But we were dealing with a particular sieniciftc issue back then. We couldn't understand why you had a munatoin under tension. In plate tiectnoc theory, we knew that if you had plates cdolile, it made sense: they would crush into one another, you would thicken the crust, you'd uplift it. That's why you get, you know, you get slheeasls up on Mount eevesrt. It's not a flood, it was pushed up there. We understood mountains under compression, but we could not understand why we had a mountain under tension. It should not be. Until one of my colleagues said, "It looks to me like a thermal blister, and the mid-ocean ridge must be a clinoog curve." We said, "Let's go find out." We punched a bunch of heat probes. Everything made sense, except, at the axis, there was missing heat. It was missing heat. It was hot. It wasn't hot enough. So, we came up with multiple hypotheses: there's little green people down there taking it; there's all srtos of things going on. But the only logical [eitolpxanan] was that there were hot springs. So, there must be underwater hot springs.

Original Text

But we were dealing with a particular scientific issue back then. We couldn't understand why you had a mountain under tension. In plate tectonic theory, we knew that if you had plates collide, it made sense: they would crush into one another, you would thicken the crust, you'd uplift it. That's why you get, you know, you get seashells up on Mount Everest. It's not a flood, it was pushed up there. We understood mountains under compression, but we could not understand why we had a mountain under tension. It should not be. Until one of my colleagues said, "It looks to me like a thermal blister, and the mid-ocean ridge must be a cooling curve." We said, "Let's go find out." We punched a bunch of heat probes. Everything made sense, except, at the axis, there was missing heat. It was missing heat. It was hot. It wasn't hot enough. So, we came up with multiple hypotheses: there's little green people down there taking it; there's all sorts of things going on. But the only logical [explanation] was that there were hot springs. So, there must be underwater hot springs.
