Is Mount Everest really the tallest mountain on Earth?

Transcript

If you thought the tallest mountain on earth is Mount Everest, you're wrong and I have a lot to teach you about human beings. You see Everest's peak is the furthest above the sea, almost 9 km up but that's how we usually measure mountains. But if you measure a mountain from its foot all the way to its top, the tallest one is Mount Akiha in Hawaii at more than 10 km. And most of us have never heard of it because it starts on the floor of the Pacific and more than half of it is under the sea. So measured from sea level it looks less than half a stall is Everest and Everest gets a head start. It rises from the edge of the Tipitian plateau which is already more than 4.5 km up. And I think we measure people the way we measure mountains from sea level, from wherever everybody else happens to be standing. So the one who started on the plateau looks like a giant and the one who started on the ocean floor looks half the size. If you're the first person in your family to do what you're doing, a lot of your climb happened under the water where nobody was counting. So measure yourself from the sea floor because from down there you might already be taller than Everest.
