What the HECK is a Photon?!
Vložit
- čas přidán 15. 06. 2024
- A photon is a purely quantum mechanical object representing the smallest piece of energy (or quanta) for light. Every quantum particle is a packet of energy though, so how do we tell photons apart from electrons, quarks, and neutrinos?

You should have started the video with ''let me shed some light on photons''
Missed opportunity.
Giz FPV lol good one..
Giz FPV. Let me shed some light on photons, photons are things I light my shed with :-)
Do all photons originate from the sun?
Jeff Shanahan. The quick answer is “No”. I’m no physicist but I know that a proper answer could take up a large part of all the comments sections on CZcams. Photons originate from atomic reactions wherever they occur, as well as the sun & all stars. They’re emitted when electrons lose energy & drop down from one energy level to another. Also from decay of subatomic particles such as protons & neutrons. Photons are massless so don’t add to the mass of subatomic particles but are involved in changes of state. I wonder if you know more than your letting on though as your question seems so simple yet is so complex! Ponder your question over a cup of tea & you will feel photons emitted as heat as your tea cools off :-)

Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.
"Thank you."
@@SpotterVideo Interresting..it does make a sense
@@Blameberg Thank you for the kind response. They are very rare these days. Have you ever heard of the Dirac Belt Trick which uses the twist in a belt to explain particle spin?
I love your channel, it’s so educational. Is it too late to ask a question? You said that the human eye does not capture photons separately, so stars fade into space. Does it mean that if we had more powerful eyes, we would see several points in space flashing? If we point a space instrument at the sky, does this happen? Sorry, it's the only part I didn't understand. Would a star that was very distant, the most distant of all stars, still flash from time to time?
Tree frogs can see individual photons and the night sky looks _very_ different to them. They'd see flickering points of light all over the sky. Veritasium did a video about it a long time ago: czcams.com/video/cztocbHiiqQ/video.html
@@ScienceAsylum lmao you just replied on a comment of a two years old video 😂
@@arya1275 better than replied the question two years later
@@arya1275 So did we all
@@ScienceAsylum i can confirm this, the night sky looks awesome and thats why i like astronomy
Honestly, at first I was like, "This guy might get kinda overwhelming and cheesy." but damn dude, you're genuinely funny as Hell and really, really awesome at what you do. Perfect balance of silly, well done jokes and impeccable presentation of content. Bravo! Good show ol' chap :)
Thank you for telling us (at 4:22) that "The human optic nerve doesn't send a signal to the brain UNLESS 9 photons arrive within 100 milliseconds."
6 photons, not 9...
I want sources for this, not a dude on youtube telling me or a dude in the comments correcting another dude.....
I mean, its always just about some dudes telling a story. Like Bible.
@@jonboshears7767 You should be able to find source links in the description 😊
Are you guys thinking about building invisible suite?
"I don't ruin things,I make them more accurate". LMAO!
Love Nerd Clone!!!!
You remind me of someone I used to know. Hope you're doing well, Sutton.
I graduated High School in 1981, I wish you would have been my physics teacher as I learned more in a few minutes that in the class. Your presentation and energy is fantastic! I am pleased that there are educated people willing to share their knowledge with us. Thank you
Everyone asks what are photons but nobody asks how are photons.
How science feels like...
Came with question:
"What is a photon?"
Leave with 3 others:
"What is spin?"
"Why c is equal to that value?"
"What ignoring time/space mean?"
"What is spin?" czcams.com/video/sB1EPGmpzyg/video.html
"Why is c equal to that value?" Coincidence, as far as we can tell.
"What ignoring time/space mean?" I'm assuming this refers to how I said photons "don't experience time or space." Things that travel at the speed of light (like light does) have infinite time dilation and length contraction. It's a Einstein's relativity thing. It also means those things _must_ travel at the speed from all points of view, which leads to very strange effects: czcams.com/video/a9T26ItpcDA/video.html
@@ScienceAsylum hey listen if time stops at speed of light then how the object (i.e. photon) travels as time is topped its motion should also be stopped.
@@ankitthakurankit4764 From what I know, people who actually move at fast speeds experience time as if it's normal, however the difference is when you are observing something else move at a velocity relative to some point (After all it's called, "Special RELATIVITY").
Consider this situation: We have someone standing still, person A, (someone not moving in a reference frame), and a car with someone driving it, person B, at a very high velocity relative to person A.
