I'm done with all those big channels, they just keep saying the same thing,it takes infinite energy...The wavelength thing is now I know why it is so. Saw another guys awesome video of general relativity in 3D spacetime and it had only 10k views..Man you guys deserve to have millions more

I have been watching physics videos on KZfaq for as long as I can remember but no one has ever bothered to explain these stuff wuite like you. You literally ask why to the most generally accepted notions in Physics realising that most ppl actually don't even understand the concepts. This is now my favourite Physics channel. Thank you. Keep up the good work

*puts on double pocket protector* Theoretically, you could travel to the speed of light if you were able to get rid of higgs Boson particles out of the atoms. You wouldn't have mass therefore nothing to slow you down. Don't ask me how to remove it that isn't my job. My job was simply to cause chaos.

I imagine quantum fields as kind of LCD screens. On those, lighting up tiny red, green and blue points can conjure any visible object. Quantum fields do that in 3D. Seems intuitive to me.

as my professor said before he started his semester class.."Physic is about WHY not WHAT"..keeping asking why,the physic will start explain it to you..i sub to ur channel for how easy to understand it and the topic really bring back memories from my Uni years..

BW : Unfortunately, I'm going to change how you see the universe. Me : Jokes on you, I'm into that shit.

Whenever I keep asking why my teachers at some point can’t explain because they’re bad. This video is literally everything I asked for. That formula I don’t even need to remember in order to write because right now i know how waves and mass work

This has become my new favourite channel. Awesome visualizations. Looking forward for a complete series on quantum physics and relativity. Keep up the good work.

Suddenly, this 79 y/old starts to understand the inter-relationship and inter-dependance of things (I think!)

The weird part is, YOU can go as fast as you want. If you put in twice the energy, you can get to any speed as long as you measure from your frame of reference. If you want to get from point a to point b and the two points are a lightyear apart, there is no limit for how fast you can get there. This is due to the time dilation from moving this fast, if you want to go faster, you can. But from an outsiders perspective you are just getting closer to the speed of light and thus they see you slowing down in time.

~7:30 You are making huuuge mistake. "If you traveled at the speed of light particles in your body couldn't communicate, because they also abide the same speed limit". The problem in the R in SRT (special relativity theory). In the frame of reference of the object moving at the speed of light, all of it's internal processes remain consistent with it being at rest, thus from your own perspective you body would retain it's original shape and properties regardless of the speed you are traveling at (speed according to which reference frame?). In other words, as you approach the speed of light, you'd see the entire universe collapse along the axis of travel, but nothing noticeable would happen to you. You could go and make tea, look out the window, read a book and look out the window again, and except the universe looking quite differently to what we are used to on earth everything would seem completely normal. btw, ONLY if you stopped would you notice, that multiple lifetimes of the universe have passed while you were making tea :P

Your videos put such a different but intuitive spin to understanding concepts I've learned about many times in the past. Great work.

I love finding videos that explain these complicated physics and concepts in terms I can understand.

Never seen it explained quite like this, thank you

I’m 43. When I was about 9 I read in a simple book the simple answer: that the faster things go the more massive they become.. so that you need more and more energy to accelerate the object…. eventually they get to infinite mass and you need infinite energy to accelerate it.

I'm blown away by your content. You might be my new favorite channel

Thanks to the algorithm I’ve been on a marathon of your videos, super informative and underrated !!

Your animations are so fun and intuitive, I love it

This was an amazing explanation. Most people know about the whole infinite energy thing etc but the way u explained about why infinite energy is required made it really good.

Fantastic explanation, illustration and production, will definitely be back for more

Finally someone who truly addresses the WHY properly! So appreciated!

Like some other people have written, I’ve watched LOTS of videos on physics subjects like this…. BUT, this is the FIRST one in a decade or more where it’s been taken beyond high school physics AND explained in a brilliant way that makes this understandable without making excuses about only REALLY being able to get the idea of you can think in mathematical equations. Love the graphics and the script is even better. Thank you. Please make more…. Like… what’s an electron volt, and what can you find out by smashing high velocity protons together?

