Curved spacetime, an Uncommon card
In physics, curved spacetime is the mathematical model in which, with Einstein's theory of general relativity, gravity naturally arises, as opposed to being described as a fundamental force in Newton's static Euclidean reference frame.

Curved spacetime quiz: 3 questions
Three questions on the Curved spacetime card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Which of these cards hits hardest (highest ATK)?
Answer
Parallel ATA. Parallel ATA 80 · Curved spacetime 77 · Jöns Jacob Berzelius 74 · Erbium 71 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Parallel ATA. Parallel ATA 68,000 · Curved spacetime 52,000 · Jöns Jacob Berzelius 35,000 · Bruno Pontecorvo 15,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Objects move along geodesics, curved paths determined by the local geometry of spacetime, rather than being influenced directly by distant bodies.
- This framework led to two fundamental principles: coordinate independence, which asserts that the laws of physics are the same regardless of the coordinate system used, and the equivalence principle, which states that the effects of gravity are indistinguishable from those of acceleration in sufficiently small regions of space.
- These principles laid the groundwork for a deeper understanding of gravity through the geometry of spacetime, as formalized in Einstein's field equations.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Curved spacetime article was read about 52,000 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 80: each hit it takes is cut by 32 %.
How to get Curved spacetime
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.
