| Beautiful and scary at the same time. Almost like the iceberg was a planet on its own with mountains, valleys, crevices. Then everything goes haywire. The fall of a majestic titan. The destruction of a world. |

| ▲ | baubino a day ago | parent | next [-] | | There’s also something very organic about it. I had to keep reminding myself that it’s “just ice” and not a living being. | | |
| ▲ | dotancohen a day ago | parent | next [-] | | Especially the spine. If you had shown me a portion of the video with that thing moving as such, I would have believed it to be some leviathan. Which brings us to the video itself - horrible. Presumably the original sound was recorded, because we hear it under the music. Just let us hear the sound! The people watching this video are people who appreciate nature, not people who need a dramatic soundtrack to be entertained. And what is with changing the speed of the video every 60 seconds? Either show it at real speed, or speed it up, but not both intermittently! At first I thought there was an issue with the video playback hanging. I would absolutely love to watch the original, unedited source. | | | |

| Massive appreciation for whoever adjusted the position of the camera at 7:23 (3:18 in video) |

| I would have thought it would generate enormous wave, but that's clearly not the case. I think some of the biggest waves was generated by a mountain sliding or collapsing in the sea. I expected something similar here. Anyone know why not? |
| |
| ▲ | GuB-42 a day ago | parent | next [-] | | It is not a very energetic event for its size. The iceberg is floating, it can't accumulate a lot of potential energy before flipping, so when it happens, there is not enough to make big waves. The center of gravity of the iceberg barely moves. A mountain sliding into the sea is different, these higher up rocks have a lot of potential energy, that convert into kinetic energy as they fall, which is transferred to the water as they splash down, making big waves. | | | |
| ▲ | cucumber3732842 a day ago | parent | prev | next [-] | | The amount of water actually being displaced isn't changing much, it's just kind of rearranging around where is water and where is ice. | |
| ▲ | javier2 a day ago | parent | prev | next [-] | | i suppose its not actually displacing a lot of water volume, unlike a landslide. | |
| ▲ | staplers a day ago | parent | prev | next [-] | | All its mass is already on the water so it's not displacing anything. It probably made some splashes but it seems like a fairly round object rotating rather than smashing into anything | |
| ▲ | dist-epoch a day ago | parent | prev [-] | | Maybe because ice floats, and it's almost the same density as water? |

| Surprised the bottom of the iceberg crumbled so easily (like sand) at 4m 16s: https://www.youtube.com/watch?v=UufMqwyO7pY&t=4m16s I'd have assumed it would be colder and more compacted (being toward the bottom and further under water), and therefore harder. |

| ▲ | brianpan 8 hours ago | parent | next [-] | | There are different ways to create an iceberg. You are probably thinking of a hard chunk of ice breaking off into the ocean, but probably a more common way is glaciers running into the ocean. A glacier is basically a "river" of snow and ice slowly flowing down a mountain. It would generally not be very compacted. Fun fact: smaller chunks (less than 15m) are called "bergy bits". | |
| ▲ | amszmidt a day ago | parent | prev | next [-] | | How cold is cold? :-) Water below ”sea” level tends to stay around -1C (salt water) to 4C. Below that, water becomes ice… Ambient temperature can drop to -40C … internally these ice blocks hoover around -10C. | |
| ▲ | FromHoiPolloi a day ago | parent | prev [-] | | My take would be that underwater temps cannot get below freezing. So the surrounding temperatures above water can be lower than under water. | | |
| ▲ | Pooge a day ago | parent | next [-] | | > My take would be that underwater temps cannot get below freezing Yep, density of water changes with temperature—it's the only thing that has that phenomenon—and therefore the colder water is always at the surface. That's actually what made life possible since life could survive despite a frozen surface. Happy to be proven wrong, but that's what I learnt making cocktails and investigating clear ice :) | | |
| ▲ | dotancohen a day ago | parent [-] | | Lots of things change density when temperature changes. Water is unique that below 4°C, it gets less dense as it cools - and that trend continues even through the phase change. That's why, as you mention, ice floats, and the surface freezes first, and fish can live below a frozen surface. | | |
| ▲ | Pooge a day ago | parent [-] | | > it gets less dense as it cools Right!! Thanks for correcting me. |

