Can we reverse entropy? Quantum physics behind Tenet

In this video we explored the quantum physics behind Tenet.

Reversing time is always deemed impossible. However, the equations of motions actually work perfectly fine no matter time is going forward or backward. This suggests that time inversion is only restrained by the second law of thermodynamics, which states that entropy can only increase but not decrease in an isolated system.

What is entropy? Can we reverse entropy? Why can't we catch a bullet in real life? All your questions about entropy will be answered in this video.

Bro this was an awesome and concise explanation that allowed a layman like me to understand it.

[guerney]

There is yet insufficient data for a meaningful answer

This channel is too small for such a good quality video. Will sub

I like these videos but they feel too short. Keep up the good work though

1:16 why is the case moving with the bullet 🤔

So on that last part can we technically reverse entropy in real life just by cooling rt air since that’s basically putting it back in low entropy?

Dan Simmons, in his sci-fi Novel series Hyperion Cantos, already mentioned things like anti-entropy, things travelling back in time, etc. I think Nolan may be aware of his Novels. So Nolans concept is not unique.

interesting so I guess if we draw the whole into pseudo physics realm...but inverting the future in the future, and causing reverse entropy or reverse disorderedness they are increasing the orderliness of themselves while increasing the disordering of the past. Hence the whole concept of the ice melting and freezing again. Entropy always increase due to the increase in chaos around the world. But what if that was reversed....heat becomes cold eh?

Very good video overall but @3:00 you are incorrect on reversing entropy. Turning on an air conditioner or putting food in a refrigerator does not reverse entropy, it merely slows it down

1:13 you were wrong.
Lets forget the velocity
cauz if you know the exact position of an object then you can't know whether the object is in rest or motion and in your video you boldly said that both position and velocity of bullet can be know for a exact second which is exactly wrong.

according to quantum mechanics, if you know the position of a particle then you don't the it's state of motion for eg: there is a apple on the top of a moving car, your vision saw the apple only and you didn't saw the car. So, at the very second when you saw the apple, let's pause our example, when you saw the apple, you saw an apple which is it at rest and you saw that it was a bit farther from you in a road but it's wrong, at that very second you got the position of apple right but as the apple was moving along with the car, you couldn't clarify it you, if apple is moving then it doesn't have a position and if apple has a position then it can't be in motion and it needs to be in rest but in reality the apple is in motion so it just forms a kind of paradox and now connecting this to what you said on 1:13, you can't say if it's moving or not and if you can't say if it is moving or not then how can you say that it has a fixed velovity
