The Big and the Small

I have a surprise for you.

I’ll tell you about it in a minute. First, let’s have a little fun. Come with me.

I haven’t told anyone this before, but I actually live in the fun room. I just gave you a tour of my house, where I spend a large portion of my life thinking about the size of things.

I have visitors in the fun room from time to time, but after a few minutes, they’re usually pretty funned out and leave me to my crises. But one day, something unexpected happened.

It was 2013. Wait But Why was a few months old. And I got an email from someone named Philipp Dettmer. I was slightly unsettled by the pp and tt, but I decided to read what he had to say.

He explained that he lives in Germany where he makes animated educational videos about a lot of different things, kind of like Wait But Why but a different medium. I took a look at his YouTube page. It was named a random string of letters:

kurzgesagt

Apparently it means “In a Nutshell” in German, but I didn’t know that at the time and was very close to being done with Philipp Dettmer for good when I decided to watch one of the videos.

It was delightful.

I watched another. And another. And then it hit me.

Philipp—this random man in Germany—also lives in the fun room.

The next day, we were on the phone. There was a lot to talk about. We decided we had to do something together, and we settled on adapting one of my early posts into a kurzgesagt video.Kurzgesagt did an updated version of the video in 2018.

In the seven years since then, Philipp and I have become great friends, and I have not missed a kurzgesagt video since. Whenever Philipp and I get dinner, we head straight to the fun room to talk about the universe. And a few months ago, we decided to collaborate again. It was time to go public with the fun room.

At some point in our pasts, we had both become enamored with two fun room icons, Cary and Michael Huang, known on the internet as the Huang Twins. The twins do a lot of cool things, but it was their Scale of the Universe toy that we loved most.

Inspired by their work, we decided to go for it. We wanted to make the best size explorer we could imagine. We called it Universe in a Nutshell.

Of course, it took roughly 18 times longer than we thought it would. We brainstormed the interface for quite some time, and then Philipp, along with the incredible kurzgesagt team, dug into working on illustrations and animations, while I worked with the team on the written explainers.

Thousands of human hours later, the app is done. 250 objects, 30,000+ words of explanations and fun facts, just the right mood music, and what we think is a pretty great interface.

Here’s how it works:

The app is a giant wall. The wall is impossibly large—large enough to fit full-sized galaxies on it. The wall is also impossibly high-resolution—hi-res enough to contain sharp images of subatomic particles.

I know it seems weird that I’m talking about it as if it’s a real object, but I have a good reason: to get the full mind-blow effect, you have to realize what you’re looking at. You’re not moving forward and backward through a tunnel of objects—it just seems that way because your brain will refuse to accept the insanity of the actual sizes you’re seeing. By reminding yourself again and again that all of these objects are “painted” on the same 2D wall, you’ll hopefully experience some fun mind-bending moments.

The app looks like this:

And this:

And this:

And there are three ways to zoom:

You can tap any object for an explainer and fun facts. All of the facts you just read in the fun room are also in the app, along with a million other things. (The surprisingly-good-for-Wait-But-Why-illustrations from the fun room are the work of Kurzgesagt. Don’t think this is some new normal.)

Three more things:

1) The app is $3 in the US store, which, considering the fact that a magical infinite wall should really go for like $2.5 million, is a huge steal.

2) If you like the app, please give it a rating or review. For example, here’s my review:

3) This is V1 of the app. As we made the app, we had a constant side conversation going on about possibilities for V2, V3, and beyond. We’re launching today, but this is just the beginning. We want this app to be a brain playground that just keeps getting better and better. And here’s where you come in.

As you use the app, whenever you have an “I wish the app did X” or “It would be so cool if the app could do Y” thought, we want to hear it. As this is V1, we of course also want to know whenever you have a “This isn’t working right” or an “I think this fact is off” thought. In the app’s menu, you’ll see a “feedback” tab, where you can tap the feedback email address and let us know what you’re thinking.

Okay, here you go. Click the left app for iPhone/iPad, the right one for Android.

___________

Also: To commemorate the app launch, Kurzgesagt did their own fun room creation today—a delightful video about the sizes of stars.

    Love the comparisons. It’s the easiest way to open the eyes of the masses about how small that we, our world, and the whole entire past and future of everything that every human has ever known — REALLY are. (I believe that when I’m sure enough of the world IS on ‘the right page’ about these things – THAT’S when we drop the news about our slowly accelerating trip into “The Great Attractor”).

