The fact that they changed the button from M for "mini" to W for "wumbo." This is what makes this the best channel ever.

"Planck-length is the distance light travels in a Planck-time. Planck-time is the time light takes to travel a planck-length." *Makes perfect sense to me*

I love the fact that temperature literally became physics at a certain scale. That’s a fantastic way to explain what heat and temperature really are

It's so impressive how you manage to sum up incredibly complex concepts in the span of a 10 seconds that took me a full semester to study

The suit being set to Mini for going smaller, and Wumbo for going bigger is amazing.

I'm 40 years old now. Watching your videos does something for me that I didn't expect would be possible anymore: I watch and experience the childhood wonder we all used to have with new experiences. I just press play, sit back, and take it all in. Thank you so much.

0:41 “Please slip into this magic science suit so you don’t die and can still see” This made me EXPLODE with laughter

This channel might be one of the best things that has ever happened on the internet. The quality of animation, narration, writing, music... It's far beyond what any other educational channel has ever achieved, and it somehow keeps getting better with time. I have nothing but massive respect for whoever is running this spectacle.

I think it would have been worth mentioning just how small the Planck length actually is. Our adventurers pressed their shrink button a total of only four times to get down to the size of an atomic nucleus. But they would have to press it SEVEN *MORE* TIMES in order to reach the Planck length! And even then, the Planck length would appear to be the length of a marble.

The idea of a bee flying faster than a jet but for only like a few seconds before it craters the ground is hilariously awesome.

Makes me think about what Ant-Man (2015) could’ve been. I imagine a segment or segments in the movie where it’s just exploring the microscopic/subatomic world in an Interstellar-like style with beautiful visuals and everything like in this video. Like the subatomic scene but longer. Would’ve been cool imo.

I just find the narration so funny after the 9 minute point. From him just being confused with the planck length to scolding bird for going smaller, its just so good!

Let's see if I got this straight. So the reason why bumblebees "shouldn't be able to fly" is because someone forgot to factor in the increased density of air at their size?

"In the end, the perfect place might be where you are right now; not too big, not too small." That's why I love this channel, it delivers knowledge that can fill you with nihilistic despair one moment, and then drop some really heartfelt inspiration the next.

I honestly love watching this series with my bird. It makes me so happy.

Thank goodness for you guys. You're the only channel that makes something like particle physics accessible to everyone. This is no small thing in a world chocka with "information" that is difficult for many people to make sense of and contextualize. I have a lot of respect for the fact that you rely on your own resources to make money to support the channel. I wish you continued success going into the future and look forward to watching many more outstanding creations. Bravo!

"if you look up the universe seems large and strange, but if you look down the universe seems even larger and stranger" is probably the best way to describe the universe.

I’ve always struggled to imagine what the world would look like at the size of a bacterium. Imagine what a line of ants would look like at the size of a bacteria. Amazing vid as always!!

These videos are crazy!! So much knowledge and responds one question gives 100 more questions to wonder. I wish there were a way to know it all.

Hard to believe I've been watching this channel for almost a decade. It's been a very existential but enjoyable ride.

It's mind bogglingly amazing that even with such a limited time this channel provides us the absolute best content out there..

your videos never fail to impress, they're super easy to understand ,fun and interesting .Never stop making your amazing content

1:45 basically every time I try and run in a dream

You can really feel how much this channel has improved since their first animation. This looked so beautiful :)

I think many people don't give credit how insane this video is. Highly informative, yet easy to understand with incredible animation. Love this channel.

I LOVE playing around with scales. This video was an absolute joy to watch!!

I like coming back to videos such as this after a while, when I have learned a little bit more about the topic in school. Watching them again just give me a sense of how amazing these videos really are, simplified just enough to not overload you, and detailed enough to spark your interests.