This is the best explanation of this phenomenon I have ever seen on KZfaq, not even the great physics channels have explained it in this level of detail! You certainly got my subscription!

Man...you get right to the point in every vídeo. Amazing! You deserve much...much more subscribers!! Well done!

I watch science videos endlessly for years but I have learned new things here. Brovo!

Nothing can exceed the speed of light. That only applies to matter moving through space, but, according to general relativity, space itself has no boundaries to its upper limit and can do whatever it wants.

best description of wave particle duality i've ever seen!

Oh my gosh I finally got it! Finally!!! Thanks! Keep up the good work!

Also... 7:15 - The speed of light is One Planck Length divided by One Planck Time. So if spacetime were thought of as being granular, the speed of light is simply taking One Quantized Step.

I'm an electronics engineer i have seen awesome engineers and professors..but sir you are it...a true master ...I salute 👏 you

Thank you for your thorough and lucid explanation of complex matters, I always enjoy listening to your lectures. Only one comment if may, I think it would be more effective to do away with the music in the background. It's a bit too loud and somewhat distracting. Thank you for all the good that you do, best of luck to you.

Finally. I've been looking at videos which provide an explanation of why the speed of light can't be exceeded. This one made it clear to me. Thank you.

Fantastic content. Thank you and keep it coming.

I think you can jump from the moon to the earth, you just need to train so hard your hair falls out.

That was explained beautifully. Thanks. Subbed.

07:00 I think it is not correct, photon speed within an atom at near speed of light still travel at speed of light between an electron and proton

I like to think that we can travel at the speed of light. Or rather, we already are. We just aren't traveling through space very fast. But we are traveling through time very, very fast. Our perception of time arises from all the subatomic interactions occurring within our nervous systems. Every particle interaction in your body is a tiny little clock ticking away and driving the narrative of your timeline and conciseness. And those interactions occur very, very fast. Of course, we only experience the total sum of those interactions and are completely oblivious to them. So while we are moving slowly through space and very quickly through time, photons are moving only through space. They don't move through time at all. We find it fascinating that light can move so fast. But if light could be conscious, it would probably be fascinated by us and our strange ability to move through both time and space.

For all the times I've heard both the good old Newtonian laws and some variation of the "you need infinite energy to reach light speed" now I realize I've never actually asked the simple question "But why?". Great video.

2:58 it all fun and games till someone gets pissed off

Outstanding video and narration.

I can't say enough how great your gift is. Wow.

Another excellent video. You deserve millions of subscribers. I'm glad to be one of your early ones. I'm looking forward to watching your channel explode ...like you were jumping to the Moon.

Well done sir. Well done. 👏👏👏👏

I learned something today. Thank you.

That visual at 1:33 just changed my whole conception of reality wow

Thank you for a great video. Just one note: dividing by zero is NOT infinity, it's undefined and impossible. If 1/0 = ∞, then ∞ x 0 = 1 causing all sorts of nonsensical results and basically breaking maths. So 1/0 is undefined.

Wonderful explanation

A great simple explanation!

As an amateur dabbling in physics, I've thought that lightspeed means the limit of _everything,_ given its wavelenght is the Planck lenght, or the smallest unit of timespace there can be. In order to be anything, that anything would have to give up being everything in that moment, and enter the arrow of time (aka follow causality). While it might not be the smallest unit/distance _possible,_ for all frames of reference in our current reality _it is._ A photon is not traveling anywhere, _it is everywhere that is crossing the path of the photon._ For its frame of reference, not a single second has passed from the Milky Way to Andromeda, but from ours it's been a mind-boggling 5 million years for a round travel. Anything (conceptually) faster would simply fail to be registered by our instruments as they fall outside our realm of causality, which is what I believe the realm of dark energy, an energy that is invisible to us by all means except on its effects of expanding timespace faster than its own speed. So chances are good the photon is not the limit per se, but it is for anything that can be observed. Hyperlight travel would forcibly need to bend timespace itself as it would be impossible to reach the finish line without ever moving from the start line. Tl;Dr: God needs to upgrade the ram on his Micro Center built computer he made while drunk.