        First, we did not evolve from Monkeys Sir. That’s utter nonsense Sir. We are fearfully and wonderfully made by an awesome GOD. Who made God? He is the Alpha and Omega, a to z the first and the last the beginning and the end. INFINITY was created for a reason. and God is beyond INFINITY. so in our finite present state we cannot understand everything but there will come a day when Jesus will glorify those who trust and believe in Him and the Father. then knowledge and will be given to us. till then we have first learn the answer to the essentials and fundamental questions.

            Not only does it say all things will be made known, which makes me think we have a lot of time to go, or at least a lot of information to go,
            And in Daniel it says many will run to and fro and knowledge will increase.

          Hypothesis A: The Bible is written by humans, who we know are obsessed with the movements of human genitals.

          Hypothsis 2: The Bible is written by the Creator Of The Entire Universe, observable or not, with ultimate power over everything. It turns out he is obsessed with the movents of human genitals.

I would ask you to read the bible once from start to finish and then take sides after you understand it. don’t make up your mind by listening to others, read the source and make up your mind. what have you got to lose…if you are right, you will find better points to tell people like me that we are wrong.

            being fond of something and truth are different things sir, truth usually is hard because it asks us to destroy everything that we have understood so far. but that’s the only way. God is a good God Sir, He loves us and has made in His Image and has GRAND plans for us Sir. Far more grander than our greatest imaginations. but not everyone gets to inherit it. only those who believe Him get to inherit it. you ask Him in prayer to reveal Himself to you Sir.

      Great site. But you can only observe the things in the same diameters. Here, the author grants an analogy in which you can compare the things with different magnitudes together in a familiar environment like the United States map.

    Looks like an amazing app, though you should release the software under a freedom respecting license e.g. GPL, Apache, MIT etc. and just ask for donations to compensate you for your effort instead of charging for download.

    This would be beneficial in a few ways:

    It would increase your audience size – many people will not run software unless they have access to the source code and can view and modify it, and rightfully so (imagine buying a food product and the manufacturer refuses to disclose the ingredients);

    It would help solve device/os compatibility issues (as the source code is available to the public and those that have to will be able to make the necessary modifications);

    It can potentially increase the profitability of your project as many of those who will enjoy your software will give you much more than all the three dollars you’re currently asking;

    You mention that this is V1, and that a V2 and V3 are planned for. You’ll need developers for that. Once your source code is released you are in a position to get valuable contributions from developers who are looking to esablish a reputation by contributing to a popular project. You won’t need to seek out developers – they will come to you. Also third party development and integration will be much easier.

    Your software will be available for usage to people in the world who earn 3 dollars an hour who otherwise would certainly be hesitant to purchase your product and probably forego using it;

    Overall, the more you remove the barriers to access the more people will use your product thereby leading to greater revenue potential and greater exposure.

    the mass of the sun is also insane. If the sun were the size of a basketball, it would weigh 3.5 *10^20 tons. Thats one quarter the weight of all the oceans on earth. It was actually really hard to find something of similar scale to to this.

      I think your numbers are a bit off there. The sun’s average density is 1.41 g/cm3, meaning a basketball sized sun of the same density would only weigh around 10kg.
      You may be thinking neutron stars, but even that is wrong, as that would be on the order of around 10^16 kg

    My 6yo & 8yo have been asking about the sizes of atoms and quarks, which made me realize how much I’d forgotten HS Chem2. Thank so much for this mind-blowing discussion! May it inspire many future scientists.

    One thought: While I realize the f-bomb at the end is meant to emphasize the dramatic, here I feel it drains the eloquence from the cosmic climax.

    I’m also a big fan of kurzgesagt!

    It just occurred to me that everywhere you go, you carry the center of an observable universe with you. Everybody lives in a different observable universe. Even two intimate lovers with their faces pressed so closely together that their corneas are touching are still living in infinitesimally different observable universes. On a scale where a neutrino is the size of a US penny, the space between two touching corneas is probably on the order of light years.

    I used to follow Vsauce for a specific kind of content. Moving between topics at random, forming odd connections, exploring topics that aren’t available anywhere else, oddly wise philosophical endings and links to hidden gems like the dictionary of obscure sorrows.

    I think it ended somewhere around three years ago. Since then, two things happened. One, Michael Stevens networked, Vsauce2 and Vsauce3 happened, cross-advertising with other education channels happened. Two, Mind Field and Mind-Field-like videos happened. These are more slick, superficial explanations of famous math or physics concepts.