| ▲ | mrloopex a day ago | parent | prev [-] | | Freezing point of water changes with salinity and impurities. By definition a liquid cannot be below its freezing point until it has completed its phase change. | | |
| ▲ | RetroTechie a day ago | parent | next [-] | | > By definition a liquid cannot be below its freezing point until it has completed its phase change. Supercooled water is a thing: (and I've seen it a few times myself) https://en.wikipedia.org/wiki/Supercooling | | |
| ▲ | wahern a day ago | parent | next [-] | | Superheating, too, and that's something that can happen in a microwave, occasionally causing severe burns when superheated water flash boils. AFAIU, it's the same phenomenon--lack of nucleation sites to kick-off the phase transition. | |
| ▲ | mrloopex a day ago | parent | prev [-] | | Does that mean every TTT diagram is wrong? Nevermind I just learned about CCT diagrams. I guess having only one year of materials engineering means I should STFU. :) |
| |
| ▲ | FromHoiPolloi a day ago | parent | prev [-] | | Yes. My point was that it's easier(?) to get below freezing point above water than below. So while the cold air keeps the upper part of the iceberg (relatively) intact - it will slowly melt below the sea until the center of gravity changes enough to flip over. |

| Not saying its fake, just that what I see surprises me: ice is only slightly lighter than fresh or sea water, so vaguely only 10% of ice mass is above surface level; when it "flips" multiple times, it just seems like 50% of the ice is above water as if the other supporting 80% helping it float that high are totally missing... |

| Crazy how the most liked comment under the video as of now discusses AI video generation |
| |
| ▲ | saalweachter a day ago | parent | next [-] | | The music also gets talked about quite a bit. My immediate reaction to a "what is with this loud music, I can barely hear the actual audio" comment on YouTube was to assume the channel was afraid of being copystruck by the iceberg's lawyers. | |
| ▲ | maxlin a day ago | parent | prev [-] | | Especially as physics-oriented and long videos are exactly the kinds that are easiest to figure if they're AI. Artificial Intelligence isn't the issue. Natural Stupidity is. |

| A fun game to draw your own iceberg: https://joshdata.me/iceberger.html First seen https://news.ycombinator.com/item?id=26201160 |

| It stops first? Maybe the bottom hit the seafloor? |
| |
| ▲ | dotancohen a day ago | parent | next [-] | | That's what I thought too. The sudden stop is actually two phenomenon compounded. One, the mountain of ice contacts bottom. Two, the video speed changes from ~8x to 1x. | |
| ▲ | readthenotes1 a day ago | parent | prev [-] | | One of the comments said just that. "Grounded near disko bay" iirc. Another comment said that icebergs melt blow water faster than in the air and that flipping is a fairly common thing to do because the center of gravity changes. | | |
| ▲ | maxbond a day ago | parent [-] | | You can see bathtub rings on the underside as it's lifted up. The rings are caused by it's melting faster under the water than in the air, so there's a discontinuity at the waterline. |

| Divest from any kind of S&P500 or cool tech stocks. Invest in renewable energy projects. The US government is failing you, only money talks. |
| |
| ▲ | inigyou 19 hours ago | parent | next [-] | | Money and utility are often uncorrelated. Many solar panel companies went out of business in the last few years because solar panels are so cheap. | |
| ▲ | therealdrag0 12 hours ago | parent | prev [-] | | I think culture and politics is more important than divestment. | | |
| ▲ | mrpopo 12 hours ago | parent [-] | | How do you think you will change culture or politics? In the US, money IS the culture. Politics go where the money goes. | | |
| ▲ | therealdrag0 11 hours ago | parent [-] | | It’s very hard. But a more direct lever than divestment. Utilities operate in very regulated environments. Changing regulation is the lever that matters. Money can buy influence such as media and access to influence culture and politics. There’s a number of non-profits that work on this angle you could support. LCV, CCL, CATF etc. |

| Can more experienced people describe how to verify this video as non-AI generated? Is there a scientific source in Greenland or Denmark that tracks such incidents? Or could satellite passes before vs after confirm what happened? |

| Honestly, my first thought watching this video is "I want a root beer float." Something in the way the icefalls as the iceberg is flipping over just makes me think of that... |

| Gotta say, I haven't seen anything this jawdropping in a long while. |
|
| ▲ | catlikesshrimp a day ago | parent | prev | next [-] |
| I would have described flipping it over before collapsing. The title seems a clickbait, but is no quite that.
Keep in mind that most of the iceberg is off camera, as shown during the first minutes. It lost 80% or 90% of its total mass but most of it isn't seen until the end, when the iceberg goes back to the right. |

| I was expecting more waves. I am wondering if this video was AI generated. I hate that it is so hard to trust your eyes nowadays… Edit: Did a quick background check, video seems legit. |
