Star Trek, J.J. Abrams' 2009 reboot of Gene Roddenberry's fictional universe created some significant changes, and here are the biggest differences between the Prime and Kelvin timelines. Following the devastating destruction of Romulus, an embittered miner named Nero (Eric Bana) traveled back in time, attacking the USS Kelvin and creating an alternate Star Trek reality. The consequences of this event continued to ripple throughout the so-called Kelvin timeline for decades, meaning that history progressed similarly to established Star Trek canon, but with some major changes.
