Mount Everest no longer world’s highest mountain
Which is closer to the surface of the moon, the summit of Mount Everest or Ecuador?
Contrary to popular belief, the answer is Ecuador, as the Earth isn’t a perfect sphere. As the Earth is constantly spinning, centrifugal force causes it to bulge out at the equator much like a water balloon would if you placed it on a table and pressed on the top.
Let’s look at Mount Chimborazo in Ecuador. The summit of Chimborazo is 6,267 m (20,561 ft) above sea level, which is quite large but not quite the highest mountain in the Andes. If you take into account the Earth’s equatorial bulge, a straight line from the summit down to the estimated centre of our planet would be 6,384.4 km (3,967.1 mi).
Now look at Mount Everest, widely known as the tallest mountain in the world. The summit of Everest is 8,848 m (29,029 ft) above sea level, but a straight line from the summit to the centre of the Earth would only be 6,382.3 km (3,965.8 mi).
So even though the summit of Chimborazo is about 2,400 m closer to sea level than Everest, it’s still 2,100 m further away from the centre of the Earth! By this logic, three more mountains (Huascaran, Cotopaxi and Kilimanjaro) around the world are actually “higher” than Everest as well.
Sadly our newly defined rules aren’t taken into account when deciding on the world’s highest mountain, so although Chimborazo is ranked the highest in distance from the centre of the Earth, Mount Everest still wins since we always measure to sea level.
If you’re a climber and neither one these appeals, you could always try Gangkhar Puensum in Bhutan. It’s considered the highest unclimbed mountain in the world1.

Which is probably something to do with the fact that climbing mountains higher than 6000 m in Bhutan has been prohibited since 1994, out of respect for local spiritual beliefs. ↩
You could also argue that it is in fact Mauna Kea that is the highest peak on the planet with a height of about 9100 meters from the sea floor

And every place on the equator is closer to the moon than someplace away from the equator, because the moon circles the equator (more or less).
You could dig a big pit next to any big mountain and say it’s higher from the bottom of the pit to the mountain top than Mauna Kea, doesn’t make it record worthy. It’d go with closer to space (Mt Everest, assuming I’m right about the atmosphere being of equal depth all over Earth) or furthest from core.

there is distinction between the tallest and highest. tallest being from base to summit. highest is a measurement of highest point. How can you define the centre point of the earth as a datum. you have to use sea level and therefore Mount Everest is the highest
But if datum is sea level, as the tide changes so does datum……….. some places more than others….
Sea level is not affected by tides.
Sea level is … MEAN sea level isn’t.
How can you define the sea level as a datum.[?] you have to use centre point of the earth and therefore Mount Chimborazo is the highest

interesting post, and interesting discussion as well, but overall not worth arguing about.
I was taught that a mountains height was the distance between its peak and sea level not the distance between the peak and reality.
