You sir just explained TENET without spoiling a single scene. Legendary stuff.

Beautiful, I was gonna show this to my buddy before watching the movie, but he said we've watched this together before...

This is the best explanation of Tenet on the Internet

Nolan: Professor Trying to Explain A concept in Class PhDeng: Friend who explains a concept the night before exam

This is the best explanation of time inversion on the internet. So beautifully explained. The end story explains the entire movie without even giving a single spoiler. This is amazing.

i also think that the act of rewatching Tenet is like a subtle interactive / participatory experience within the context of time inversion. watching it the second time made me feel like i went through the time inversion machine as well, now armed with new knowledge... understanding that what has happened, happened. that's just me, maybe :) i just liked the movie

Really nice explanation, the diagrams are very helpful. But I just realized something I haven't seen addressed yet, which is a consequence of this time inversion physic model: if we aren't inverted we can't kill anyone inverted! The reason is that the inverted person must always exist up to the point they reversed their time. So anyone you see moving in reverse cannot die! By the same logic, if you see the reversed person heading to a sliding door, you also can't kill the non-reversed similar person that's simultaneously heading to the other sliding door. The only thing that can happen (as showed in the film) is to unkill an inverted person - ie: you see a dead body on the ground, he rises as you shoot a bullet that goes through him, and then he carries on his inverted live. Once he raises back to life, he can't be killed, it doesn't matter how hard you try. Obviously, the reverse also happens - an inverted person can never kill a non inverted person, in their perspective they can only unkill them. The irony here is, in a fight between you and an inverted person, even though you know you can't kill the other person, you can be killed! This is because each person sees their own time going forward (and you may die in your future) but you see the other person's time going backwards (and it's impossible for them to die at a time previous than now). So while you're fighting, you know you may die, and you know you can't kill the other guy. Unless the other guy is you, and you haven't experienced the other side of the fight yet - in that case you know you can't die, because you still have to fight on the other side. Really weird logic that comes out of this!

This is like when the teacher goes over the example problem and you’re like, ‘oh that’s easy’. But then you get to the third homework problem: ????????

plot twist: Tenet was inspired by this video

That story at the end was deep. Hit me hard!

That story in the end should be made into a movie!

this is the best explanation so far.

These "time folds" definitely help a lot, especially the directional arrows. Would love to see some Tenet plot diagrams like this, at least per certain scenes

Okay. Now I will have to watch tenet again for the 5th time

Best explanation on the internet! Thank you. Story at the end was beautiful too and ties nicely into the film ;)

The best explanation of time inversion from all youtube videos

I love the ending because it actually relates to the movie. I don’t want to spoil it, but it’s amazing, and soooo glad you included it

This is the best explanation I have seen so far after searching endlessly

Those last few seconds hit the most Thank you

i decided not to watch TENET since many reviews said that I was very complicated, I gave this explanation video the last chance, and booooom, that was perfect especially the story at the end. i am ready to watch the film right now :)

i think this guy is Christopher Nolan himself 😂, he explained so well like he made tenet movie. thx mate

Perfect breakdown of how Nolan's invertion works. Now I wanna watch the movie a 3rd time.

I must have watched tons of Tenet explained, but this is the best one. I just got the 4K blu-ray. Can't wait to be blown by it yesterday.

mind blown 🤯🤯... best explanation out there.. this guy is a genius... been trying for days to understand tenet... i was just about to give up when this showed up in my recommendation... thanks a ton!

6:40 Wow, I never got that.

(MINOR SPOILERS) IMO, the difficulty in understanding this film wasn't the character inversion, it was the inverted objects interaction with the non-inverted world. For example, the bullet holes in the freeport glass made by inverted bullets. Does the movie imply that these holes existed from the moment the glass was made? If not, when do they first appear? Similar but different problem with the cars on the freeway. How did the (non-inverted) Saab get to the point of being upside down on the freeway in the regular world?

