USS Beagle

The USS Beagle was a Earth spacecraft from an alternate quantum reality.
== History ==
In 2382, the Beagles exploration of other quantum realities inadvertently opened up quantum fissures all over the multiverse, including in the prime universe, which weakened the fabric of the multiverse. ()
The Beagles existence was discovered by Lieutenant junior grades Brad Boimler and Beckett Mariner when they studied a fissure located in Klingon space and determined that it was manmade rather than a natural occurrence. ()
Section 31 eventually sent Boimler's transporter duplicate Captain William Boimler in the starship Anaximander to find the source of the rifts and stop it. With the crew being made up of "interdimensional castaways" stranded far from their own realities by the Beagles rifts, the Anaximander was able to draw the Beagle to their location and fired upon the other ship, chasing it through another rift. Lacking deflector shields, the Beagle suffered heavy damage and was forced to make an emergency landing on Khwopa where both crews were captured by Khwopians. Meeting each other face-to-face for the first time, the Anaximander crew learned that the Beagle was simply an exploration ship from another reality led by Captain Lily Sloane and her crew were unaware of the detrimental effects of their quantum reality drive.
Sloane agreed to help the Anaximander crew return home to their respective realities and the two crews worked together to repair the ship. However, Lieutenant junior grade Harry Kim kidnapped his counterparts and hijacked the Beagle, intending to return to his own reality despite the fact that the Beagles repairs were still incomplete. In its damaged state, the ship began to break apart as it launched into space and the other Kim's fought their deranged counterpart for control. The deranged Kim beamed his counterparts to the Anaximander and, ignoring all warnings, flew the ship into a rift. Unable to handle the strain, the Beagle exploded moments after entering the rift, disrupting its coherence and threatening to send destructive soliton waves across all quantum realities. Sloane and Beckett Mariner were able to use the Anaximanders navigational deflector to direct the wave into the prime universe where William believed that his duplicate and friends on the would be able to find a solution to save the universe from destruction. ()
Having been on the Anaximander when their ship was destroyed, the Beagle crew joined the crew of the Section 31 ship, later joining them in going to the prime universe once the danger was over. ()

=== Background information ===
The overall shape of the Beagle is evidently inspired by that of the , which was previously established as an early Earth spacecraft predating the . This design was itself originally based on concept art by Matt Jefferies, which made its debut in canon in .
The Beagle is named after the , the British Royal Navy ship that served as the setting for English naturalist Charles Darwin's five-year expedition around the Earth, upon which he made notes on all the different variations of finches that evolved on Galapagos to fill the different niches.
As the prime Lily Sloane was already an adult Human in 2063, it is unclear if the alternate Sloane is extraordinarily long-lived, or if the Beagle can travel across time as well as realities. Previous example of traveling through Quantum Fissure stated uncertainty principle indicates time is a variable in quantum physics, resulting in going back in time when crossing dimensions.
