bang nucleosynthesis article was read about 58,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 73 and blocks with 75: each hit it takes is cut by 30 %.
How to get Big Bang nucleosynthesis
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