It absolutely amazes me how far this organization has gone since 2013. Astonishing video. I cant even imagine how much work it was to create this on a scientific basis and I am totally certain that people that dont know this channel, will definitely think this is sci-fi. Thanks many times to all of you guys for all of your work! Exactly as you mentioned, you are igniting curiosity and will to become a better human being. I am sure that you are probably well aware of this, but you are creating a better future for all of us! :)

My god I can’t believe how nobody is mentioning how beautifully the video was ended off at 10:12. I also give huge props to whoever composed the soundtrack, it really makes these words hit home. “If you look up, the universe is large and strange. So incredibly large and strange. But if you look down, into the tiny and and extremely tiny, the universe seems even larger, and even stranger. In the end, the perfect place might be where you are right now - not too big, not too small” Whoever writes the script for Kurzgesagt, I truly appreciate how you end off videos each time. Really leaves me thinking about it and more so appreciating life in of itself. Thank you everyone in the Kurzgesagt team!!!

This is the most comprehensive depiction of the micro-universe within our own, I have ever seen. Thank you!

this channel's videos just keep getting better and better. I love it

This channel somehow never fails to make me feel both incredibly small yet also large

I love these kind of videos

Thank you for enlightening me to what short people see in this video, ❤ the art.

"If you look up, the universe is large and strange, so incredibly large and strange. But if you look down in to the tiny and extremely tiny, the universe seems even larger and even stranger. In the end, the perfect place might be where you are right now. Not too big, not too small." This hits me. Might be my favorite quote of Kurzgesagt.

We just adopted an 8 week old kitten and I've the last few days wondering what the world must look like from his size. He's so tiny everything must seem massive to him. This was a fun way to think about scale and how a walk across the room feels like nothing to me, but could feel like walking a city block to him.

I've always known Kurzgesagt videos are absolute jams but this video is especially well-done! Nice job, you completely blew my mind.

Thanks for sharing this amazing video! Both of these realms are amazing and huge.

This channel is really pushing the boundaries of what an educational video could be.

I’m a molecular biologist and you PERFECTLY captured the micro realm. Kind of how I see it in my head when doing my science :)

It was amazing to watch the microscopic universe, so much that was learned😲

David, you're a poet. I have never seen a physicist describe the universe so eloquently and poetically as you do. Thank you for these videos. Keep them coming.

Love how this channel can remind me that our “normal” isn’t so normal at all and that everything we experience is incredible, miraculous even!

This feels like an honorary addition to the "size of life" series that is some of this channel's best work. Love it!

Thank you so much for everything you do, and every mind you have touched. I really appreciate the Feynman reference.

This channel right here. This got me back into this stuff.

It's astonishing how such a small space ends up being the size of our solar system at the molecular level. Maybe we're at the microscopic level of a much larger world, but it's beyond our comprehension because of our relative size. I've always had this thought from time to time.

The pure, child-like fascination this channel inspires is absolutely mind numbing. Well done as always everyone. Your efforts are greatly appreciated.

