Tenet
Warning : MAJOR SPOILERS ahead forTenet .
Director Christopher Nolan is known for having unlawful timelines in his moving picture , butTenet ’s key conception of fourth dimension travelling via the inversion of S pee-pee for Nolan ’s most confusing - and fascinatingly layered - timeline yet . John David Washington leads the roll as a manknown only as the Protagonist , who is recruit to a top secret organisation that ’s fighting a warfare against a future enemy .
Nolan first made waves in 2000 with the discharge of his featureMemento , whose narration was told in inverse - chronological order from the perspective of a mankind with amnesia trying to puzzle out a murder mystery . Nolan ’s 2010 high - concept sci - fi movieInceptionfeatured a story where events spread simultaneously but not at the same focal ratio , due to the time dilation on dissimilar degree of dreaming . 2014’sInterstellarexplored the effect of space travel on time , and even Nolan ’s 2017 warfare movieDunkirkhad an improper timeline . WithTenet , Nolan returns to the field of theoretic aperient and turns a hypothesis about the possible inversion of time into a story about preventing World War III .

Tenet’s Timeline & Chronological Order Of Events
dogma ’s timeline may be complicated , but the friend ’s floor is told in a straightforward chronological club … at least , from his view . Where thing get idea - bending is when he turn back and experiences case from before in the motion-picture show from another slant . In fiat to keep the story directly , it ’s better to believe of outcome on the timeline as location on a map - and there are three major location that the characters come back to .
The most important date inTenet ’s timeline is " the 14th " ( it ’s never set which month this refer to ) . This is the potential doomsday , when Andrei Sator plans to entomb the Algorithm in social club to post it back to the hereafter , where it will be used to put down the yesteryear and present . Three major event in the motion-picture show all unfold on this 24-hour interval : the beleaguering of the National Opera House in Kiev that kick off the motion picture , Sator and Kat ’s encounter on the racing yacht in Vietnam , and the final battle at Stalask-12.Tenetboth begin and ends on the 14th ( not include the epilogue ) .
Then there ’s the percolation of Oslo Freeport , where the Protagonist encounters a turnstile machine for the first time and ends up grapple with his own inverted self . The booster has to come back to the Freeport turnstile after Kat is shoot , because Tenet does n’t take control of a turnstile in the timeline until after the Tallinn heist . Inverting spare Kat ’s life by giving her meter to heal from the inverted fastball wound , but also creates the trouble of how to turn around and face the right way again . The Protagonist and Neil practice their old rape on the Oslo Freeport as a windowpane of opportunity to do this .

The last major event is the Tallinn heist , in which the Protagonist and Sator represent a move looting of an armoured truck for find the last piece of the Algorithm . Sator inverts at the ending of the heist , trip rearwards through time and obtains the Algorithm fragment along the way , and remains reverse afterwards - continue his journeying back through sentence so that the completed Algorithm will be in place on the 14th , and he can die his planned death on the racing yacht in Vietnam .
How Turnstiles & Time Inversion Work
At some point inTenet ’s future , a scientist chance upon a mean of invert the entropy of physical object using nuclear fission . This engineering science was used to create a machine shout out a turnstile , which invert the entropy of anything ( or anyone ) localise inside it . That soul or object then start to move backwards through clip instead of forwards . By invert objects using the turnstile , people in the future can engage war on the past - for exemplar , by burying inverted metre capsules that send Au and direction to Andrei Sator . Because they are working with the benefit of hindsight , the mass of the future have a major tactical advantage over the present day . However , clip inversion also has its weakness - specially when what you ’re inverting is not an object , but a human being .
A person who has go through the turnstile is effectively swimming upstream . They might be moving back , but everything else is still moving forwards , establish the world a disorienting and dangerous place for them to navigate . Even the air travel is unbreathable , because it can not lapse through the membrane of their inverted lungs ( the only way they could " rest " normal air would be to blow O out of their pedigree and back into their lung to reform as unfiltered air and then be exhaled - which voice like a immediate and unpleasant way to die ) . The rut transfer of fire and ice is also inverted , which is why the Protagonist being absorb in flames causes him to meet hypothermia rather of burns .
The turnstiles inTenetare establish on a hypothesis in theoretic physics that was proposed by Richard Feynman and John Wheeler . To recap a slight Physics 101 , an negatron is a particle that hold a negatively charged cathexis , and a antielectron is its antimatter counterpart : a particle with the same mass as the negatron that holds an adequate - but - opposite positive charge . Electrons and positron are mirror images of each other , and it ’s traditionally understood that they ’re two different case of subatomic particle . However , Feynman and Wheeler theorize that what we perceive as positron are actually just electrons that have reached a dot in prison term where they turn around , and are now coming back the other way with their charge invert . This could explain why electron and positrons have the accurate same mass : they ’re the same physical object .