Person B experiences time as if it's running normally. Person A also experiences time as if it's running normally. Keep these in mind.
However, when person A looks at person B (From the perspective of person A), person A OBSERVES that person B is experiencing time at a slower rate. When person B looks at person A, person B observes that person A is experiencing time at a slower rate too. The reasoning behind this is because relative to your own self, you would not be moving it appears that all other things are moving in the opposite direction you move, therefore, Person B would see Person A moving with a speed equal to how fast Person A sees Person B moving (You need to take into account which perspective basically).
Essentially, when you travel at the speed of light, is it said that time stops but ONLY FOR AN OBSERVER who sees the thing travel at the speed of light.
(There is also the other effect, as mentioned by Nick, length contraction, but I don't believe you need to consider it in your question)
The idea is that whatever your speed is, you'll perceive time to be moving at the same rate (this also includes people in your reference frame who have a similar speed to yours)
I should say that since we haven't moved at the speed of light, we actually don't know what it would look like to perceive the environment (if you can at all), however it's just based on the predictions using Relativity.
@@ankitthakurankit4764 Faster you travel in space, slower you travel in time. Imagine you have a spaceship that can do light speed. If you ride in that ship at light speed, you'll feel like you're "teleporting" from one place to another since time is not moving from your reference frame inside the ship.
Outside of the ship though, it'd look like you're travelling at light speed.
This means, if you travel half a light year away and back, it'd feel instantaneous to you, but to earth, a whole year would have gone by.
@@rtfmpeople sir when i'm travelling at speed of light my frame of refrence will too move with the speed of light along with the frame of reference of ship. Now imagine the total distance travelled by me was a one light year and I'm too moving with the speed of light and covered the same distance of 1 light year so i don't agree with the point you made that for me this time will be less than a one year.
Your animations are getting really good! And how did you throw the torch to your clone self? Do you really have a clone?
Thanks Jade! Practice makes perfect, as they say. As for the flashlight, it took him a couple tries to catch it. Question Clone is a bit clumsy.
Of course he doesn't really have a clone, that's just silly. He's simply throwing the torch to a copy of himself as he would have been in an alternate universe after the duality of all particles is settled. This is a simple party trick that quantum physicists have been doing for decades.
It is simple: the ball that's going down out of screen is other from the ball that's jumping from the bottom of the screen. The first belongs to the right Nick, the second belongs to his clone.
I don't ruin things, I just make them more accurate.
"Bitch Stewie"
Yeah I just replayed that bit for a while. That was awesome, Nick.
Tossing the flashlight done to perfection
this guy is amazing. he makes it all easy and simple to understand and he is active in comments for any questions people ask.
1:40 that must have taken a lot of effort!
Ajay Singh Rathore if i had to guess i'd say the right arm in the labcoat wasn't his arm? Not sure though, cool effect either way!
Learnt more here in 6 minutes than an hour of chemistry period in school.
Wow.
Its very inaccurate though. Photons dont exist before they are being observed/interacting with something, a photon is the energy discharge of a collapsing wave, photons dont move, waves move POTENTIAL photons that will be discharged when the wave interacts with something (the observer).
Very well explained - a definite gift to be able to make this simple series of concepts so interesting to the average joe.... its hard not to watch all of your videos to the very end..... very well produced with the torch tossing across the split screen. Well done Nick!
1:40 - Damn, that was really well done.
A photon cannot be a good Catholic, since it has no mass.
If so how does a clack hole capture it? There is no gravity, space is time warped.
That is correct. In addition, photons are not Holy since they indeed don't have Mass.
jose gonzales Nice job ruining the joke
@@lunatik9696 : What's a "clack hole"?
@G809 GD no my friend your equation states that how much energy can make a given amount of mass. Or vice versa
"I dont ruin things, I make them more accurate" story of my Life.
Remind me not to invite you out anywhere.
Thank you so much for blasting the world with so many educational photons!
Your photons are very enjoyable to absorb and transform into thought.
I love this channel so much 💛
It favors very interesting and insightful thinking. Knowing that the human optical nerve is responsive to, minimum, 9 photons is amazing. We constantly witness electromagnetic radiation; which is something to consider every second of that biological, miraculous, experience.
