Ancient Earth Globe
- hooo 6y agoGood seeing Ian's work here! http://www.ianww.com/ http://www.ianww.com/
- pvg 6y agoA Show HN with comments by the author: https://news.ycombinator.com/item?id=17286770 https://news.ycombinator.com/item?id=17286770
- Hammershaft 6y agoVery impressive, what is a good resource for an interested layman to learn more about earth science and deep time?
- ajaalto 6y agoJohn McPhee: Annals of the former world, Simon Winchester: The Map that Changed the World, Lutgens et al.: Essentials of Geology
- arethuza 6y agoI can strongly recommend Earth: An Intimate History by Richard Fortey. Also Land of Mountain and Flood: The Geology and Landforms of Scotland - mind you that is obviously just about Scotland but it is a gorgeous and fascinating book!
- mkl 6y agoThat whole site is pretty neat. So many dinosaurs!
- tvalentius 6y agoOne of my favourite earth's 3D visualisation
- lhousa 6y agoThings escalated pretty quickly between first flowers and fist primates
- Rajdeep100 6y agoCool
- Rajdeep100 6y agopretty awesome
- martythemaniak 6y agoSuper cool stuff. If the author has time, it would be even possible to derive the major climate zones at that time using large scale features like latitude, mountains, etc. Here's a nice reconstruction of what Pangea looked like (200m years ago) https://youtu.be/VKq0pr4rbRs https://youtu.be/VKq0pr4rbRs
- tekcyb-org 6y agoI don't understand how land masses the size of africa detaches. The map shows africa attached to the US, but this doesn't make sense. I can understand water levels changing, exposing new areas that might have been underwater, drying up and turning into land masses, as well as areas that were previously land, becoming filled with water.
- danielbln 6y agoAll continents rest on tectonic plates, which kind of rest on the liquid core and are moving around on it. Let enough time pass, and the plates will move around, and the continents with them. Check out this image of the plates: https://en.wikipedia.org/wiki/Plate_tectonics#/media/File:Plates_tect2_en.svg https://en.wikipedia.org/wiki/Plate_tectonics#/media/File:Pl...
- Waterluvian 6y agoIt’s a fantastic question this stuff isn’t intuitive. http://mapdesign.icaci.org/wp-content/uploads/2012/04/atlantic_lg.jpg http://mapdesign.icaci.org/wp-content/uploads/2012/04/atlant... Consider this model: the Earth is like a puzzle. Its crust is made up of a bunch of pieces that all fit together. But those pieces aren’t unchanging. They all sit on top of a huge soft sludgey core called the mantle. And they want to slowly (slooooooowly) slide around. At each boundary between pieces one of three things can happen: - they slide against each other - they diverge from each other - they press into each other, often one going under the other, sometimes one pushing the other. A continent can move, oh so slowly, over millions of years through a combination of shifting along with other plates, or having one side of its plate grow (move away and have the new gap filled with the molten plasticy goo underneath), while the other side pushes away a plate or disappears underneath the other plate. The map I linked shows a massive stretch mark of the Earth in the Atlantic Ocean. This is one striking piece of evidence that the above effects have been happening over a long long time. It’s basically the boundary between a few plates. And it shows all this brand new ocean floor that came flowing up from under the crust (then cooled and got hard) when a gap was created because they separated apart.

- instakill 6y agoHow can you make it stop spinning?
- UncombedCoconut 6y agoDisplay Options, [ ] Rotate globe
- jacobush 6y agoSome serious interplanetary engineering, likely involving Fusion Candles on Jupiter to gather materials and fuel. Then a constant bombardment of Earth from the right angle should stop the spinning, eventually.
- myself248 6y agoI wonder if it could be done with nothing more than "solar sails" at ground level, aimed so they reflect the sunrise and push back against rotation, but exert no directional force the rest of the day.
- zcdziura 6y agoSort of off-topic: I love looking at images of how the Earth's continents have shifted and moved over time. They provide a lot of inspiration for me when making homemade maps for my D&D games. Whatever nature has done makes for much more compelling and believable maps than what I can make on my own! My latest map is based on a rotated view of what Pangaea Proxima will (probably) look like in a few million years. Looks pretty neat and provides a lot of inspiration.
- johnchristopher 6y agoAren't generators really good now ? I was under the impression they really did improve over the last years.
- fauigerzigerk 6y agoAmazing! I wish it didn't end in the present.
- dmos62 6y agoGrass appeared 35 million years ago? At the same time as the first primates? And flowers 120 million years ago? After dinosaurs appeared (220 million years ago)? My mind is blown. What did landscapes look like?
- deleted 6y ago[deleted]
- rosstex 6y agoAccording to science television, lots of palm trees.
- glial 6y agoLots of ferns maybe?
- billiam 6y agoWhat's really amazing is to think that it was only after grasses started taking over that very large land mammals could evolve on the vast marshy plains of North America and over 5 million years or so as sea levels rose due climate change become whales and other cetaceans. I wonder if humans will do the same, albeit in much less nutritious oceans that we are busily acidifying.
- simonh 6y agoWe don’t need to evolve much in the way of new adaptations anymore, we have technology. That’s how come we can colonise environments from the frozen tundra, to tropical jungles, to the harshest deserts, and now even the vacuum of space.
- nurettin 6y agoHumans didn't need much technology to live in deserts and tundras. But what if they run out of earth metals to cycle? What if they can't build sustainable energy sources? Our top modern "tech" lasts a couple of hundreds of years before totally collapsing. Humans will eventually go back to simpler tools, be it 10 million years or 100. I give it a couple of hundred thousand.
- zamadatix 6y agoI could instantly recognize the map as work of Christopher R. Scotese. Has there been other work to create paleo maps or was this work from 2000 and prior so definitive nobody has felt the need?

- jagger27 6y agoBrilliant to see where some land masses stay relatively intact and how little they've changed. Newfoundland and Labrador in today's Eastern Canada stand out to me. I really want to those weathered ancient mountains some day.
- tremon 6y agoWhat amazed me most is the relative short (recent) period in which the Himalayas formed. India split from Madagascar relavively recently, the speed with which it collided with asia must have been huge.
- Aardwolf 6y agoThis is so awesome, I just wish it could go back even further to 1 billion, 2 billion, ... years ago! If we know enough about the Earth's history and tectonics to depict it...
- theandrewbailey 6y agoI'm surprised that it doesn't go forward any. East Africa is on the move, and the Caribbean and Mediterranean Seas are getting walled off.
- dirtyid 6y agoI wish there was a way to overlay all major cities.
