The Dark Matter Anomaly (DMA), so named by Commander Paul Stamets, was a highly destructive gravitational anomaly of unknown, possibly extragalactic origin. Initially believed to be a natural phenomenon, it was later discovered to be an artifical construct created by a party termed by Federation Security as "Unknown Species 10-C".

Characteristics

The DMA measured five light years in diameter and exhibited a gravity well and gravitational distortions consistent with a wormhole. It produced subspace gravitational waves of extreme power, which caused catastrophic gravitational shearing to any object within twelve AU of its ergosphere. It was surrounded by an accretion cloud containing debris and a massive amount of dark matter. It did not emit tachyons. The anomaly moved through space and was capable of changing direction. (DIS: "Kobayashi Maru", "Anomaly (DIS)", "Choose to Live")

The DMA presumably traveled significantly faster than light, as evidenced by it affecting Deep Space Repair Beta Six and the Kwejian system in quick succession despite the two being light-years apart.

History

The anomaly was discovered by the United Federation of Planets in 3190 after it struck Deep Space Repair Beta Six and the Kwejian system, where it destroyed Kwejian and its moon. It was projected to enter the Riscot system next, though it soon changed course. (DIS: "Kobayashi Maru", "Anomaly (DIS)")

The USS Discovery subsequently collected detailed sensor readings on the anomaly with the assistance of Cleveland Booker and his ship. President T'Rina offered the services of the Ni'Var Science Institute in analyzing the anomaly. Based on this data, preliminary hypotheses of the DMA being binary black holes in the process of merging, or a primordial wormhole, were discarded. (DIS: "Anomaly (DIS)", "Choose to Live")

Later that year, the DMA – while under observation by the USS Janeway and NSS T'Pau – exhibited an unusual spike in X-ray radiation before it abruptly disappeared from the Venari sector and re-appeared 1,000 light years away. This behavior, which seemed to defy all physical laws, revealed the existence of an artificial device at its heart, proving that the anomaly was not a natural phenomenon but rather a construct under the control of a party Starfleet designated "Unknown Species 10-C".

The DMA's change in locale put it on a course to fly by the Radvek chain. The colony was successfully evacuated by Discovery before its destruction, with the exception of Felix, a prisoner who declined to leave. (DIS: "The Examples")

During a summit between the Federation members and allies, Ruon Tarka, a scientist claiming to be from Risa, revealed a special weapon that he wanted to use on the anomaly that would use a Isolytic burst to destroy the DMA. However, the risk of damaging subspace and rendering warp travel inaccessable there proved too risky and the summit ultimately voted for a more peaceful First contact with Unknown Species 10-C. Tarka, undeterred, confronted Book and persuaded him to join him in destroying the DMA as the device powering it was possibly powerful enough to allow one to cross to an alternate universe and the hope of an intact Kwejian.
