The facts on the card
The card carries these facts from its Wikipedia article.
- He later removed it, however, much later it was revived to express the energy density of space, or vacuum energy, that arises in quantum mechanics.
- It is closely associated with the concept of dark energy.
- Einstein introduced the constant in 1917 to counterbalance the effect of gravity and achieve a static universe, which was then assumed.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Cosmological constant article was read about 120,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 72: each hit it takes is cut by 29 %.
