Is it really impossible for human beings to feel that the earth is rotating at a speed of 400 meters per second?

On the equator, the linear speed of the earth's rotation reaches 465m/s, and the average linear speed is about 300 m/s, which is 1080km/h, and the average passenger plane can only reach about 900 km/h..

Living on the earth, we are spinning at the speed of the plane every day, but why doesn't anyone feel the rotation? Nobody "dizzy the earth"?

The rotating earth has no frame of reference: the earth is like a huge carousel, but unlike an amusement park, human beings can't see the external frame of reference.

Sitting on the merry-go-round in the amusement park, only the whole machine is spinning. We can observe things other than the merry-go-round, which will rotate in our eyes because of our rotation.

Observing rotating things for a long time, the brain will lose its sense of direction and lead to loss of balance.

The earth is like a giant carousel. Everything on the earth is riding on a merry-go-round, so everything in our field of vision rotates synchronously with us, that is, it is still.

To feel the rotation of the earth, we need to observe the reference system outside the earth, that is, other celestial bodies. But most celestial bodies cannot be directly observed by human naked eyes. Losing the reference line is like living in a closed carriage. If the vehicle is stable enough, we will forget that we are driving at high speed at this time.

If we shoot the stars with time-lapse photography, we will see the rotating orbit, which is one of the evidences of the earth's rotation.

The rotating earth is very stable: although it is difficult for human beings to regard other celestial bodies as the reference system on the earth, as a moving system, there is another way to feel the movement-inertia.

Just like when we ride a vehicle, if the vehicle accelerates or decelerates, we will be affected by inertia and our bodies will lean backwards or forwards. This inertia is another way for us to feel motion without a frame of reference.

Unfortunately, the earth's motion is very smooth, there is no "speed bump" in the universe, and the earth is basically in a state of uniform motion and uniform rotation, so our bodies will not feel any inertia brought by the rotation of the earth.

All the objects on the earth are following us in the same movement, which we can't perceive or influence. However, if the earth suddenly stops rotating, all objects on the earth will sprint at a speed of nearly 400 meters per second because of inertia, and even the atmosphere can't escape inertia, which will lead to a super "global storm".

Although we can't perceive the rotation of the earth, we can know that the earth has been rotating by observing the movements of the sun, the moon and the planets.
