The facts on the card
The card carries these facts from its Wikipedia article.
- Since the 1960s, various kinds of gravitational-wave detectors have been built and constantly improved.
- The present-day generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves from astronomical sources, thus forming the primary tool of gravitational-wave astronomy.
- The first direct observation of gravitational waves was made in September 2015 by the Advanced LIGO observatories, detecting gravitational waves with wavelengths of a few thousand kilometers from a merging binary of stellar black holes.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gravitational-wave observatory article was read about 14,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 64: each hit it takes is cut by 26 %.
How to get Gravitational-wave observatory
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.