On the basis of this vid I've subscribed. Good work. Flaxen Saxon.

Nice presentation! new sub.

You, Sir, are, officially, my, new, favourite, YT, channel!! Yes, I’m in a bit of a coma...

This channel is gonna explode.... I'm happy I found this

Nice videos buddy... Keep going👌👍

While watching your videos (which I really like btw) I was wondering which software you use to create your 3D animations. Since the screenshot you used in this video is from Blender 2.8 I suspect you use Blender. So my question: Do you actually use Blender or did you just plug in that screenshot randomly? (I use Blender myself so I was quite intrigued about your animations and was constantly thinking: How would I achieve this effect?).

2:55 I laughed for 5 minutes straight when the red guy punched the blue dude... and it cut off before he made contact which multiplied the hilarity

"The Imagination Trap" by Colin Kapp. Excellent story illustrating infinite mass + infinite velocity.

Your content is excellent!

Light speed "c" and why it is that speed, was determined by Maxwell c=1/SQR(Mu x Eo) where Mu is the permeability of free space and Eo is the permittivity of free space both of which are easy to measure.

Great videos! Love the channel. Do you use Blender for all your animations?

holy how are you so good at explaining

you just gained a sub good work though I knew it beforehand i liked how you beak it into simple pieces that a common man can fit together

This is the first time I have seen the concept of wave/particle duality and the quantum fields explained and illustrated to a point that I get it. It's amazing to think we are all just made up of these. Vibrations in a field

Impressive visuals!

In the future we'll probably be able to buy infinite energy at the local 7/11.

Great channel. Im on board.

The deBroglie equation describes the problem mathematically but doesn't explain it physically. The simplest explanation is that (a) the vacuum is responsible for both macroscopic motion and the quantum time-evolution of matter, and (b) the vacuum's capacity or activity level is a constant. So time slows down inside moving objects because their motion uses up some of the vacuum's processing power. At the speed of light, the vacuum is maxxed out by the object's motion, so the object doesn't evolve internally at all, i.e. time slows down all the way to a complete halt. And it's impossible for matter to go faster than the speed of light, for the same reason that it's impossible for sound waves to go faster than the speed of sound: the speed limit is based on the medium's capacity to support the wave phenomenon.

Great video. I learned a lot. The concept of a particle/wave's wavelength approaching 0 is great and very intuitive. That said, there is a lot of requisite knowledge needed to follow along with this video. Perhaps a video(s) going over the knowledge dependencies would be good?

My inquiring mind thanks you!

You sir, have just earned a subscriber

Speed of light travel and beyond is possible via "Lense-Thirring" Effect or "Frame dragging". (look this up). If an object gets close to the speed of light, it gets really massive, that gained mass (through gen relativity) and speed will drag space-time around it. The object may appear or even traverse space at the speed of light but because it's "dragging" the local space, it's relative speed against its local space would still be below the speed of light (and the energy demand is still *not* infinite). Eventually, it would even permit faster than light travel. It's likely the same mechanism how some galaxies might be flying through space very close or even beyond the speed of light.

Yes I will definitely retain all this information

Thank you!

The sad part is, even if the speed of light was attainable, the universe is so big we still wouldn't be able to see even 1% of it.

Someday I will mention you in my speech in Switzerland

Good video and explanation 👍👍 With all this talk of quantum communication via entanglement going around, though, I've been wondering. Could "quantum speed" be "faster than light"? The information online is very mixed when it comes to this, and I'm trying to find out if there's truth to it, if its being considered at least in theory, or if the public/media is once again just misinterpreting scientific matters?

The speed of light is attainable, light has been doing it for billions of years.

This channel is so underrated

One day we'll acheive not only light speed but beyond that limit.

Definitely Not me watching a mind boggling and fascinating video yet laughing and totally getting distracted by the Orange figure getting ready to knock out his “playfully” pushing friend at 3:00 😂😅

I agree with everything except the last part. Light always travels the same speed regardless of what speed you're traveling, because of time dilation. When you get to light speed, time freezes. So essentially nothing will happen anymore.

