Refuting that we move with the earth, there is no reference, so there is no feeling. Man's sense of motion is formed in this way: for the sense of linear motion, man's sense of uniform motion depends on the change of his relative position with other objects. For example, if you are on a high-speed rail, there is a high-speed rail running at the same speed on the next track. If you look at him, you will feel that you are standing still. The shell and the earth are in an inertial system, which has the rotation speed of the earth, so it will fall near its original position.
Answer: When people are blindfolded and sitting on a high-speed rail or plane moving at a constant speed, they really don't feel that they are moving. This statement makes sense. But the movement of the earth is rotation, not variable speed. Why can't you feel it?
It is retorted that people rely on the change of their relative position with other objects and the feeling of their bodies to perceive the linear motion with variable speed. Because the angular velocity of ordinary objects around us is the same as ours, we can't judge the movement of the earth from them. Moreover, the speed change brought by the earth's rotation is also very small, so people can't judge whether they are rotating according to their own acceleration. Humans can feel themselves spinning, but if the angular velocity is too small, people can't notice it. Because the angular velocity of the earth is too small for people to detect. But humans can infer the rotation of the earth by observing the movement of celestial bodies in a way that the brain understands.
Answer: For variable-speed linear motion, the stop and start of subway can be used as a simulation. When the train starts or arrives at the station, it will change speed, but as long as there is a little speed difference, there is no need for a frame of reference, and human beings can feel it. What's more, the earth is by no means a simple linear motion with variable speed. The earth in reality is not as simple as a merry-go-round, but has been riding a roller coaster, as shown in the figure below. This is a simulation diagram given by scientists, not invented by me personally. The trajectory of the earth's revolution around the Milky Way at a speed of 250km/h is snake-shaped, not a uniform circular motion, but a snake-shaped variable-speed motion (I don't know how to describe it accurately, just describe it like this ...). All directions are powerful in supporting everything on the earth, which is equivalent to. We've all been on roller coasters. Excuse me, wouldn't you feel if a trafficker blindfolded you and tied you to the seat of a roller coaster? This doesn't need a reference frame at all! As long as your emotional feeling is still there, you can feel it! In addition, there is another reason why high-speed trains and airplanes can't simulate the earth's motion, that is, there is no rigid connection between the crust and the atmosphere, and the mass of the crust and the atmosphere is very different from that of the air, which determines that their inertia cannot be the same. Then, why didn't the super-high-speed rotation of the earth form the speed difference between the crust and the atmosphere, which led to the super typhoon? In addition, we should know that many elderly people with heart problems can't take the super high-speed rail, let alone the super high-speed roller coaster, so why can the hearts of those elderly people withstand the variable-speed movement of 250km/h? Why didn't they die suddenly?
