Thank you so much for setting me straight. And, I admit to not having recourse to so much source materials relative to the Tarzan dailies. My own experience are more held with the seventies version comic book by Joe KUBERT. Once again, I appreciate your kind clarification.
Please forgive my lateness to the party. At times whatever logic is being used by an author can inhibit the flow of a story if said author is being too concerned with a real sense of authenticity of any science involved. Though too much reliance of the handwavium of any unobtanium employed also can leave a lot to be desired. A balance of sorts is best preferred to maintain a fluency of readership understanding and not just personal focus.
Please pardon me being late to the party here. I find that when any sort of logic especially that called science, is too much a focus any story tends to suffer from flow being nearly nonexistent. Yet too much of any sort of handwavium or even unobtanium(insert current buzzword)also detracts from any sense of reality, too. A balance of sorts is best preferred.
2003 REVAMPED “BATTLESTAR GALACTICA” anyone?!