From what you say and visualized about matter moving through higgs field this comes to mind that there is some sort of friction with higgs field that resists change in momentum. But what if we increase speed gradually? Also when you say you can't jump to the moon since the force of such a jump will rip you apart, again what if we apply this force slowly to reduce the resistance of inertia as much as possible?

Or , another scenario. Two objects travelling in oposite directions at 1/2 of speed of light. It doesn't require infinite energy to achive that.

I began with some of the black hole videos and now I'm here. For reference, I had Astrophysics, Quantum (Field) Theory lectures and a part of my work is related to Particle Physics, however I went more into Materials Physics. Your display of stuff seems unmatched to me. Not a single textbook or lecture delivers the knowledge of these topics that easy. I had the hard way going by foot like so many others. I'm really enjoying your explanations/lectures :) ... sometimes I asked this particular question. "But why?". To my professors. After I saw I started to embarras them I stopped that. Now I'm on the other side of the table and I'm really happy if one or another of the students is asking questions about how stuff works and we can discuss more deeply. But sadly, it seems to be increasingly rare as the time goes forward ...

The answer to why the speed of light is around 300000km/s and not anything else is also simple in itself - light speed is defined by electric and magnetic permeability of the considered environment, and in pure vacuum those constants make us almost 300000km/s. They're different in various gases and liquids, which reduce the speed of light in those places and that's what causes light refraction in them. Those quantities simply define how quickly the electric field can transfer vibrations in itself. Now the question is why those two quantities have such values. :P

This video should have a huge caveat that says: *based on our current mathematical observations*

One question I had when watching this. Can you call the fields "static"? And thus infer an absolute velocity from things? I know your graphics are trying to visualize the impossibly small, but from one Planck distance to another, could they be described as "static in the universe"? Or is this just my 3D mind not getting what the field is. Thank you =)

“It’s an interesting thing to think about, but also impossible and unnecessary.”

Wow,awesome

When you said that at infinity a wave length is 0 that reminds me of the man who took a school hostage and passed out his book “infinity=0”. I doubt his book would entail anything relevant to this but it is weird to think about.

Light isn't just moving, it's expanding, that's why it behaves both like a particle and a wave

At this current time and date it's not possible but in a couple of hundred years let's revisit this.

You should do a video about riding a gravity wave as a theoretical way to travel faster or as fast as light in space like with some sort of gravity field bending space its self.

"Why is the speed of light 300000 km/s?" I think isn't the best phrasing given the speed of light being a fundamental whatchamacallit. Perhaps a better wording would be "Why do we experience a second when light moves 300000 kilometers?" And then the answer would be down to how many interactions can happen between our particles mediated by an electromagnetic field that sends information at that speed. Or I could be wrong. I don't know.

When considering the vastness of space the speed of light is really, really slow.

fun fact: the speed of light defines the meter, NOT the other way round! edit: That is why the speed of light is exactly 299'792'458m/s and thus has no fraction whatsoever. And one more thing: Out of the seven base units (SI base units), time (seconds) is also one of those. The more accurate we can define (measure) a second, the more accurate a meter becomes (see above). Luckily for us, atomic clocks achieve just that!

Does anyone know where the music comes from?

This type of teaching is like watching toddlers feel around crawling in the dark opening your mind open your mind

You could have gotten into Louis de Broglie's Law of Phase Harmony: "Universal coherence" - a "mind boggling outlook." Phase harmony in de Broglie theory relates a local periodic phenomenon (the 'particle clock') to a periodic propagating field in such a way that relativistic invariance is satisfied. If a similar phenomenon in the cell is relevant it should couple the global oscillation pattern locally with periodic (mechanic, electric, biochemical ???) processes. Coherence as consciousness. "Ghost Tones" Manfred Euler is a Professor Emeritus of Physics at the University of Kiel.

Refraction is not about light traveling slower, it’s information propagating at different speeds as the phase velocity becomes different from the group velocity. Light always travels at full speed by definition.
