Also mistaken for fulgurite by the more naturalistically minded, apparently. Maybe most common in the Nordics, based on viking references?

Kurzgesagt did this video where they crammed all of Earth’s history in an hour. Basically you look at a barren wasteland for most of the time until life finally goes macroscopic and then all of humanity happens in less than a second
I sat through the whole thing and it’s still incomprehensible
It’s gotten so fast that we now see significant changes in our lifetimes - cultural, technology, climate. For most of human history, it took many generations for any real change to occur.
Japan might be the record holder for fastest significant change, though. Feudalism to a modern industrial economy in a few decades.
Please. The USSR industrialization speed run is unsurpassed. Peasants to the first artificial satellite in 40 years. Also, parts of Russia are still completely undeveloped today!
Japan did it twice. They closed their borders between bouts of rapid modernizations.
