At the end of videos like these, I always feel like I've learned a bunch of things and nothing at the same time
Well, at least we saw a bunch of cute little birds just standing around.... in a nutshell. :D
Yes i feel like i cant explain what i learned properly
Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metres to radio waves measured in metres.
Just take notes on important point
Paradox of Learning 🙂🙃💁♀️
Learning any physics stuff always just brings up so many more questions
Yeah because relatively speaking we know almost nothing.
Welcome to the infinite complexity of reality.
It always makes me happy when they say, 'In a nutshell'.

Can we rename flashlights to photoncanons? It sounds cooler and is technically correct...
it's me YES
Nah save that for the actual future photon cannons lol
if it were literal. People in clubs are massacred
cool
it's me or plasma beams!
What's really mind-blowing is that from the perspective of a photon, it hits its target of absorption or the universe ends as soon as it's created, since it doesn't "experience" the passage of time
Exactly. Not to mention that the universe is flattened into a single plain perpendicular to it's velocity which is weird if we consider the universe to be infinite.
From it's prespective it measures it self to be moving at a speed of c NOT 0!
Also, everything else for that photon is going to move at the opposite direction in the speed of light.
Even objects with mass, meaning that they are going to have infinite kinetic energy.
It truly buffles me to think how would it be like if we could run at the speed of light relative to the earth for example.
the photon doesn't "experience" anything. While I recognize you're using the term more metaphorically, the fact is that, as far as we can tell, to experience anything requires a minimum infrastructure. That infrastructure couldn't operate coherently at the speed of light.
Maybe it doesn’t experience time because it is a just a vibration of space, time.
"What is light" baby don't blind me
Don't blind me
No more
I just left a comment referring to this song lol
hhhhhyes
That's what I'm expected comment, lol :D
am i the only one who pressed "no more" thinking it would show more? yes? ok... just checking 😂
I actually expected I would see a comment like this, and that's actually why I started reading the comments, to see if I could find one. I thought it would just have changed love to light without changing anything else though. But I think a better execution would just be "What is light?" followed by 4 new lines, so you have to click *Read more* to get the punchline.

Yeee
When you think about it , we never see things immediately , there is always postponement that depends on how much time needed for the light to touch the surface of the thing and then reflect towards your eyes , but we don't feel this postponement because the time needed is just too short for our kind to notice it , however the longer the distance is the more noticeable it becomes , take for example the dead stars that are hundreds of millions light years away from us but we are still witnessing the light that is still travelling through the universe carrying the star's image .
It's like watching a livestream of match through an extremely slow internet , you are still waiting for your favourite player to make his move while the match in reality ended 10 minutes ago
Nothing is truly live in the Universe, even a meter away from your screen, the light has a small delay followed by the perception of your brain... in a nutshell, like a sports announcer says "Play the video tape!"
At 3:36 is what keeps me up at night thinking about why constant "c" is what it is throughout the Universe, and why not some other arbitrary number. Hmmm....
Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10−11 metres to radio waves measured in metres.
Well fyi in actual practice you don't see anything hundreds of millions of light years away when you look out into the night sky, you would need a serious telescope to see any of that stuff, the stars you see are mostly pretty close. There are a few very bright ones that are thousands of light years away like eta carinae though, and you may be able to faintly see the andromeda galaxy but that's as far as you can see without serious help.
We also all see differently. We use context and standards to normalize what we see as a mass. I have no clue the way you see me from your eyes and never could.
I'm always amazed at the animation they create to co with the contents, besides the amazing contents ofcourse!
So light is like.. Noises that we hear with our eyes..
Lol I guess so?
Well.. What else would it be? If light, radiation, radio-waves and sound are all basically just variations of the same concept, then.. Is there actually a difference between sight and sound other than the way we perceive it?
Rakinjo2 in a way i guess
Faze Legend

Rakinjo2 i "GUESS" so XD
Fun fact: photons do not experience time. For them, the very same instance they are created, they are also destroyed, whether it seems to us to take microseconds or millions of years.
+Jan Sten Adámek So, photons are not matter, because they are created and destroyed? Also, how are photons destroyed? By being absorbed into a black substance?
***** Matter can be created and destroyed as well, energy is the stuff that cannot be created or destroyed. Photons are indeed destroyed by being absorbed.
+Jan Sten Adámek Vsauce?
Vsauce and Veritassium as well but mostly Wikipedia and a lot of books (Stephen Hawking is a really good author and this fact about photons I actually know from his books)
+Juan Diego E=mc^2. Energy and matter can be converted to the other, thus matter can be destroyed by becoming energy and energy can be destroyed by becoming matter.

