Discuss the physics


So lets say I am a reversed soldier and I shoot a person in the heart with my reversed bullet. As I go about my business for hours or years, is that person dead with my reversed bullet in their heart? In the movie, that person would see the bullet coming out of them and going back to my gun but not until they get to the point when I shoot. So they should be dead and suddenly alive? What if I stayed revered until their birth?

No reversed things should have been able to interact with non-reversed things at all.

They have a device that causes it. Problem solved!

That doesn't address the question at all.

reply

Didn't you watch the movie? It happens/happened exactly as depicted because they have devices to make those reversals. That's all the logic the movie offers. Now, Tenet being a convoluted and illogical mess is something entirely different and a reason it flopped badly.

reply

That is, indeed, all the logic the movie offered.

personal perspective: the physics is hilariously bad in this movie, even though I LOVE the movie. They did a great job, making it seem to make sense and WORK for this story, but there are a zillion easy flaws (even based on faked physics of this concept) to really let this work -- unless contained WITH IN the universe of THIS narrative. Not even going to list them. There's just too many. Atomic decay time/direction, adjacent structures touching etc... anyway....

Due to these faults/holes, I don't feel an effective discussion about the physics can even take place. We don't have enough technical information to go on, other than "well, it worked like that IN the movie".
The first backwards bullet shot is SUPER COOL and confusing at that point, but kind of unravels the physics and time direction. But, like I said, I can go with suspension of belief and just enjoy it as unique and fantastic entertainment, which it was for me.

Even the "You had to have dropped the bullet" part didnt really work, because they just show him a second later undropping it. When did he drop it? Why was she able to undrop it at that exact "Time"? Yeah... it doesn't REALLY work but it's a lot of fun. Light Sabres don't really work either, but that turned out okay. :) Many, many, MANY physics things in movies "don't REALLY" work, but it is all good, and I would not have it any other way. Movies need to entertain, not be real. Those are boring documentaries. :D

One thing Nolan kinda does that others do not, is TRY to bring things to us in our real world as if they COULD BE real. Unlike over the top crazy powers in super hero movies, Nolan keeps it under the top and ALMOST relatable as real... example: Batman living in a NORMAL city, driving actual vehicles instead of crazy shaped clown cars and living in weirdo looking city.

Beyond all that, it IS science FICTION, so I absolutely love the ideas, how they were presented, and will buy the Blu or 4K disc asap.

I enjoyed a few of the action sequences very much (like the self fight) but the problems with the interaction of reversed troops with non-reversed objects is too big of a problem to overlook. I understand the less-is-more thing with explanations but that doesn't fly with me in a story that gets into the details on all else. If this was a 30 minute Twilight Zone episode that left out the efforts to explain the physics, I could have excused it a little easier. Their big plan was made to seem like it was brilliant in its difficulty to grasp. Turns out that it simply doesn't work. Not even within the rules they establish. SPECIFICALLY not within the rules they establish.

I can suspend disbelief but there is a ceiling.

reply

hehehehehe yeah, I totally get and respect your position. :)

I'm just letting it go. "How the heck can a light sabre ever work??" "Because we see it work in the movie" :D

I do think Nolan pushed the envelope of what is acceptable to audiences too far, with all the comments about not following it. There is definitely a limit to stories that can work. Past that line, and it is david lynchian "make up your own interpretation" which is silly to me, but some enjoy that, and that's cool.

Just hope he hires better dialog mix engineers for the next one!

reply

That's just not a valid comparison at all, I'm sorry to say. You can easily suspend disbelief for a lightsaber, because they are not inherently confusing or out of place.

We know what swords are, and a lightsaber is essentially just a sword... made of light. The bizarre and illogical mechanics behind this movie are something we are not familiar with, and make little sense at any level of inspection.

reply

A shame. The idea is interesting but didn't quite pan out. I like half of Nolan's efforts. This one was half baked.

Regarding the light sabres: They didn't try to explain them so we are left to fill those gaps in with assumptions about a technology advanced beyond our understanding. In Tenet, they say "Here's what's happening" and then "ERROR." They established rules and then tried to hide violations behind layers of complexity.

I wanted this to work. I loved how it looked and the ideas are cool.

Lightsabers probably use LASOR technologie or something. Also: hand waving.
