Star Trek: Discovery season 4 officially confirmed that the Multiverse exists, but with Discovery coming to a close, the Star Trek franchise cannot forget about the Multiverse. Star Trek: Discovery premiered in 2017, and the show's popularity facilitated the largest expansion of the franchise since the end of Star Trek: Enterprise in 2005. Discovery allowed for the creation of several other Star Trek projects, including its spin-off series Star Trek: Strange New Worlds. In March 2023, however, it was announced that Discovery's upcoming fifth season would be its last.
During its time on the air, Star Trek: Discovery added to and expanded upon the franchise in some significant ways. One of these was the official confirmation of the Star Trek Multiverse in season 4. The idea of a Multiverse had been explored in previous projects with concepts like the Mirror Universe and the creation of the Kelvin Timeline in J.J. Abrams' Star Trek (2009), but it wasn't until Discovery season 4 that Star Trek confirmed that the Multiverse did indeed exist. The Multiverse was verified by Dr. Ruon Tarka (Shawn Doyle), who told Cleveland Booker (David Ajala) that there were an infinite number of parallel universes, each with a unique quantum signature, when discussing his plan to reach one of these in Discovery season 4, episode 7, "…But to Connect."
