There is nothing up or down in space. Such questions are normal. Because, all the objects in space-time are located in space. The sun or such a huge object gives a curved shape around it in this space-time. As a result, the earth or other planets are attracted to the sun.
In fact, under the influence of the gravitational ball, the sun is pulling the earth towards it. As the world is pulling. That is, there is no such thing as the earth moving up or down in space towards itself. Such questions are normal. Because, all the objects in space-time are located in space. The sun or such a huge object gives a curved shape around it in this space-time. As a result, the earth or other planets are attracted to the sun.
In fact, under the influence of the gravitational ball, the sun is pulling the earth towards it. As the world is pulling. That is, the world pulls everything towards itself. That is, the earth has an invisible force of attraction. Because the earth pulls everything towards itself, something falls down without going up. In the same way the earth is pulling the moon towards it. The question is, why is the earth not falling into the sun or the moon is not falling on the earth? Why are you walking around?
The answer is that the earth is always falling towards the sun, but cannot fall. Because, he is spinning so hard that every moment he wants to get away from the sun, but he is constantly attracted to the sun by the effect of the gravitational ball. Due to the effect of these two balls, he is bending a little bit at every moment and turning in an almost circular way. So we can say that the earth is actually falling towards the sun, but in an elliptical way. In the same way, the moon is always falling towards the earth, but due to the effect of the gravitational ball, it is constantly being attracted towards the earth.
