Spock’s FinalStar TrekDeath, Explained
Spock Died Alone, Far Away from Those He Knew And Cared For
While Spock was contemplating life in general, it is easy to see, in his assertion that people die alone, that he was predicting his own death. In the late 24th century, theRomulan Empire was threatened by a supernovain its home star system, and Spock, who had devoted his life to Romulan/Vulcan reunification, agreed to help. As seen in 2009’sStar Trek, Spock’s efforts were for naught, and Romulus was destroyed. Furthermore, thanks to the technology Spock used, he was sent back in time, helping create the Kelvin Universe.
If this law holds, then not only did Spock die alone, he most likely died in great pain.

The Kelvin Universe would turn out to be Spock’s final resting place.After helping the KelvinEnterpriseon at least two occasions, Spock passed away, as seen in 2016’sStar Trek Beyond. While the film did not reveal how Spock died,Star Trek: Discoveryexplained, in its third season, that travel between universes can be a dicey proposition, one with potentially deadly consequences for the health of those who do. If this law holds, then not only did Spock die alone, he most likely died in great pain.
