Perfection of Wisdom literature, among which the Heart Sutra is one of the shortest.

there's actually at least one other science fiction book from the 50s written by alice mary norton who used to 00:07:07 write under andre norton pseudonym who talked about a relatively similar concept in the time traders although the idea here was a little bit different here the author explained that pretty much all the signs of modern civilization are going to be completely 00:07:20 erased by the time the next glacial period begins in other words everything you see around you all the cities all the technology every major building every major structure we've ever built will basically be gone there will be no 00:07:33 signs of it left and within just a few million years there will be no one to tell the story and that's of course not really far from the truth as a matter of fact that's exactly what the scientists in this hypothesis propose and explain as well and that's of course why it 00:07:46 makes it so difficult to either prove or disprove this we currently have no idea if any of this is correct here i actually wanted to show you this beautiful illustration by one of the authors we basically have no idea if back in the 00:07:58 day when the dinosaurs were around they also had some kind of a super intelligent species that would drive their own versions of cars have their own versions of smartphones and eventually result in their own demise over time all of this would be gone to 00:08:11 history because of the way that geology works on our planet but in this paper the scientists decided to actually work out any potential ideas or experiments we can conduct on the planet to try to find out if this actually existed and if 00:08:25 it was possible in the past