Hmm, Schrodinger's cat turned into a squirrel... o_O
It is a superposition of a squirrel and a cat.

These videos are brilliant. Really underrated youtuber. Very difficult subject matter as well.
Really great video. I may have to watch it a few more times , you and your clone make a great team, hilarious .
I really love your videos!! I just looked about the optic nerve and it is very useful all the details you give in your videos. You are amazing.

Glad I finally got around to it :-)
I love how you're wearing a Dark Side of the Moon shirt while talking about Photons.
Loved this video! Great job!
By going into the detail, that is exactly how you teach people what something is. I liked in particular how you said "yes, light is a packet of energy, but that description isn't useful". That is gold
I've just watched 2 videos of your channel.
I'm hooked.
You break the physics down to the nitty-gritty: Love your 6mins reductionist take on it.

Oh my! I teach Physical Science to my kids and often I turn to your videos for better understanding. This is one of the funniest and you are adorable; however, I prefer your clone ;). Thank you, for the video
What if photons do not move independently of space-time because they are the fabric of space-time? Like pixels in a tv screen, and only light up when subjected to electro-magnetic waves. Wouldn't that be interesting?
considering photons represent a small section of the electromagnetic spectrum that WOULD be intriguing..
maybe someone can conduct the experiment with different types of electromagnetic waves🤷🏽♂️🤔
This channel, in particular, is really making waves.
I love your humorous in every video!
Q: is there a limit on how much energy a single photon can carry?
like the more energy it has, the greater frequency it is, but up to a limit?
you explain things so amazingly and your hecka funny.
easy on the clone though
Brilliant and funny. Love this channel!
You explained quite a lot. I had to watch this over 10 times. Thanks for the education. 👍
My older videos like this one are _very_ information dense.
@@ScienceAsylum after 4 years, he still replies, that is some serious dedication.
Thank you for shedding some "light" on the subject. :)
Not directly related to the topic of photon, but the 1:39 toss was well edited!
What do you mean? Those clones are real clones!
ikr, it caught my eye
Wubbywub its real
seriously, I played that on 0.25 speed and I can't see anything out of the ordinary
thank you.
Thanks man. Even grown adults benefits from your explanations (when not versed in science). I had the idea that a photon was a particle of light but never really grasp what it rally was. I saw it more of a measurable state of the wave the way it had been simplified when taught to me in high school.
Just pleased to see the precise answer.thanks.
One thing that I never understood and you didn't explain. What is traveling up and down the wave. I know it can't be the photon since that would mean bigger wavelengths of light would travel slower than smaller ones. So a better question would be... What is wavering? What makes the wave? What is the wave?
Mateus Bittencourt it's the eletromagentic field , imagine it just like how a wave travels in water or smthng , the molecules of water go up and down , and the wave is just how we describe the transfer of that kinetic energy indirectly
That picture of the wave is a graph that just shows the intensity of the electric and magnetic fields at a string of points along a line. But remember that the wave is not actually constrained to that line. Also the changing electric field generates a changing magnetic field which generates a changing electric field, and so on, which causes the wave to propagate.
I believe you should have a look at the uncertainty principle
Behold. I give you,...the wave....👋
Amine Aboutalib and gpellmind have given great quick explanations. If you're looking for more, my next video is on quantum field theory.
HARD-WORK IS CLEARLY VISIBLE YOU DESERVE SUBSCRIBERS.
The best about these videos : most of the time, it leaves with facts and not conclusions. which is what science should be about.
01:54, Nick u almost said *'quantum fizzy drink.'* lol I've noticed that u dnt edit things like that out. I like it and adds another dimension to your videos.
A photon is an excitation of the electromagnetic field and travels at the speed of light.
I like this guy way more than Bill Nye
I was thinking about this the other day
😶
L E ,fraud,how so? Or are you just inferring...
@British Observer Gender is a spectrum..
@British Observer Are you serious? You do know people can be born male and female or neither depending on their X and Y chromosomes.
What did I just witness :O. Great work!
the clone glass is one of my favorite, i dont know if it's because of his tongue accent, but his interventions make me always laugh, have a good year, weeks, days, minutes, seconds, photons, etc etc
When you said 10m trillion photons per second I had to pause and go get a sandwich and then come back, my mind still in blown status
Holy cow! How did you get the torch throw so seamless? Very impressive.
I THINK I know now...
