@reddit: Yes, according to Chrome's plan, they calculated the speed of propagation of the petrification ray for Senka so that he could calculate the time of complete petrification and then get under the revitalizing water
@AlbertoLaFlare: These aborigines are the descendants of astronauts who landed after the general petrification. Some knowledge still remained, otherwise they would have run around with batons and communicated with sounds.
@Raydan: Well, some kind of weak explanation. In fact, they run around with batons :They don't communicate with sounds, OK, this could have been passed down from generation to generation. I don't see anything but speech, even at least some wall inscriptions that could remain useful for the descendants of astronauts. And here is the concept of footage and time...
@AlbertoLaFlare: A convenient and fairly understandable concept that has been passed down from generation to generation along with language and fairy tales. Another thing is that the dimensions of these segments themselves could eventually acquire other values, since there is stupidly nothing to compare them with.
Well, let's not forget about the conventions of the world. When compared with reality, there is a lot of doubt there
@Raydan: By the way, another point is ripe for reflection here :D Well, let them know about the concepts of meters and seconds. But how did they figure out how to control this damn thing? They only showed how these stones got to the island, but they did not say how they learned to use them. It had to be guessed somehow, and even Senka didn't know what to do until he heard Oka's scream.
@AlbertoLaFlare: again a convention. And most likely the first activation was a lucky accident. The guy who picked up the device said that when it fell, it formed a sphere of such a radius and glowed for so many seconds. And then the device worked. Well, then it's not a tricky business
Did Senka pour water on himself during petrification? We'll find out in the wake. series
Well, let's not forget about the conventions of the world. When compared with reality, there is a lot of doubt there
