The Earth has been moving at high speed, why are humans unaware of it?

As earthlings, it is easy for us to believe that we are stationary. After all, it is difficult for you to intuitively feel that the earth is moving at high speed in the universe. But if you are smart enough and have the patience to observe, you can still easily infer that the earth is moving. Just like sunrise and sunset, or you look up at the starry sky, the stars are somewhere in the first half of your life, and they are somewhere in the second half of your life.

During the Earth's revolution and rotation, due to the effect of gravity, humans and other creatures on Earth cannot feel the movement of the Earth. But do you know that in fact, when the Earth revolves around the sun, the Earth's movement speed is very fast, moving more than 200 kilometers per second. But when you look at the stars at night, you find that the stars do not change at all. Why is this? Let us give a detailed introduction to it below.

In fact, this problem is well solved because the universe is really huge. As we all know, the stars we see in the night sky are very far away from the earth, some of them are even thousands of light years away from the earth. Although the earth is flying very fast in our eyes, at such a long distance, this speed is like a turtle shell.

As we all know, the Earth orbits once a year, so the Earth's speed is pretty fast. In addition, the solar system itself is also moving and will orbit the galaxy. There is a supermassive black hole at the center of the galaxy, and all the galaxies in the galaxy orbit around this core. Data shows that the solar system orbits the Milky Way every 200 million years, which is why the position of our planet has not changed.

Of course, this is also related to the level of human technology. Human space exploration has not made much progress because the speed of human spacecraft is limited and cannot support long-distance flights. In the vastness of the universe, there are many galaxies like the Milky Way, and the universe is still expanding. Therefore, for humans, the universe has no boundaries.

According to scientists, the universe is expanding very fast, even faster than the speed of light, so astronomers will find that some planets are moving away from the earth. But in the northern region, there is a very bright star, which people call the North Star. As we all know, the North Star is in the same position throughout the year and there is almost no change.

In fact, the North Star is also moving, although it is too far away for humans to see its movement with the naked eye. Therefore, the galaxies in the universe seem to follow certain laws of motion. After research, scientists have discovered that human physics actually applies to galaxies in the universe, so many astronomical phenomena have reasonable explanations, but it also requires humans to continue to develop and progress, only in this way can we understand the universe more deeply.
