Video games have this issue. Basically the computer checks the object in one frame and the speed of it. If it calculates that where it should be in the next frame is free of obstruction, that object can pass through barriers.
To fix this, we can do a few things like increase the ticks/ frames per second but that increases processing requirements so just making the barrier thicker is usually a good solution. But there's other methods that can cause unexpected results.
Great comment 🤝
So THAT'S why hitting objects really fast in games makes you clip through them. I always assumed it was something like this (the object moving before the computer realizes it's collided with a hitbox.)
Came here looking to make sure someone called this out. Most quantum phenomena reinforce the idea that our reality is a simulation imo lol
A perfect example of this is using the Backwards Long Jump in Mario 64 to build up enough speed to clip through doors or walls.
The game checks the player's position, facing angle, and momentum, and uses that to figure out where you're going to be on the next frame (technically every quarter frame due to how sm64 runs its collision checks*) so by being on one side of the wall one frame, and having enough momentum to be on the other side of the wall on the next (*fourth of a) frame, you will clip straight through the wall, door, ceiling, etc.
@@SleazyDutcham This is kind of a catch 22 though because, a stable reality should be able to be simulated right? I don't know if it's possible to create a reality that can't simulate itself.

"There is a non zero probability"
"So you're saying there is a chance"
It's improbable ,it's all about the probability function of the electrons (it has a small value beyond the barrier)
Yes
Saving this line for other circumstances 😂
@@mayankbhaskar1654 so how come the number of photons making it through the glass is consistent and calculable? is it not a random probability? do the same areas/shapes of photons make it througj?
@@LoonieMoony a huge number of photons are there
The probability of tunneling is low but constant and can be calculated thats why on every area the image is consistent
Secondly if you look at the image it will appear a little darker than the image we saw at first that's because the intensity is lowered due to less number of photons making it through
Please make a longer video explaining this in detail.
Wave function describes a probability of the particle being found at a given location. It is a distribution in space, so it says at point X the probability of finding the particle is P(X) and at point Y the probability is P(Y). If you put a barrier somewhere that interrupts the probability distribution, there is still a small chance that the particle will be found on the other side of the barrier. You can think of it "leaking" to the other side of the barrier. In classical physics, the particle has a definite position so it will definitely only be on one side of the barrier.

One of my favorite things about physics, that the possibility of something or someone hitting something so hard they just pass right through is not zero

Well...as explained in this video , any atom can bypass a wall , since a wall is just a big amount of atom , and an object is also a big amount of atoms
However , atoms of a wall and humains are linked to each others , the link cant be broken , unless you link it back later
Linking back each atoms the way they were linked each others...thats the big problem
Im not good at atoms since i stoped studying them at 10 years old , but i guess thats where the teleportation/time travel parts are a problem
However , idk if its true , but ive seen somewhere that someone made a mousse time travel , i think it died
But anything that isnt as complex as humans can bypass some walls , light can bypass glass wall , water can bypass sponge wall , cats can bypass logic wall lol
However , while humans are hard to teleport , informations such as our brains one are easier , right now our words are bypassing a distance wall , and our voice can , our vision can , our ears can , and once our brains are connected to a network machine (such as virtual reality) , we will be able to bypass any walls we want , even time , at least virtualised time
So its not that far , if only scientist were allowed to experiment on living brains

Remember this is just an *analogue* for quantum tunneling, not a demonstration.
His finger touches water on the edge of the glass which has an in-between index of refraction between the air and glass which no longer causes the total internal reflection (and the light goes through)
It should be mentioned that In TIR situation there is small leakage of light field tail called ‘evanescent wave’. Interestingly It is actually traveling on the glass wall, not propagating away. Its boundary is hard to be defined but we can say Its thickness is about wavelength. When someone gets close enough (about 500 nm from the glass wall) to the evanescent wave, it can escape through his fingerprint: evanescent tunneling. That’s a quantum tunneling. The real limitation of this demo is that the barrier should be about wavelength of light but in this demo the barrier doesnt exist because he touched.l the glass. obviously no one can precisely maintain subwavelength distance with just bare hand unless you are a nanostage. More accurate demo imo is a beam splitter which is a sandwitched prisms glued with a thin coating. Very interesting video tho.

