What is the Central Finite Curve, and is our Rick the 'prime' Rick?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

The Central Finite Curve is the walled-off cluster of infinite universes, engineered by Ricks, in which Rick Sanchez is guaranteed to be the smartest being alive, and it sits at the heart of the show's long misdirection about which Rick is the 'prime' one. This ledger separates what Rick and Morty actually establishes about the Curve and 'our' Rick C-137 from what the show leaves disputed, what fan theories it quietly complicates, and what it keeps deliberately slippery.

Established 6supported, uncontested

  • Canon establishes the Central Finite Curve as a defined portion of the multiverse: a wall built around infinity that separates every universe where Rick is the smartest being alive from the rest of the infinite multiverse, so that most, if not all, Ricks in the series live inside it.▰▰▱▱▱ likely2 points
    Supports
  • It is established that the Curve was engineered by Ricks: the precursors of the Council of Ricks together with Rick C-137 built a massive machine underneath the Citadel of Ricks that locks out travel to or from any universe in which Rick is not the dominant lifeform or the smartest being alive, perpetuating the myth among Mortys and aliens that Rick is always top of the food chain.▰▰▱▱▱ likely2 points

    • The Central Finite Curve was designed by the precursors of what would later become the Council of Ricks on The Citadel and Rick C-137 to wall off the infinite number of universes in which Rick is the smartest person alive from the rest of the infinite multiverse.Central Finite Curve - Rick and Morty Wiki analysis
    • Using an advanced variation of their portal-gun technology, they built a massive machine underneath the Citadel of Ricks designed to lock out travel to or from any universe, within the multiverse, in which Rick himself was not the dominant lifeform or the smartest being alive.Central Finite Curve - Rick and Morty Wiki analysis
  • Canon establishes that 'our' Rick is Rick Sanchez of Dimension C-137, one of the two titular protagonists, and that, tellingly, the Morty we follow is not even his own: C-137's Beth was murdered as a child, so the show's main Morty is actually the grandson of the Prime Dimension.▰▰▱▱▱ likely2 points

  • It is established that 'Rick Prime' is a separate character from our Rick: the Rick of the Prime Dimension, formerly nicknamed 'Weird Rick,' who is the overarching antagonist and catalyst of the series, was responsible for killing Diane in every dimension and Beth in Dimension C-137, and abandoned his own family long before Rick C-137 took his place.▰▰▱▱▱ likely2 points

    • Rick Sanchez of the Prime Dimension, also known as Rick Prime and formerly Weird Rick, is the overarching antagonist of Rick and Morty, as well as the catalyst for the events of the series.Rick Prime - Rick and Morty Wiki analysis
    • He was the Rick who was responsible for the deaths of Diane in every single dimension, and Beth Sanchez in Dimension C-137. Rick C-137 attempted to find and kill Rick Prime throughout the multiverse for decades, killing countless other Ricks in the process. Rick C-137 eventually landed in Rick Prime's original dimension and took his place, kick starting the events of the series.Rick Prime - Rick and Morty Wiki analysis
  • Canon establishes that Evil Morty's entire arc is escaping the Curve: after seizing the presidency of the Citadel in 'The Ricklantis Mixup,' he overcharges the Citadel's dimensional drive in 'Rickmurai Jack' to punch a hole in the Central Finite Curve and escape into the greater multiverse, destroying most of the Citadel in the process.▰▰▱▱▱ likely2 points

    • Meanwhile, Evil Morty leaves the Citadel in an escape pod just as it explodes, travelling through the wormhole and penetrating the Curve. Emerging in the greater multiverse, he sighs with relief, confirming that the Curve has been destroyed, before he opens a gold portal with his upgraded portal gun and steps through.Rickmurai Jack (plot) - Rick and Morty Wiki primary
  • It is established that Rick Prime abandoned the nihilist 'prime' ideology all Ricks pose as, mocking his counterparts for their attachment to Diane, and that in 'Unmortricken' Rick C-137 destabilizes ('fracks') the Curve to flush out Rick Prime, whose 'Omega Device' had erased Diane across every universe in existence, then finally kills him with Evil Morty's help.▰▰▱▱▱ likely2 points

Disputed 3credible sources disagree

  • How much of Rick's own backstory to trust is genuinely contested, because the show flags his account as unreliable: when interrogated about the origin of the portal formula in 'The Rickshank Rickdemption,' Rick C-137 deliberately told a 'slightly edited' version of his history as a ploy to hijack the machine and escape.▰▰▱▱▱ likely2 points

