Show HN: Plot modern addresses on Earth 240M years ago

Hi HN, I built this by adapting GPlates (<a href="https:&#x2F;&#x2F;www.gplates.org" rel="nofollow">https:&#x2F;&#x2F;www.gplates.org</a>), an academic project providing desktop software for geologists to investigate plate tectonic data. I&#x27;m amazed that geologists collected enough data to actually plot my home 750M years ago, so I thought you all would enjoy it too.<p>Even though plate tectonic models return precise results, you should consider the plots approximate (obviously we will never be able to prove correctness). In my tests I found that model results can vary significantly. I chose this particular model because it is widely cited and covers the greatest length of time.<p>The visualization itself is open source, though I have not yet cleaned up and pushed the plate tectonics integration (working on that right now): <a href="https:&#x2F;&#x2F;github.com&#x2F;typpo&#x2F;ancient-earth" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;typpo&#x2F;ancient-earth</a>

I felt so silly trying to zoom in and see satellite images of my house as it was 240M years ago.

I would love to see what a potential future Earth would look like, and where I currently stand will be<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uLahVJNnoZ4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uLahVJNnoZ4</a> is pretty cool

As a child I was fascinated by the idea that the cliffs of Moher (<a href="https:&#x2F;&#x2F;www.cliffsofmoher.ie&#x2F;about-the-cliffs&#x2F;geology&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cliffsofmoher.ie&#x2F;about-the-cliffs&#x2F;geology&#x2F;</a>) stood at the mouth of a massive ancient river but I&#x27;ve never found a picture of the earth in the geological past which showed such a river.<p>Nor does this model. Anyone know enough about geology to explain why? Is it because rivers are not represented at all?

Cool! But the model of earth appears to experience gimbal lock - use quaternions for rotations.

So the land that I stand on today, India, was once part of Africa and America&#x27;s landmass. Crazy!

I love that you can rotate the globe around and there is a position where you can only see water.<p><a href="https:&#x2F;&#x2F;www.dropbox.com&#x2F;s&#x2F;a0s75tyqtoh0hrd&#x2F;Screenshot%202018-06-11%2013.41.43.png?dl=0" rel="nofollow">https:&#x2F;&#x2F;www.dropbox.com&#x2F;s&#x2F;a0s75tyqtoh0hrd&#x2F;Screenshot%202018-...</a>

One thing: At 540 My ago, you misspell &quot;Cambrian Explosion&quot; as &quot;Cabrian Explosion&quot;

Can we extrapolate this into the future?<p>Update: found this video: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uLahVJNnoZ4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=uLahVJNnoZ4</a>

Wow! This gave me a whole new perspective on the Uruguayan coast, it&#x27;s so cool to know that what I am seeing latched off the Antarctic peninsula!!! Specially since it so recognisable. Just a nice piece of trivia, but awesome for me.

Is there data telling how deep the oceans and tall the mountains were during those eras?

Fascinating! I tried to see how the Alps form but it&#x27;s quite a complex process

The difference between 260M and 240M in the Western US is really big. My hometown, Flagstaff, Arizona, goes from being near the ocean to being hundreds of miles away from the ocean, like it is now.

Some explanation of what&#x27;s going on in NA: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Laurentia" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Laurentia</a>

Great. Suggestion-<p>1. Can you add the number of years ago (eg. 100,000, 1M, 20M, 200M) next to the periods in the dropdown for those not familiar with it.<p>2. Can you simulate the changes automatically so it evolves?

The Americas look like the &#x27;old world&#x27; in this model, to my surprise, except Mexico looks new. Asia could use better lighting on the marble.

Nice work! I feel like it can provide some perspective about things like nationalism, etc. Like a minor version of the &#x27;overview effect&#x27;.

Very hard to steer on a cell phone (Android, Brave browser) - pinch zoom kept flying me into the Cosmos.<p>Like the idea though - will try later from desktop.

Do you plan to extend it to show the future?

It&#x27;s really great to play with the million years selector and the up&#x2F;down arrow.

Really like it! Especially the short explanation of the age is quite educating

This is awesome, nice job!

Does that mean that an ocean that big could produce super hurricanes?

Be good to be able to turn off current country outlines

why show modern borders for 240M old earth?