For those who haven't done quantum mechanics at university level, I'd like to share a realization I had while doing Schrodinger equations on one dimensional particles. The field of influence is not where the electron may be but is actually the state of electrons when not directly interacting with an 'observing' photon. It is hard to really explain but imagine one location where you find the electron in the bubble-shaped region. This is what is called an eigenstate and there is one for every location the electron could possibly be. An eigenstate is essentially a measurable state of literally anything and imagine all possible eigenstates for an object to be everywhere and everything that particular item can do in its existence in the universe. An example set of two eigenstates is that of a fridge door, it can either be open or closed, we therefore can say there are two eigenstates of the fridge at any time those being [door open] and [door closed]. Now imagine I blindfolded you and asked you "what eigenstate is this fridge door in?" and remember there is no peeking or feeling if cold air is there. The only answer you can give is that the door is either open or it is closed, this is what we can call a superposition. As far as you are concerned, the fridge could either be open or closed which leaves you with the only correct answer is that the door is both closed and open until I let you take that blindfold off to check. This is not only an interesting thought experiment but it also actually describes the way particles exist in our universe at any given time without interacting with another particle. In other words, when no one is watching, that door is both open and closed simultaneously until something 'measures' it. I say measures in quotations because how we observe things is by measuring them, we can't tell you where in that nebulous cloud the electron is until we send something to interact with it like a photon of light to check to see which eigenstate it happens to be in at that particular moment in time. What is almost impossible to comprehend is that these electrons actually do exist in the state of superposition when nothing is interacting with them. The electron, and all quantum particles for that matter, exists in a state of being in every possible eigenstate in existence until another particle interacts with it and collapses the waveform (the big cloud is a 3D waveform) giving that interacting a particle a glimpse of where the target particle is at that particular moment. The reason every big thing we deal with doesn't dissolve into cloudy soup is because there are quadrillions of other particles to continually trap each other into far more confined forms basically all the time. A solid table or floor is made up of billions of nuclei (which are confined quarks trading gluons with each other) with electrons bound by the constant exchange of photons (the electromagnetic force carrier particle) and they are often constantly bombarded by radiation from the universe including neutrinos and buckets of different photons. And before you think "doesn't that mean I can break the speed of light because the electron could be here or on the moon?" The one stipulation about the universe that remains true is that no, you can't break the speed of light. What happens to a measured particle like an electron after it is measured and returns to the cloudy superposition is that the cloudy superposition can only expand at the speed of light (or in electron's cases, very slightly below the speed of light because it does have a little bit of mass which slows it down a very small amount). Just a reminder though if you don't get it by this point and think you are stupid, I reached this realization while actually doing the math to calculate how particles actually do this (yes in one dimension but multivariable calculus exists) at a university level with calculus to VASTLY simplify the geometry [you could do it by just geometry but it would take you a lifetime to do one calculation calculus can do in 2-5minutes]. Don't feel bad because you didn't take an advanced course, just take it yourself if that is what you want to do

when kurzgesagt narrator says "what are you doing, stop it" in an english accent he reminds me of my dad when he gets angry and it sparks something in me

I got so much joy from the human setting the dial from mini to WUMBO!

You, everyone on the team, have created a whole other world yourself with this video. It feels... strange, bizarre even to see the real world through these ethereal animations. This excitement I get, this supernatural feeling of wonder is far far too rare in life, only achievable through escaping into fantasy stories usually. We are all truly blessed to have you!

Shout-out to the camera man for providing us with those epic clips 🤙

The Planck length segment gave me some Stanley Parable vibes, I love the humor you guys involve in this (also, love the M for micro on the belt being turned upside down to be W for wumbo)

the animation team really deserves a raise , and the way this channel provides information , i really share this video to children and students so they realize and most importantly imagine the literal scales of what they are learning

Saying the size og humans being «not too big, not too small» is too perfect.

Now this is fascinating 👏. I've been waiting for such videos🙏🙏 thank you guys

Watching Kurzgesagt's videos always reminds me of why I fell in love with science all over again. Thank you for always making such masterpieces and spaking curiosity all around the world. Things truly would not be the same without it.

I'm a space/time/blackhole enthusiast and all this time my brain was busy wrapping itself around how big the universe is. When there is a completely polar opposite in size world at our feet and fingertips. My existential crisis just went over ten fold after watching this video!!!! Absolutely brilliant, looking forward to your next video!🥳

This first shrink is literally just Grounded, and I love it.

Fantastic work! These kinds of videos demonstrate how awe- inspiring and breathtaking the universe really is. Sometimes I think the coolest jobs in the world are held by scientists.

I felt like a little kid watching this video. This feeling of awe and admiration towards the natural world is something that everyone should get to experience at least once in their lifetimes. Thank you for this video.

9:28 “You know what the problem is? You got it set to M for Mini when it should be set to W for Wumbo.” Excellent job as always, Kurzgesagt.

9:30 Er hat den Knopf einfach auf Wambo gestellt 😭😭😭 So gut ❤❤❤

Now I want a TV series that the characters go in adventures in those places!

I just need to say, once again, Steve Taylor, you voice is perfect for these videos. It inspires curiosity, caution and a sense of hope and adventure. Thank you, and thank you to the whole Kurzgesagt team, writers, researchers, animators, all of you. Your content is easy to follow and fun for everyone to watch. :)

Kurzgesagt videos seem to specialise in giving existential crisis vibes while keeping you interesting. Great videos and hats off to the team!