When the throwers’ hand dips just out of frame for that instant, it’s actually a different hand that does the toss. Bravo! Just as brilliant as your wonderful content!!
Right idea, but it’s actually even simpler. The throwing hand is not his the whole shot. Look carefully before the toss. The hand is feminine. Mrs. Science Asylum!
Funny explanation and very helpful! Thank you! 十分谢谢！
Great video!
Okay, how did you split-screen a flashlight toss?
Let me introduce you to CaptainDisillusion. The flying flashlight is not real but a simplified guiding image, and its obvious if you watch it frame by frame. Its no coincidence it happens in front of a simple blue colored background. Neat trick, but very easy to spot. Now Im serious go and check out this Captain Disillusion guy he is the authentic expert on VFX and he needs to be more popular.
someone threw the flashlight from the bottom of the screen
CraftyFOX, I can assure you the flashlight is not added in post. It's a real flashlight.
Yea, I watched it again and it's not, but it somewhat looks like that because of the camera blurr. The smooth background did not made it less suspicious though.
Could you make a detailed video about the double slit experiment? One where you explain the physical methods used to observe the photons passing through one slit or the other etc. Because a lot of videos talk about how these particles behave differently after being observed but skip what that actually involves... a whole video on that weird concept as a whole would be awesome anyway. Just with actual details of how things are done in the experiment.
You make my brain hurt in the best possible way, and you know of course that your clips need to be replayed and enjoyed again. I do understand that Einstein said that repeating the same activity and expecting a different outcome is insanity. But every time I replay one, I still snicker the same, but I actually become a little smarter. How scary is that?!?
Glad you enjoy my work. Thanks. (even if it is such an old video)
great content, got my sub my friend :D
I watched this for 21 seconds and I'm loughting like crazy :)
*YAY A SQUIRREL WAS IN THE BOX*
Awesome vídeo, thanks for explaining my doubt.
This was a really good video!!!!
That was the best definition of a photon I can remember seeing. Do we have detectors that can sense photons in the black portions of the night sky? Would they sense intermittent arrivals of photons?
I'm waiting for someone to convince me that photons actually exist. It's a crazy idea.
Oh yes, absolutely. In fact, there are photons in the microwave range coming from _all directions_ (including the black parts of the sky). It's called the cosmic microwave background and it's taught us a lot about the universe.
@@ScienceAsylum that's a great succinct description of the cosmic microwave radiation..... All you read is its being detected and then you think microwave ovens or radio transmitters!! 🤔😊
@@ScienceAsylum why photons always travel in speed of light...why speed of light is a constant number (3*10^8 ms-1) and not any other value...what are universal constants? ... Why they are constants in Every part of the universe
This ia really an asylum. Everytime I leave very much confused. Details, details! Good work mate!
Interesting way of discussion.👍💐
SHEESH! These early CZcams edits (you going from one side of the screen to the other). Nostalgic.
Edit: Maybe I'm over thinking. But, what 'colors' would we see if we could see in every other light spectrum? Or what if we had 12 cones like that mantis shrimp?
1:40 damn nice edit man
Could you talk about the double slit experiment and the delayed choice quantum eraser ?

Great explanation.
I was looking for some explanation about photons and light since yesterday, and to be sincere, you video was exactly what I was looking for
Glad it was helpful! 🤓
I feel like this is three years oh middle school science packed into one video... and it makes sense!?
So if a photon has the inability to experience space or time, when a photon approaches a black hole what does the photon experience?
It enters to a different time line which doesn't exist for us
@@shovanray3557 then how photonsphere is created outside the event horizon?
@@priyas5637 It's actually the Star which is technically being swallowed by the Blackhole.
@@HardikKundalwal o thanks for answering now I got it
@@priyas5637 Its fast moving matter creating heat by friction as it orbits the black hole before being swallowed. Heat up matter enough and it becomes white glowing hot.
Me: Any particle that has a whole number valued spin is a force carrying particle (or atleast I heard so)
Also Me: A photon has a spin of 1
Question Clone: Wait, won't that mean that a photon carries a force?
Does it?
The photon is the force-carrier for the electromagnetic force, but it's a little more complicated than you're probably imagining. _Real_ particles aren't force-carriers. _Virtual_ particles are... and those don't really exist. They're just a math trick.
Great video 👌
