Yes, i did know that. The reason none of are dizzzy is because we are moving at the same speed as and share the SAME momentum as the ground we are standing. The cochlea of our ears have the same momentum too. That is why we do NoT get dizzy unless we spin around in circles which changes OUR momentum relative to the Earth's momentum , so we get dizzy. Dark matter and dark energy have NOTHING to do with why we do not get dizzy.
"...hy don't we feel Earth move?
Earth moves very fast. It spins (rotates) at a speed of about 1,000 miles (1.7 kilometers) per hour and orbits around the sun at a speed of about 67,000 miles (107,000 kilometers) per hour. We do not feel any of this motion because these speeds are constant. The spinning and orbital speeds of Earth stay the same so we do not feel any acceleration or deceleration. You can only feel motion if your speed changes. For example, if you are in a car which is moving at a constant speed on a smooth surface, you will not feel much motion. However, when the car accelerates or when the brakes are applied, you do feel motion...."