( Wheeler also come up with another theory , take to Feynman excitedly in a phone call , that there ’s only one electron in the integral universe , and that all of the electrons and antielectron we see are really just that same electron bouncing backwards and forward boundlessly through spacetime . Do n’t be surprised if that ’s what Nolan ’s next movie is about . )
Neil name - swing Feynman and Wheeler , along with their theory about electron and antielectron , when he and the Protagonist talk after their first time perish through the Oslo Freeport . It ’s a cast-off logical argument and the Protagonist directly lampshades how complicated the theory sounds - but the audience really just learn a rendering of it play out in front of their heart . In the Freeport conflict scene , when the Protagonist first sees the turnstile and a mystical reverse antagonist burst out of it and start up defend him , he believes that the human beings he ’s fighting is just some faceless enemy . by and by in the film , however , it ’s revealed that the masked human race who came out of the turnstile wasalsothe Protagonist . We ’re not determine two multitude fighting one another , but the same man fighting himself . In this dramatic reenactment of Feynman and Wheeler ’s possibility , the forward - go Protagonist is an electron and the inverted Protagonist is a positron .
Why Inverted People Can’t Touch Their Past Selves
One of the many dangers of inverting is the risk of unexpectedly happen your past times ego . This is a common feature of fourth dimension change of location movies , and character are typically warned against it because they could end up changing the future . InTenet , however , the danger comes down to a individual intelligence : " annihilation . " In purgative , disintegration bear on to a reaction where a corpuscle ( like an electron ) collides with its antiparticle ( a positron ) . When this happens , both the atom and its antiparticle disappear and energy is released . Therefore , an inverted somebody interacting with their past self could cause both versions of that mortal to be wipe out . This is why Tenet ’s inverted agents have to wear protective geartrain .
This precept of disintegration is also what make the Algorithm the ultimate doomsday weapon . The current state of affairs inTenetis that the Brobdingnagian legal age of the world is experiencing time as normal , and only a few objects and people in it are inverted . As long as those inverted objects and people do n’t interact with the forwards - moving version of themselves , they are safe . However , the Algorithm would invert the entropy of the entire public . Every particle would be converted into its antiparticle and start out to move backwards in sentence . The moment that happened , those particles and antiparticles would collide , result in total annihilation . Not only would everything in the human beings cease to exist , the ripple effect through time would mean that it never exist in the first place . This , of course , top to the granddaddy paradox .

The Grandfather Paradox Explained
The grandfather paradox is one of the most famed logical problemsassociated with meter travelling , and it boils down to this : is it potential to go back into the past and defeat your own granddaddy ? It creates a paradox because if you killed your own grandad , you would never be born , and therefore you would n’t be able to go back into the past tense and obliterate your own grandfather , which means your grandfather would dwell , which means youwouldbe born after all , which means you could go back into the past tense and bolt down your gramps etc . When the Protagonist ask Neil what the result to the paradox is , Neil respond that there is n’t one . However , their future descendants believe that it is possible to kill granddad ( i.e. annihilate the past times ) without the resulting worldly Big Bang destroying them as well .
There are a few proposed solution to the grandfather paradox , one of which is the multiverse theory : by killing your grandfather , you would produce an substitute timeline in which you were never comport . However , the version of you that committed the murder would continue to exist , because the timeline that you come from would still be intact . Neil ’s mantra of " what ’s occur encounter " is an expression of faith in another response to the grandfather paradox : that the being of a granddaddy in the first place mean the design to pour down the grandad must have somehow fail . Sure enough , Neil and the Protagonist remnant up successfully averting the next antagonists ' architectural plan to kill their ancestors .
Temporal Pincer Movements & ‘The Middle’ Explained
Tenet ’s concept of a time state of war think usher in struggle tactics unique to defend across time as well as space , and one tactic that ’s used several clip is the " temporal pincer movement . " In a traditional pincer movement , an regular army is split in fiat to attack the enemy on multiple fronts . The goal is to envelop the enemy , putting them in a vulnerable position with no manner to back out . A worldly tweezer cause also snipe on two fronts , but in time rather than outer space . One team experiences the battle in normal clock time , report everything that happens to a second team that ’s on understudy . The 2d team then reverse via a turnstile and fire from the diametrical direction with the welfare of the first team ’s knowledge .
Sator use a worldly pincer bm during the Tallinn armed robbery , which is why the supporter ’s attack to trick him with an empty guinea pig fails . The Sator that he come across sustain Kat hostage in the car is invert , while the ahead - moving Sator is waiting by the turnstile with a tuner , hear to reports about everything happening on the highway . That ’s why Sator counts down ( or look up , from his linear perspective ) using his fingers rather than by utter : anything he allege would come out backward . When the Protagonist throws the case over , Sator already know that it ’s empty .
Tenet ’s soldiers apply another secular pincer movement in their assault on Stalask-12 at the end of the flick . They are separate into two teams : Red Team , who are moving forrad , and Blue Team , who are inverted . The entire engagement bring place across the span of 10 instant , and both teams have the welfare of the other squad ’s cognition of what bechance . This is how , for example , they are able to contemporise the destruction of a construction precisely midway through the conflict . The effectiveness of Tenet ’s worldly pincer movement is neutralized by the fact that Sator ’s homo also have access to a turnstile , and therefore have both normal and upside-down soldiers in the field . However , Tenet ’s end is n’t in reality to gain the fight , but to make it look like they ’ve fail while James Ives and the friend habituate the conflict as get over to in secret remove the Algorithm from its tomb before it ’s buried by the explosion . Sator will die think he ’s won , but the future antagonists wo n’t get their hand on the Algorithm .
After the battle - as Neil resolve to reverse again so that he can go back , unlock the gate for the Protagonist and sacrifice his lifetime to economize him - he reveals that he ’s actually roll in the hay the Protagonist for years . The Protagonist created Tenet in the hereafter , recruited Neil , and set up what is in reality a far gravid temporal pincer motion design to stop the Algorithm from give-up the ghost off . As Neil explains , the end ofTenetisn’t actually the end of the war , but the eye of it . With the crucial struggle won , the Protagonist now has to apply his noesis of how things played out to set in movement all the things that enabled them to succeed : from founding Tenet , to sending Neil back to help his past ego .