The fantastic narration aside, the background music combined with it made this video so engaging. And I remember in another video on how Kurzgesagt makes their videos that their music and sound effects are all original so that maybe the reason why this video hooked me in.

Your Channel is Godsend ! ❤ thank u so much ❤❤

I am just 11 years old but still I love your videos..

That was beautiful. There were moments were I got genuinely terrified and claustrophobic, but there were also moments were I just absorbed how amazing the world is. Thank you Kurzgesagt!

Wow, this just goes to show how much effort the Kurzgesagt team puts into their videos. I learned large amounts of information about things on the opposite extreme. The research, the animation, the soundtrack! Amazing job guys! Thanks for the gift, I really enjoyed it!

The work done in these videos is insane. ❤

this is my favorite video on 2022. every new video is getting better by the year.

It's my very favorite calendar!! -John

When the video ended, i felt like I myself had gone to the trip. Love the animations, visual, voice EVERYTHING The videos are getting more cinematic and interesting over time. THERE'S NO BETTER CHANNEL THAN THIS

This topic is what i am thinking deeply and thanks for answering

this was oddly poetic. thank u for making this❤

I love that they flipped the M for mini to W for Wambo to return back to normal size 😂

I dont know why but im bingewatching your videos and this is the 14th one

This videos make me tear up having so much explained so well nothing is better then these videos keep up the amazing work

Love the "picnic in the park" homage to the original "Powers of Ten" movie, which pioneered this type of "zoom in/zoom out" look at our world.

the first two levels are fascinating..I would love to see a video of series of humans exploring those worlds at that scale.. It looks amazing!

Wow thanks for the epic adventure !!

I just started watching these again, and they feel better than ever.

I'v almost finished my bionanotechnologies studies and it's Just amazing to see condensed in a single YT video years of daydreams becoming arts. I really want to thank you kurzgesagt for everything you do, no one ever takes me seriously when I fantasize about the "hidden worlds", thanks to all of you I Always feel "less alone" in this world ❤️ Grazie.

the visuals are amazing!!

literally made my day!!!

Channels like this are carrying the torch of all the old tv shows and books I was obsessed with as a kid in the 80's. Hopefully current generations of kids become curious about the bigger (and smaller) picture of our existence as humans and they seek out videos such as these

I'm studying science in college, and every time things seem to be too much and I get overwhelmed, I go back to your videos and it never fails to renew this spark for science I had years ago. Thank you.

I noticed that, in most episodes, the monkey in the intro is doing something different - like in this one, it's looking at some blades of grass, and I've seen it looking at a phone, a glass of milk, and a lot of other stuff (usually related to the video). I just wanted to say that this is an awesome detail, and it really highlights how much effort you put into your videos!

This was fun. It put together the concepts about what I know into a cohesive experience.

I'll never shut up about how much effort and research they put in their videos. the consistency is just truly astounding, so proud of everyone involved :)

Love watching the bee get cuter. Something about this artstyle made the giant be absolutely adorable. I love bees.

There is not much to say about this other than how amazing this is. So fascinating that it leaves be speecheless covered in goosebumps. I think im gonna binge watch this channel for a while. Great work. How fascinating science can be? Knowing our knowledge about everything is enormous but still mysteriously incomplete. There is much more to unlock in this world. This video is worth the time 💙💙

How have I been sleeping on this channel for so long?! IT'S AMAZING

Yes!!!! Your calendar has become a birthday tradition of mine. I have them all.

One of my favourite videos on UKposts

Wow, this is actually a really good video. It gives great, easy to understand comparisons of what it would look like if yiu were shrunk down smaller abd smaller. Prolly my fav video. Reminds me of ant man quantumverse but with some actual science behind it. The plank length realm is insane! You know, we like to scale up and try to imagine how big things can be but we dont often imagine things scaled down. Its pretty fascinating.