So this photon walks into a hotel..
While at the check-in desk, the bellhop arrives beside him and asks "Can I take your bags for you, sir?" The photon replies "No, thank you. I'm traveling light."

A photon walks into a hotel.
But you can't ever be quite certain of that since its wave function never falls to zero even outside the hotel.
Sorry, that was a stupid joke, but I couldn't resist.

This channel is so underrated. It should have minimum 40 million plus subscribers. I got this video recommended by youtube after 5 years. It hurts to see youtube broken.
0:27 "Photons can't be split, only 'created or destroyed'". Doesn't that conflict with conservation of energy? (1/2 laws of thermodynamics).

What's funny is when you think about light, you always think that the light is moving at the speed of light (c). But in reality, from the photon's perspective, you are the one moving, and the photon is just standing still in space and time.

What did he mean when he said that the photon's wave-particle duality is a lie?
+HeavyRayne I think he was referring to the images and depictions of it.
+HeavyRayne
Possibly he means that both waves and particles are lies - both exhibit wave-particle duality, so they are both the same thing. Picking out photons as examples of w-p duality is therefore unfair, because everything could be example.
+HeavyRayne I have the same feeling. They exposed it incorrectly and most probably they meant what @ProfessorEGadd is hinting at. Anyways, any fundamental particle does exhibit wave-like particle duality it's just that when we look at one the other collapses and we get the famous experiment for the double slit.
Here's a better depiction actuality which corrects the script: upload.wikimedia.org/wikipedia/commons/transcoded/e/e4/Wave-particle_duality.ogv/Wave-particle_duality.ogv.480p.webm
+HeavyRayne - This is consistent with Anase's comment above, but I think the lie is that light is neither particle nor wave nor both - each mathematical model (that of particles and that of waves) can say something about how light behaves, but neither can tell the whole story. It's a lie that makes quantum mechanics more accessible?
Alexandru Gheorghe
To reiterate - all particles, fundamental or not can exhibit wave-like properties under the right circumstances. The largest things that have been observed to do so are quite sizable molecules, but in theory even people or planets could do so too.
I also think you are confusing wave-functions and wave-like properties. The wave-function of a particle describes it's behaviour, which may (or may not) be wave-like. It's wave-function collapses when we observe it because it goes from potentially doing anything to doing exactly one thing.
One cannot speak of wave-particle duality 'collapsing'. What you mean is that sometimes it is easier to explain phenomenon AS IF the particle was either particle or a wave, but not both. In fact there is no such thing as 'wave-like behaviour' or 'particle-like behaviour', because they are the same thing. They are nothing more than useful, historical constructs with a number of convenient, familiar analogues. Sometimes, such as in electron microscopy, it is necessary to consider both the wave and particle nature of a particle simultaneously.

I think light behaves as the wave-particle duality, because it travels outside of our observable time frame.
Due to physical limitations, observers can only observe things that have already happened. By the time they detect something, it has already happened in the past.
Light, on the other hand, moves so fast that it's always at the present moment as things happen in the linear time and physical space.
Basically, light will always move slightly faster than a physical observation, so it seems to exist all over the place as a wave of probabilities until it has finally been observed, at which point the light has already become a part of the past(time frame we can observe) as a particle, or an information of a fixed position of light that has been observed in this particular space-time.
Looking at it that way, light perhaps exists at the borderline between matter with mass and non-matter.
C, the speed of light, would most likely be the maximum frame rate of the material universe, because it exists right on the speed limit. Anything slower than light would produce mass(a fixed position in space-time which is perhaps what creates gravity), and anything faster would probably leave our linear time frame and become unobservable by direct physical means.
Meaning light would appear as a wave of probabilities the moment before we detect it due to light being outside of our fixed space-time, and it would appear as a particle after we do observe it and it becomes a part of the past. But it only appears as wave-particle from our linear time perspective for both cases.
It is quite possible that light exists as some other state above the C barrier, but we're only able to see it as light in the physical universe, the same way 2D beings would only be able to see flat shapes when looking at 3D beings.
If you think about it...the universe created eyes to finally see itself
And now imagine why it created penises and vaginas...
The light near me is understanding light.
“Light is a particle and a wave, however this is a lie.” What’s this mean?
Because it is not exactly a particle and not exactly a wave. No one has ever observed a single photon. Knowledge about light is only derived from measurements, theories and axioms. Although we have come very far in understanding, some behaviour of light still baffles researchers.
One could say that a photon is a photon is a photon - because we do not have a real watertight definition for it such as 'this is matter' or 'this is a wave'.
Everyone saying they got a single closing definition for what photons are is either playing God or being a bit too sure about themselves. :)

