Ambassador Spock used red matter onboard the Jellyfish to create a black hole in order to consume the star's energy, however, the supernova reached Romulus and destroyed the planet and all inhabitants. Among those killed were the wife and unborn child of Nero, who swore vengeance against Spock, Vulcan, and the Federation for letting his world and family die. When Nero confronted Spock in the Narada, both ships were pulled into the black hole which had consumed the star and sent them back in time. This event created an alternate reality.
