For our earth, it has a history of billions of years. In this long history, we have achieved some natural laws, and these natural laws are what we can do every day. For example, what we call gravity is still the same, and some people have asked gravity: there is gravity on the earth. What is the principle of gravity? In fact, the principle of gravity comes from gravity. Write it separately below.

Why are there so many creatures on our earth? In fact, it is also because of our unique natural environment and survival rules. For example, gravity is as we know it. Because of gravity, there are so many differences on our earth. As far as we know, this creature exists only on our earth. The natural survival of these creatures has also brought a lot of vitality to the earth, which has formed us.

To tell the truth, gravity has also brought us many benefits. If you want to tell us what the specific benefits are, I may not believe it, so I will talk about the specific benefits from the opposite side. We can think about this problem from another angle. For example, if we say that the earth has no gravity, those problems are the same.

If there were no gravity on the earth, it would be difficult for us to do many things we do today. Presumably, at that time, it would be difficult for us to walk freely on the ground, and the cars on the ground would lose their original value, so it would be impossible for us to go out to play in the car that we use the most now. At that time, we humans floated freely in the sky. Under such circumstances, many new industries would be born. At that time, the most likely means of travel was the plane.
