Mariana Trench, James Cameron, Cuvier discussed on The Skeptics' Guide to the Universe
That I challenge my panelist got to just tell me which one is the fake. We have a theme this week. Right. Is the deep ocean. How much do you guys know about the deep ocean? It depends. It depends how deep we're going. There's a distinct boundary in it. There's nothing to be done. Well, it is the Mariana trench, so right there we're having problems. Yeah. Yeah, the essence silent forgot. Yes. All right, well let's see. Here they are. Item number one, only four people have visited the challenger deep the deepest location on earth at 10,928 meters, and about 1100 atmospheres of pressure, including filmmaker James Cameron. Number two, we have mapped only 20% of the ocean floor compared to 100% of the surface of Mars. And I number three, cuvier's beaked whales, the deepest diving whales have been spotted in the Mariana trench at depths over 6000 meters. All right, Evan, you're chatty tonight. Let's have you go first. I asked for it. I asked for it. All right, four people that have visited the challenger deep. Deepest location on earth. Including filmmaker James Cameron. I think that's right. And I seem to recall something about James Cameron heading down head and way down there. You know, what with his fascination with Titanic and that whole thing. So I think that's right. I'll jump to the third one maybe. The beaked whales are a cuvier. Cuvier's beaked whales. Been spotted in the Mariana trench. The other isn't it? So they asked the silent. At depths over 6000 meters. 6000. That's the way he wrote it. I am reading, it might not reading, what? You are already wrote it wrong. I say it wrong, Steve wrote it wrong. Sorry, sorry. All right, the M trench. At the apps over 6000 meters. Why wouldn't that be? It's a terror what I'm seeing here is that both are acceptable to their area on a trench or Marianas trench. It says sometimes called marianus. So maybe we could do a deeper dive into that to see why there was that discrepancy, but a lot of the references I'm seeing say that both are acceptable. Maybe it's one of those foreign pronunciation things or americanization things. But there it is. Really? You can say, but all I know is that every ocean person that I'm Friends with is like all super pedantic, whenever people put an S on it, they get all bitchy about it. Bring them on the table to talk to her. I mean that they're correct. True. True. Very quick anecdote. That's early on in the show. In one of the segments, I refer to hieroglyphics, hieroglyphics. And somebody wrote in and said, I'm an expert in egyptology and it's hieroglyphic writing. There is no such thing as hieroglyphics. So I thought that was an excellent example of pedantry because it's not like everyone doesn't know exactly what I'm referring to. But I'm like, fine, if the experts all say hieroglyphic writing, that's fine. And he actually said, I've never heard any expert in the field ever say hieroglyphic writing. Every say hieroglyphics. It's always hieroglyphic writing. Then like a month later, two months later, the same guy emailed me back and said, I'm going to have to retract my previous day, but I apologize. I was at a meeting and all of the egyptologist experts were saying hieroglyphics. Good follow up. Because they heard our show. Clearly. He was a scientist. Well, right, where was I? I jumped to three. I skipped two. So the question, yeah, so the only question here is 6000 meters. That's pretty deep. Can they handle that pressure? Is that where they are? They've been spotted down there. They don't necessarily, you know, habitate that, you know, live down there. They may be just gone deeper and then come back up to a more feasible living depth. But the one about the 20% of the ocean floor compared to a 100% of the service of Mars. I think a 100% of the service in Mars is correct. I think the problem maybe with this one is 20% of the ocean floor. We only 20% of the ocean floor. Maybe the ocean floor is bigger than I'm giving it credit for. So it's either the whales or the ocean floor or I have to choose one shoot. Only 20% of the ocean floor that doesn't seem so low, but shoot. Steve, I'm gonna say, I'll say the one about mapping 20% of the ocean floor is the fiction. Okay, Jay. All right, so the first one about only four people going down 10,928 meters. I think that one's correct. I mean, you know, I remember reading stuff about James Cameron and the Titanic and, you know, he loved the Titanic, then he makes the movie. You know, Steve I didn't like that movie. Everybody in the world except me like that movie. I didn't like it. I just thought it was a movie Titanic. Yeah, they basically like, yeah, this event happened and it is completely manufactured like this total fiction around it and I thought it was silly, but that's but that's not why he went on the challenger. I know that. I'm saying that. Oh, yeah. It was for asphalt. Okay. I didn't like the movie. Gotcha. Okay. But I admit that the world loved it and I didn't. All right, so we have mapped only 20% of the ocean. I thought we mapped more of that, but I mean, for science or fiction, I guess we're on there. I don't know. I mean, this is tough at this point. So much could have changed, just in the last 5 years, but I do remember hearing some type of low percentage that I was surprised to hear. But you know, it's hard to get down there. So I get it. It's this last one that's been bothering me. Evan, did you pick this one? I forget. Well, I almost did. All right, I'll just say it. I just don't see a mammal going down to the bottom of the trench. I just don't think a mammal can go down that far. So I'm just gonna say this one is a fiction and Cara. Well, okay, so cuvier's beaked whale. It says here that it has been spotted in the Mariana trench, but only a depth of 6000 meters, which is really deep, but not as deep as challenger deep, which is the biggest gouge in the Mariana trench. And that's almost 11,000 meters. I mean, that's bananas. That's like a really specialized, what's it called? Diving pod. Oh my God, what's it called? Submarine. Separate. No. No. Here you got it. It's got to go in the book. Damn it. It couldn't have been. And I know that James Cameron has been down there. I think it's more than four people, though. So there's two of these seem like fiction to me. The cuvier has beaked whales which sounds the most bananas I think is science. But two of them seem like fiction. So I want to grapple with some details here. So only four people having visited challenger deep seems like too few. I think it's been more than that, because there have been several trips on that, what is that, that deep sea whatever? Actually, my ex-boyfriend was on that trip. They gave them all rolexes. Is that crazy? What? Like on that big camera trip, but he didn't go down in the dive pod. So I don't know. I'm trying to commercial. Actually, would have been in this submersible, yeah. But then the other one that's bothering me is that we've mapped only 20% of the ocean floor. We've got the whole day motion floor. We know what the ocean floor looks like. I don't think we have like amazing resolution, but we've definitely mapped the whole thing. Okay, that's the one that really bugs me then. I'm gonna say that that's wrong. I think we've mapped the whole ocean floor. All right, you all agree with the first one so we'll start there. Only four people have visited the challenger deep the deepest location on earth at 10,928 meters and about 1100 atmospheres of pressure, including filmmaker James Cameron. You all think this one is science and this one is science. Yep, this one's correct. So there had been three trips total, three trips, the first one had two people in it. The second one was James Cameron. So just alone to one person that's the third person. And when at the time that James Cameron went to the bottom of the challenger deep that bought.