It seems like but it is not. In quantum land it would just be 'I'm Tunneling' Which is kind of okay so if you like it go for it.

“How I used quantum physics to get into the backrooms”
"How can you noclip on command?"
"Quantum tunneling"
Boundaries are 1) Finger to air, 2) air to glass, 3) glass to water, 4) water to air. Each boundary both reflects and transmits photons. The transmitted photons are refracted. That means the transitted photons change direction by the refraction angle at each boundary. Pressing your finger on the glass replaces two boudaries with one boudary (finger to glass). This results in a change in refraction angle which allows you to see the finger from a different angle than before. So in ALL cases there are always photons "tunneling" thru the various materials. This means your analog is not a good one because all materials (air, water, glass) always have photons tunneling thru them. You demonstrated this in the video by changing the glass angle with respect to the camera so that the photons were directed either towards or away from the camera.
Ya I thought his “proof” of quantum tunneling was a crock of shit.
I thought the entire point of the video was that you can't just completely remove the air between the glass and your finger, if photons didn't tunnel *through* the thin layer of air then you wouldn't see the finger because the layer is still there
@@truthwatcher2096 The air is not a "barrier" to photons in the classical sense. The reflective effect is _not_ caused by photons "bouncing off of" the air layer (light can travel through air just fine), it is actually caused by the difference in refractive index between the glass and air, but that refractive index is based on the _average density_ of the medium in contact with the glass, which requires some depth.
Even if you can't get rid of all of the air molecules between your finger and the glass, by making the air layer thinner, you are actually _changing the refractive index_ which is why it becomes visible. This does not actually involve "tunnelling" (any more than any other everyday phenomenon does).
It is a neat demonstration for various reasons, but unfortunately, this is really not demonstrating the phenomenon he thinks it is.
What he is showing is FTIR, which is a result of quantum tunnelling.

Thank you! Great stuff!
I just tried it. Never have I been more fascinated for no reason.
The effect you're observing isn't due to quantum tunneling, it's a result of refraction. When you press your fingers against the glass, you're altering the path of light from your fingers, reducing how much it bends, or refracts. This makes your fingers more visible. Plus, you might squeeze some water away, creating an air pocket. Light refracts less in air than in water, so this also makes your fingers easier to see.
I felt like this illustration wasn’t really quantum tunneling but l was looking for someone who knows more than me to explain why. Thank you. Now my curiosity is satisfied.
How is that post under 10 likes and someone who is "quantum tunneling at home" gets thousands.... This world is so leavable^^
He is not even saying its quantum tunneling. He said its a great analogy for quantum tunneling. He even showed in the video that the phenomenon was a total internal reflection.
@infi_3252
He also says "the photons from my finger can actually quantumly tunnel through that boundary layer of air to reach the camera". Even if he did mean it as an analogy, his phrasing is still pretty misleading.
He specifically said "you can actually see a great analog of this..."
Analog. That's a physical/visual analogy.
What's really cool is when you actually do the maths and solve the Schrodinger equation for a particle in a well with a potential barrier and see that the amplitude of the wave function is non-zero on the other side of the barrier.
Ugh! Must've been a Dell.
This blows my mind! That is awesome!
"Quantum tunneling" **Laughs in refraction**
I snell what you're cookin. 😏
💯💯
That's why he said "analog."
Well light didn't reached to the hand because of air gap between hand and glass, but when he used force and lessen the air gap, light reached the hand and bounce back to your eyes. It's just like quantum tunneling, that's why he says analog and yes he says photons 'cause light is composed of photons.
Some of the terms are changed when we discuss reflection, refraction and other things, when we discuss it in quantum level.
I think the finger changes the critical angle, causing less light to reflect making it a mirror

