How Does Light Actually Work?

[@explorationnewreaches]

An interesting aspect of the photon is that it behaves both as a particle and a wave. It's a video packed with a lot of knowledge!

[@CTRLyurself]

Music in the background is a tad loud but a good video

[@Soysaucy328]

Photons do not experience time. Everything is instantaneous for them. How would they be able to change/decay if they don’t experience time?

[@spindoctor6385]

Photons don't "experience" anything. The notion of experiencing things doesn't apply to non conscious objects.

[@gregpieczka8996]

We observe photons from our perspective of space time. For us photons got certain speed for photons it's an instant journey. Instant because there is no distance between them. I'm guessing Universe imploded not exploded. We accelerating inward!!! We just seeing like it's expanding. We'll one sunny day we will learn more. We just not ready for the whole truth yet. Good day!

[@Michael-v3h1u]

Idk... I gotta assume if we know how fast it moves then we've evidently clocked it some kind of how and therefore if we can clock how long it takes it to reach a point it must have some sort of substance... unless its not being watched.... maybe? Lol!

[@tommygrandefors9691]

Massless particles in rest do not equal duality alone as it seem to be described in this video. All fundamental elements (including electrons, positrons, quarks, which actually have a rest mass) show the same duality properties since they are also individual waves in their own field but ”turn up” as particles due to excitation (disturbancies) in the field. For some strange reason all force carrying particles such as photons (electromagnetic force), gluons (strong nuclear force), gravitons (gravity, if they exist) seem to give a shit about the Higgs field. 😊

[@paulkita]

Photons do not interact with the higgs field and therefore have no mass

[@paulmakinson1965]

Don't photons get redshifted into oblivion as they travel through expanding space-time? There is a point when light is so redshifted that it's wavelength becomes equal to the visible universe. Can space-time just be just another quantum field? Could it be that the non-locality of entanglement just be a non- interaction with the space-time quantum field? I studied quantum physics before Quantum Field Theory and Quantum Chromodynamics existed (yes, I'm old and I have forgotten most of the mathematics), so I'm sorry if my questions are silly.

[@greg-op2jh]

No you are correct..I guess their point is technically with sensitive enough equipment they would still be able to detect them.

[@jerrybecker1628]

Your depth of knowledge belies your age!

[@klowen7778]

Yep, currently Redshift is key to measuring interstellar distances, but the possibility of photon degradation would lend support to the the 'tired light' hypothesis.

[@oddtodd1522]

Please forgive my ignorance but... I understood red shift as being relative to the point of the observer, not inherent to the photon. Red shift seems to be used as a measure of direction and distance rather then an indication of the energy remaining to the photon. So the photon doesn't degrade so much as our ability to measure it at a distance does?

[@fuffoon]

This narrator has a good voice, an interesting but easy accent, an even yet expressive inflection, and perfect pacing. Good job.

[@Mac2point1]

[@Wootguy238]

I can not listen to this video because I do not enjoy the voice.

[@Tim-Temple]

I was never interested in science per se, but the more I learn about science and nature, the closer I come to understanding this reality and it's creator. Light has no mass, yet we need it to detect the properties of mass objects billions of light year's away. I believe the photon's unique properties are no accident but a crucial part in helping man understand our place in this universe. This is the real mystery (and miracle) of the photon.

[@Billydevito]

THE MUSIC IS TOO LOUD !!

[@susanlynch6680]

Great content, but for me the music was too much.

[@overcamehim]

The more i learn about the nature of time and the nature of light, the more i am persuaded that they are manifestations of the same phenomenon. In other words, light is the manifestation of time and time is the manifestation of light. You may ask, if they are the same why is time invisible and light is visible? Consider this simple thought. Because the photon is a particle, light is visible because time is a wave it is invisible. Sadly im not a mathematician.

[@matt112fly]

doesnt make sense

[@highwayred480]

Energy is the carrier of light😊

[@tomnoyb8301]

Science/Physics strives to understand the world, most often by providing equations. Usually the simplest object equations are derived and more complex systems are either calculated, measured or inferred, but the simplest equation is fundamental. For example, the simplest and most fundamental hydrogen atom's discrete electron 'shells' may be derived in closed-form from the Schrödinger-equation and the atom's boundary-conditions. From Hydrogen's equation's the whole Periodic table is explained. Arguably, the whole field of Chemistry is explained. However, when it comes to the single-photon, Physics shows tragically little curiosity about its equation. Before bloviating on-and-on, *What is the equation of a single-photon?*

[@joeblog2672]

Great video!