O.M.G
duality of light comes from youngs double slit experiment which showed that light propagates as a wave but becomes a particle when OBSERVED. this is a lie, because you do not observe LIGHT, you observe a simulation of light.....incandescence. also 'speed' of 'light' is an illusion. light does not move. an example: newtons cradle.....if you extended the balls all the way to the other side of the milky way and dropped the first ball, its energy would be transfered to the last ball on the far side of the galaxy, not at the "speed of light" but INSTANTANEOUS~LY. modern psyence is BS & these facts have been known since ancient times
@Siniestro Triggered. God is real, and i'm going to kill it.
"The smallest quantity of energy that can be transported" is pretty misleading. It implies an universal quantization of energy, which isn't really an accepted notion. Frequency and wavelength are, as far as we know, continuous quantities. This means you could in principle have a photon with an arbitrarily small energy, or two photons with an arbitrarily small energy difference.
+1ucasvb I believe that the quantisation of energy is well accepted in the scientific community. And frequency and wavelength are still accepted, well-established concept. I suppose that's where the whole particle-wave duality arises from?
Quantization of energy arises in several contexts and different systems, but there is no accepted notion of "smallest amount of energy possible in the Universe".
Oh, OK.
+Sum Vigil Energy quantization arises from boundary conditions in quantum systems. Unbound systems have a continuous spectrum of energy. An unbound electron, for instance, can have an arbitrary amount of kinetic energy if you simply change to an appropriate frame of reference.
Second, a photon can have arbitrarily small energy as far as mainstream theory goes. A photon could conceivably have a wavelength the size of the visible Universe and beyond.
Some upcoming theories do propose further quantizations of energy, time, space, etc., but that's not generally accepted to be true right now.
+1ucasvb I think is misleading because some photons carry more energy than others. it even says it on the video!!!
But anyway. the idea of a quantum universe it the most likely because there are alot of phenomenon that could not be explained without it. At the same time you could say that all scientific videos are misleading, because they are all theories.
So my point is that is ok to say something that is not "true" if it is the most likely, because is better to have an explanation to something than having nothing.
Title: What is light?
Kurzgesagt: Light is the connection between us and the universe.
Ok video ended byeeeeeeeeeeeeeeeeeeeeeeeeee
😂😂😂😂
That fact about visible spectrum evolving based on liquid water absorption is fascinating - hadn't heard that before!
Water filtered out/consumed the energy from the UV and x-rays hitting the Earth's atmosphere. The highest frequency/wavelength in the ocean was the visible light spectrum of the EM wave. If it wasn't for water draining energy from the EM wave, would we still have developed eyes to see in the UV and X-Ray frequencies?
@@stewiesaidthat only if there was any evolutionary advantage.
WHAT IS LIGHT !!!
BABY DON'T HURT ME
DON'T HURT ME
NO MORE
Lincoln Osiris what
@@frederickang7058 it's quite an old song exept its love instead of light XD
I have opened the video only to leave this comment
baby dont blind me... no more. sorry bud you had your chance.
The same song came to my mind while reading the videos´ title
"In a nutshell, light is..."
ROLL CREDITS!
@Francisco Nieves WTF does that even mean?
@Francisco Nieves godzilla had stroke while trying to read *THAT* and fucking died
Worry not curious repliers who didnt get the joke, the joke is basically yhat light is so fast that the video ended just as it began.
You credit so many amazing designs to random evolution
Suggestions for improvement:
I suggest green be shown in the visible light spectrum
I suggest if you use a cent as a reference you say ‘US cent’ if that’s what it is. However as an Australian I have no idea how big that is, so why not choose something more international?
It would be worth mentioning that the retina has the ability to absorb photons - that is how we see.
I’d like to see something on the properties of light but that could be a separate video 😀
Pur retina also reflects light, this is how others can see it
Light actually doesn't travel the speed of the universe, bc it would then outpace the speed of the universe, which isn't possible. Light is slower than the expansion of the universe, which encompasses everything we know, at least for the moment.
the wave model of light: im a joke to you
kurzgazat: yes
I just automatically believe what this narrator says his voice sounds like he knows everything
This has actually been a question that I've pondered, and never really got a definitive answer on.
Now I see why. I think my brain seeped out through my ears X_X