FINALLY, someone with a really good way of breaking it down. You are the only one giving the explanation I have seen that has made the clear distinction that when inverted you are not getting younger [which for some reason other people think]. It is an inversion of perspective and your "forward arrow" when contrasted to the rest of the world. Thank you so much for this. I am gonna be using this to help explain it to friends in the future.

Best explanation I have seen! On a side note, it seems to me that time inversion is best for short hops or for a younger traveler. The *speed* of time never changes, either forwards or backwards. So if you spend DECADES formulating a great friendship, you'll have to spend DECADES getting back to its point of origin. That's years of avoiding inverted air and living in containers. You would have to re-invert to resupply, but that only makes the journey even longer.

This video is underrated.. Thanks for the explanation

I teared up at the story you told at the end. Beautiful.

I've watched an embarrassing number of videos trying to understanding this movie, but all I really needed was to watch the last 2 mins of this one. Unreal. Truly, I thank you!

That ending twist though

Now I finally get the inversion thing

Brilliant! I've watched many explanations and scene-breakdowns on KZfaq, but yours is the first one to make COMPLETE sense, especially of how sometimes people just vanished. Thank you very much indeed! ☝️😎

The Time Arrow diagram is excellent. Explains all the things !😁

The ending of this blew my mind. Great story! Amazing explanation.

That final story was so cool. I expect that you invert yourself to go and save your friend but then it turns out you're the one who shoots your friend. You are the man with the gun. Wew lad

That story at the end...man that was great 👍

Amazing video ! 2 years i've been trying to understand the mechanism of Tenet and you just sum it up in a 12min video. Incredible work, the story at the end is just wow !

After watching several videos this is the best one explaning the movie. Thank you very much!

This is the best explanation! I just watched the movie two nights ago on Netflix and was confused like hell. But what made it infuriating in a good way, was that I wanted to understand it. It was very well executed, but I couldn't get over how one character could be at so many scenes at the same time.

Brilliantly done! This simple explanation manages to explain the toughest plot twists in TENET! nicely done.

If you haven't watched the movie and don't want spoilers then please stop reading this comment in 3, 2, 1, HERE !!! ------------------- Otherwise, Wow !!!!! This video does it !!!! Brilliant explanation . Understanding it and the story you gave at the end actually made me feel less bad about how the movie ended with "you know who" dying at the lock pick scene during the final mission. I can't wait for my past self to watch this video for the first time and feel this good again.

This is the best explanation of tenet mechanics.. and the story at the end made sure you understand what happens between the Protagonist and Niel 👍🏻👍🏻👍🏻

At the very very end when 'you' go back in time forever...well, you won't keep going forever, but rather until you die. So that means at some point in the normal timeline, people have the opportunity to watch a dead body begin spontaneously forming on the ground, then compose into a really old man, then the old man gets up and starts walking backward...

Damn!! I was going through internet trying to find an understandable version of time inversion. Man u r a true genius. Guys like u make the best teacher. Thnx for the efforts ❤️

Thank you for taking the time to make this video! Great content!

This was the first video that actually made a semblance of sense explaining this movie. I still don't fully grasp everything but that's not a problem with this video. This is very well explained. Thank you.

Best explanation and portrayal of time inversion in TENET of all the videos out there. Simple with great visuals and explanation. Thank you!! What I still don't understand is the effect of when you are inverted and you interact with your inverted self. The movie says you would be annihilated which makes sense but it doesn't happen when the protagonist fights himself. I feel that any direct interaction between an inverted and uninverted body would create a loop and stop existing.

This is a brilliant explanation! With a twist at the end!

This is honest to God the best explanation I've seen. The whole uturn analogy and seeing the timelines drawn out really helps. For the life of me I couldn't understand why people would disappear from others perspectives, or how there could possibly be three of one person at any given time. But now it makes perfect sense.

That last scenario *totally unrelated with the movie* make me cry again

Thank you for the excellent video, sharing it now. I was finally able to watch tenet just now and luckily found this video! Huge help for understanding the brilliant concept Nolan imagined!