[@SpaceSeekers-6789]

so much interesting knowledge, the universe is infinite to us

[@apollo-r5z]

Light is the oscillation of the darkness of virtual photons and electrodynamic quantum fields, no one can see light, because it is the vibrations of darkness.

[@wess-cp7vd]

Always interesting how little humans understand.

[@RomoRooster]

From the perspective of a photon, they travel instantly across the universe and experience the entire evolution of the universe instantly. For them there is no billions of years of travel time, every point in space and time is connected.

[@schism6976]

I figured you just flipped the light switch?

[@akossule6680]

Can you explain WHAT IS ENERGY

[@waynesaban2607]

It’s what you get after drinking a lot of coffee

[@johnshepherd6925]

Energy is mass. E=mc² Sorry, I know it's a smart ass answer. I couldn't help myself. 😅

[@christopherm3271]

The ability to do work (move mass) or transfer heat

[@alexlang2086]

There is something weird about saying A photon could be a particle cause it just duplicate itself insanely fast all around as it travel from its emissions point.

[@lewebusl]

Photons are decaying into longer wavelenghts during their lifelime. Redshift is not caused by the space streaching, it is the natural decay of an oscillating fields , the photon. But the photon decays so slow relative to a human lifetime and we only can detect the decay after millions or billions of years into the lifetime of the photon.

[@Richard-darixdax]

Does a photon experience acceleration? I mean from formation. Is it possible that all mass is C and light is still?

[@johnshepherd6925]

No, they don't. Photons only travel at the speed of light from their very creation.

[@c_lo01]

Light is observable, dark is not to the naked eye. Thats why we cant figure anything out cause we only look at light. "For every action there is an opposite and equal reaction." Without dark there can be no light.

[@alfonsosamaniego738]

Dream music ok. Great music video.

[@cthawk6770]

What force exists to move these photons?

[@deathbyraybies]

it seems to me that everybody here have forgotten that the photon is theoretical has never been proven to exist people like to put a lot of faith into a belief

That’s where faith belongs!

How does light work? Just raise your hands, because many hands, make light work 😂

[@byker4lyfe1]

Don't know if you have already done one on this but can y'all do one on how gravity works in space? I mean I know how gravity works on earth, we stick to the earth cuz of the mass of the earth but I wondered before about how gravity works in space 🤔

[@johnshepherd6925]

There are plenty of videos on this topic. I would try to explain it, but it would take a lot of words, and I may not do it complete justice. I will say, gravity has no limit to its distance. If there were two stars on opposite sides of the universe, they would eventually make their way to each other, drawn to each other's mass. It may take more time than we could imagine, but they would still make their way to each other.

[@byker4lyfe1]

How do solar sails work if photons have zero mass?

[@cthawk6770]

Are photons electromagnetic?

[@RobertFrench-t9j]

Because of the volume of the MUSIC, I can’t understand what the narrator is saying. I have to remove my hearing aids and turn on captioning. Then I miss the graphics while trying to read. Too bad. Seems like a good channel, but it’s just too much of a hassle trying to watch. Why do content creators think loud music is necessary for their videos? It isn’t. It just drives away people with impaired hearing.

[@Billydevito]

If only there was an app that could reduce music and enhance voice. I’d pay 0.99c for THAT !!

The very 1st thing that God created was Light However it could also include the total initializations of the entire electromagnetic spectrum, Also consider it from a super brilliant programmer point of view where all the variables, constants, arrays etc that are in a master programs are initiated and the system boots up. God is the master creator and programmer of everything and He hold everything together by the power of His word. He will wind down this universe one day and remake a new one of perfection afterwards.

Good question. If you can picture a regular average stick and think of it like an AVATAR and imagine the light that comes out of it when you burn it in a pit is really the structure or LIFE BLOOD of the object. Light is mass and so is energy. The 3 in tandem seems to make a mystical bond. Molecules form but why?