Excellent explanations - Let's discuss Quantum Gravity . Cheers Mate .
Is it really quantum tunnelling, or just pressing hard enough to squeeze out any air so the light doesn't have to travel through the 3 separate media which it needs for TIR?
Basically just trying to make the third layer (air) negligible to the point the only thing the photons are traveling through are the glass and the water (and then the air from the water to the observer of course)

@@chosentonessournotes Ok child, you need to go outside and get some exercise. Someone's a little grumpy. Smh
This isn’t quantum tunneling. It’s called “frustrated total internal reflection,” and has to do with the evanescent wave-coupling of the light between the media. Some sources do claim this is “quantum tunneling,” but I would disagree on the basis that this can be described as a purely wave-like phenomenon, and can be described in classical field theory.
Ok bro
Thanks yo, finally someone does their research
This seems like he’s just removing the air from that spot and putting his finger there. It doesn’t really seem like quantum tunneling at all lol
not true at all this is quantum tunneling but its okay keep misleading people with useless fabricated information🤡
“Frustrated total internal reflection”
Wait that's why my water slowly leeks
This is the best explanation of quantum physics thx so much
refraction and total internal reflection left the chat
Further explanation:
The glass become opaque due to total internal reflection
Because there is a glass to air interface
When you try to press hard you remove air n making it a glass finger interface thus stoping total internal reflection n your finger is visible
But you can't remove all the air some (a few molecules wide) might still be there. Despite this small amount of air between finger n glass due to quantum tunneling photons escape n total internal reflection fails n finger becomes visible
Almost like that's what it's written in the video and this is, as he said, an analogy.

Dark humour
The teacher was half right
0:16 🤯 HE DID IT!
I think one of the core concepts that people fail to think about whenever they look at these quantum level effects is that, at a quantum level, there's a lot of empty space rather than a full solid object to pass through. The seemingly magical ability of one particle to pass through a wall of other particles is actually just the very small chance that all of the other particles happen to vibrate out of the way at exactly the right time so that the first could make it through.
No, you just removed the barrier, photons aren't tunnelling through a thin layer of air, there is no air since you pushed it all out or into your finger due to the porous nature of your skin. Your skin is actually touching the glass directly and it's just as though you had a wet finger because the moisture on your finger allows your finger to touch the glass directly and remove the boundary layer.

Quantum editor
I do all my quantum tunneling at work, thank you very much.
Great explanation
Not if the barrier is "thin enough"; rather, given the potential energy barrier compared to (being greater than) the kinetic energy of the particle, the decaying exponential function describes the probablity of the particle making it through the barrier. For any given energy difference (V-E), and width of the potential barrier, there is a decaying probability of the particle making it a given distance through. I also don't think that the reflection (or lack thereof) is due to quantum effects. I would propose Maxwell's 3rd and 4th laws instead. (Oh, and by the way, your fingers aren't emitting photons in the visible range, they would be reflecting photons that have gone through the water and glass. At best, we emit infrared light due to body heat. And so on.)
I like your funny words, magic man.
@@StuffBySam I like your melons, princess.
In this case, “thin enough” really just means “finite”; the probability only goes to zero in the limit of the barrier going to infinity 🤓

Action Lab, I think you’re a great guy but man I wish you were a little bit more rigorous about how you use terminology and explain things.
For those of us who’ve literally never heard of this stuff, his explanations work well enough.
@@goldiloks08 no, because people are gonna think quantum tunnelling is actually happening, because he litterally said that, while it's not, and it doesn't matter he said it was an analogue, because it was easy to miss and contradicted that statement at the end
@@nerdyfalco408 I didn’t miss that it’s still analogy.
@@nerdyfalco408 nobody missed the analogy lol
@@parthsharma3528 read the comments maybe, it's like split in 50% who didn't see it and 50% who did, but people that actually know the phenomenon KNOW this is not a good analogy
I love the implication that there’s a classical physics way and then there’s the spicier bad boy quantum way
I feel like they just don't know what's really going on at that scale.
@@accumulator4825 quantum physics gave us the microelectronics revolution. The scientists don’t just sit on an armchair and think up crazy ideas. It’s backed up by rigorous mathematical proofs and has many real world applications.