This will help a *lot* of people who actually hated the movie because they didn't understand the Uturn. Nicely done and thanks for sharing. cheers.

Best explanation of tenet ive seen ! Many thanks 👍🏻

What about the scene in tenet where normal protagonist (un inverted person) catching a bullet (inverted gun), who actually shooting that gun, when they start founding that weird bullet and how the hell they know the protagonist is a man who gonna pull the trigger

Wow. This is so weird. I've recently had so many complex questions that have been absolutely mind-bending to me, questions that couldn't be answered by tens and tens of posts & videos, but then there is just that one post/video that answers it with absolute ease. This video literally answered how inversion works for me in 12 minutes, yet I spent probably over 2 hours reading posts and looking at videos to get a grasp on how exactly it works. Thank you!

Love the last example.. Throwing subtle hints. Great explanation to the time inversion concept

Very well done! Clear and concise and easy to grasp. You should consider using this sort of presentation to explain some of the more complex scenes in Tenet, like the final battle and the freeway chase. There are other overviews available but your flowchart and perspective based view is the best format demonstrating the complexities of time inversion I have seen!

By far the best explanation I've seen. It's such a complicated idea to show visually but you did it!

If I was ever inverted, my mind couldn’t handle it cause I’m always indecisive, I feel like if you were to go through that machine you’d have to have a focused goal in mind

This is by far the best explanation.

Of all the explanations i saw this is the most convincing one. Nice work bud👌

Literally the best explanation out there. Kudos

This explanation is amazing! Thank you!

Wonderful explanation.. Nobody can explain better than this.. How simply explained such a complicated plot.. 👏🏻👏🏻👍🏻

One of the best explanation about Time Inversion. Especially last example of friendship was just awesome. Thank you. I had to really slow down the time :) to understand it but now finally I get a good grip of the movie.

I've been searching for something as clear as this video for days... thank you so much!

What an excellent way of explaining the concept. It was frustrating not being able to figure it out earlier.. Still not there 100% but getting closer - thanks

Damn this makes the interrogation scene in the turnstile scene more understandable. Thats why the soldier said, "saito went to the past"

This really is the best explanation I saw yet. 👍

Fantastic explanations. Great job. Thanks 🙏🏾

God sent person to explain this to us. Kudos

Still in awe at this, thank you!!

I got goosebumps at the end man. Fantastic stuff. I’ve already seen it btw hence the goosebumps.

Thank you! This is the best explanation. Very basic but so many other explanations skip the basics.

Thanks so much for this explanation. I was trying to figure out why a mask wasn't needed and your explanation of 2nd inversion explains it!

Of all the videos trying to explain inversion, this one is the best.

By far the best explanation!

I watched this video again and the ending is such an exciting cliffhanger! Super nice video

Superb, clear video. Really well done

Me: Proceed Watching Tenet Explanations. After Me: Getting Confused. Then Me: Decide Watching Tenet.

Thank you this video definitely helped me with the whole confusion about the movie "TENET."

This is great explaination with clarity.

best video on tenet ever. I don't know how you made it spoiler free. Do you have Nolan's number or something?

Great explanation. Big clearance of many problems I had in understanding Tenet.

the best explanation, thank you

Well explained ❤️best example for time inversion concept ❤️❤️🔥🔥🎉🙏🏼🙏🏼

the best explanation from far i think.

Like everything in CS, I need a guy on youtube to explain it to me. Best explain ever.

the last part is beautiful.

Can’t wait to watch this video yesterday 🔥🗣️

Best Explaination about the movie on Internet!

Great way of explaining thank you!

That time flow thing really helped to understand it thank you!

Brilliant explanation!

just amazing.... so deeply explained... thanks .....

Excellent 👌. Expecting more such stuff from u PhDeng. 😃 Eagerly waiting. Good luck 👍

Very nice explanation mate! Genius...! Hats off ^^

Extremely clever video, thanks so much for that!
