Why is it said that Mount Everest is not the highest peak and there are no 24 hours in a day?

First of all, the statement that Mount Everest is not the highest peak in the world is mainly a change of concept. Because in this statement, he thinks that the height he understands refers to the distance between the top of the mountain and the center of the earth. But in fact, in real life, we use sea level as the reference unit for the height of a mountain. Therefore, There is a saying that Mount Everest is the highest peak, and in this saying, the center of the earth is used as the reference unit.

With this reference, Mount Everest is obviously not the highest peak in the world, because the earth itself is not actually a round shape as we intuitively understand it. The true appearance of the earth itself is not round, but partially convex. If this is considered fair, then a mountain called Chimborazo in Ecuador with a height of only 626 meters is already higher than Mount Everest because of the distance between it and the center of the earth. The distance is more than a mile between Mount Everest and the terrain. But obviously this is a conceptual shift.

A day is actually not 24 hours. This is correct, because the reason why a day is set as 24 hours is to provide us with a more reasonable concept of time. In fact, there is no time in a day at all. 24 hours, even what we understand as 365 days as a year, is just a conceptual approximation of this much. In fact, a year is longer than 365 days, which is why we have a leap day every four years. Because every four years, the earth gets exactly one extra day. In fact, a year is actually about 365 days and six hours.

As for a day, to be precise, a day is actually only 23 hours, 56 minutes and four seconds. But in order to facilitate our simple use of time in daily life, a day is roughly regarded as 24 hours.