    I guess that the fundamental distinction is between educators and explorers. When you are an explorer, you just read fun stuff, think about it, and post it for others to see. You get on the road less traveled, you are weird and a lot of what you find goes nowhere. But in the long run, some of what you do sticks, because you are the only one to go that way. I still, after years, remember the ending of The Science of Awkwardness (link: sadly not present because Disqus formatting hates happiness). But the best explorers are drawn to the opportunities, the talking to scientists, and the responsibility that comes with that, and they become much less personal (and less personally invested) educators. Maybe I’m just a hipster at heart when it comes to knowledge, but being small and relatively unknown does have its advantages.

    The reason I post it here? One, the same thing is beginning to happen with WBW. I cannot provide meaningful feedback on the app because it is just The Scale of the Universe with sideways scrolling, added objects, and different graphics. It feels forced. Together with the book in the works I am afraid that WBW might lose its distinctiveness. I hope I’m wrong. The Post itself is novel, but also kinda buried under all else that’s happening.

    And two, this type of channels is super hard to find. I found one replacement channel by complete chance: Jacob Geller (I suggest Fear of Depths and The Horror of Universal Paperclips and Space Engine to start). Do any of you, fellow WBW readers, know any others?

    My favorite explanation will always be Douglas Adams’s Total Perspective Vortex:
    “Trin Tragula — for that was his name — was a dreamer, a thinker, a speculative philosopher or, as his wife would have it, an idiot.
    And she would nag him incessantly about the utterly inordinate amount of time he spent staring out into space, or mulling over the mechanics of safety pins, or doing spectrographic analyses of pieces of fairy cake.
    “Have some sense of proportion!” she would say, sometimes as often as thirty-eight times in a single day.
    And so he built the Total Perspective Vortex — just to show her.
    And into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she saw in one instant the whole infinity of creation and herself in relation to it.
    To Trin Tragula’s horror, the shock completely annihilated her brain; but to his satisfaction he realized that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it cannot afford to have is a sense of proportion.”

      That is interesting! Thank you for sharing.

      In retrospect it’s also a little misogynistic though, don’t you think? It’s weird to realize that so many of the great scientists and science fiction writers of the 20th century, who many of us grew up treasuring and revering for their love of this stuff, were also profoundly sexist, often in both overt and subtle ways.

      If you’d like to learn more about this topic, here’s a good post about Isaac Asimov in context: https://baseandsuperstructure.com/isaac-asimov-science-fiction-harassment/

        Out of all the possible counterarguments to the notion that this scene is misogynistic, this one is the most straightforward: Many others are subjected to the same device with the same results, presumably disregarding gender or alien race or anything past sentience. The only outlier is Zaphod and his case is definitely not a glorification of men. If you really go deconstructive on it, it just glorifies his self-obsession in this particlar situation, and even that is debatable.

          Oh, I wasn’t aware that this device came up outside of this passage. It’s been a while since I last read any Adams.

          Either way, my assertion was only in reference to the passage quoted above, which seems to present Trin’s wife in a fairly misogynistic light. Even ignoring the concluding sentence, her characterization is reminiscent of a number of sexist stereotypes (e.g. the “nagging bitch” type). I don’t think this is a controversial claim.

            I think comedy is often stereotypical. It gets away with that by being indiscriminate about the targets. Bigotry isn’t fun, but neither is a just world. In my opinion at least THHTTG strikes the balance well by taking on humans as a whole. Remember that the inventor is also quite a stereotype. The important thing here is the device and the contrast with the down-to-earth reason for its existence. But that’s already digging into it a bit needlessly.

              I’m not sure that’s true. If I make a sexist joke disparaging women and then make another disparaging men, that doesn’t “cancel out” the sexism in my earlier joke. In general I like Hitchhiker’s Guide (it’s a classic for a reason: it’s really funny, as this passage demonstrates), but we can enjoy the book while still acknowledging the parts of it that are problematic. I don’t think that’s an unreasonable standard.

              In any case, a just world sounds pretty fun to me. Perhaps we’re using different definitions of fun?

              I think we reached common ground here, except that I’m really curious about just world comedy examples, if you have any. It might be that I just haven’t yet read the right things, but I have trouble coming up with an example.

              Oh, just world comedy? I mean, the best example I can think of is comedy that is legitimately wholesome, like when a cat suddenly zooms out of the room for no reason, or when a child makes a funny-looking face. Even something like a cheesy pun/dad joke (e.g. “Is it the dog? Are you paws-itive?”) probably counts, if you’re into that sort of humor. I’m pretty sure all of those things would still exist in a just world. People laugh at all kinds of things that aren’t mean-spirited, dark, hurtful, or reflecting on the world’s injustices.
