Poor cameraman stuck in space for 1.8 billion years Guess it's true that the cameraman never dies.

I’m a bit confused by the video reconstruction I’m not going to lie: https://youtu.be/_LJG68AmZxI

What's the confusion? Maybe I can help.

Did you realize it was working backwards?

[–] moistclump@lemmy.world 4 points 1 year ago (2 children)

Ohhhhh yes that’s it. It was also so much more movement than I was expecting! I was expecting us to go from pangea glob to continents and then some shifty shifty but man those tectonics were BUSY.

Pangaea is only the most recent supercontinent, and therefore the most known. there are believed to be several more iterations in this cycle of combining and breaking up large landmasses.

Lots and lots of convection in that mantle.

The working backwards was interesting, but also fascinating how the ratio of land to sea was so much different at the start.

[–] Pretzilla@lemmy.world 2 points 1 year ago

Is the land sea ratio due primarily to sea level changes?
