If the earth spins at over 1,000 km / h, why don't we get dizzy?

Anyone who has rotated many times, stopped and tried to walk knows well what it is to feel dizzy. The same sensation may appear when we change position quickly and some people also feel dizzy from the rocking sea.

But none of these situations can compare to Earth's movement, which rotates at a speed of up to 1, 700 km / h in the Ecuador region. So how do we not feel dizzy or unbalanced if the planet is moving at such a high speed?

El Mundo points out that, according to Antonio Ruiz de Elvira, professor of physics at the University of Alcalá in Madrid, Spain, dizziness is a side effect of a mechanism we have in the body and serves to maintain our balance in the three dimensions. . Such mechanism is formed by the semicircular canals that are connected between the ears.

Whenever we move our head slowly, the body records this change and triggers different muscles so that we can stand upright. But if the movement is too fast, the brain does not know which signals to send and we may end up falling for lack of muscle coordination.

The professor still remembers the physics classes and points out that the movement, as stated by Galileo and Eistein, is relative, that is, it has meaning only when it is related to another immovable point. The expert further exemplifies our relationship with Earth from a plane trip:

“On a plane, at night and without turbulence, we don't know that we are moving. The same is true of the earth: to our ears we stand still, for everything around us moves with us. ”