    • When Rick C-137 was captured and interrogated on the origins of the Portal Gun formula by Cornvelious Daniel in "The Rickshank Rickdemption", he revealed a slightly edited version of Rick Prime's visit in order to allow him to take control of the Brain-alyzer and jump-start his escape attempt.Rick Prime - Rick and Morty Wiki analysis
    • A notable aspect of Rick's development is that as the series has progressed, Rick's god-like status has been moved to the forefront of the story.Rick Sanchez - Rick and Morty Wiki analysis
  • Whether 'prime' points to our Rick or to the villain is deliberately muddled: Rick C-137 himself goes by the alias 'Rick Prime' while squatting in the Prime Dimension and is called 'The Rickest Rick,' yet the show's actual Rick Prime is the separate villain native to that dimension, and a third, unrelated Council of Ricks member also carried the 'Rick Prime' nickname for reasons the show never explains.▰▰▰▱▱ roughly even chance1 against2 points

  • Whether C-137 or Rick Prime is the true 'Rickest Rick' is left as a matter of perspective, and the creators openly disagree: Justin Roiland has said that by one definition Rick Prime, the Rick completely devoid of empathy, is the Rickest Rick, while Dan Harmon argues the Rickest Rick is C-137, the self-destructive one who was Rick Prime's victim and reinvented portal travel to hunt him.▰▰▰▱▱ roughly even chance1 againstsummary-sourced2 points

Debunked 2refuted by the evidence

  • The popular fan belief that our Rick, C-137, is the definitive 'original' or 'prime' Rick is complicated by canon rather than confirmed by it. The assumption is fed by C-137 being the protagonist, the 'Rickest Rick,' and by his literally using the name 'Rick Prime' while living in the Prime Dimension, but the show reveals 'Rick Prime' to be a distinct villain native to that dimension who invented interdimensional portal travel first, whose place and name C-137 merely took.Refuted byAs stated by Rick Prime, Rick C-137 is the only other Rick, besides the former, who actually invented portal travel independently. The rest of the Rick's throughout the multiverse were introduced to it by other Ricks, who in turn learned it from Rick Prime.refuted2 against3 points

  • The tidy definition of the Curve as simply 'any universe that has a Rick and a working ecosystem,' drawn from the comics, is contradicted by the show. The wiki itself flags the comic model's canonicity as questionable, because Simple Rick's dimension satisfies both criteria yet is stated to sit 60 iterations off the Curve.Refuted byThis contradicts information given in the show as Simple Rick is stated to be 60 iterations off it despite fulfilling both criteria.refuted1 against2 points

Unresolved 3no settled answer

  • The full nature and rules of the Curve are left deliberately slippery. Fans and the wiki fall back on competing informal models, and the show never nails down exact membership: one common reading holds that the Curve has 'no set parameters,' being wholly random and infinite yet finite in variability, like the infinite numbers between 1 and 2 that never reach 3.▰▰▱▱▱ likely1 source
    Supports
  • What actually lies beyond the Curve, and whether it stays broken, is kept vague. Evil Morty escapes into an under-specified 'greater multiverse,' and rather than exploring it the show quickly patches the rift: in 'JuRicksic Mort' dinosaurs repair the Curve, to Rick's own irritation that a rift he could have used as a season-long story arc was simply closed off.▰▰▱▱▱ likely2 points
    Supports
  • Whether Rick's tragic backstory, and the Diane reveal at the center of it, was always planned or a later retcon is left open by the show's own history. The villain went unnamed as 'Weird Rick' for years and was only christened 'Rick Prime' once the writers had settled the backstory, with the wiki noting an out-of-universe reason that the creators had not figured Rick's backstory out yet.▰▰▱▱▱ likely2 points

    • Rick Prime was known as "Weird Rick" until the Inside the Episode for "Solaricks" came out, where Dan Harmon and episode writer Alberto Lundy consistently refer to him as "Rick Prime."Rick Prime (Trivia) - Rick and Morty Wiki analysis
    • The out-of-universe reason may be because the creators did not have Rick's backstory figured out yet and when they did, they wanted to give this completely villainous Rick a unique nickname to clearly differentiate him from his other selves, including even C-137.Rick Prime (Trivia) - Rick and Morty Wiki analysis
