If the world has no gravity

The home of our common humanity - how wonderful the earth is. The reason why we live on the earth, the reason why we will stand in every corner of the earth steadily is gravity.

Ever since listening to my father, Newton’s apples falling from the apple tree have found the earth to be gravitational. I began to wonder: What if the earth has no gravity? After my hard thinking, I imagined two possibilities for the Earth to be gravitational:

One. People walk problems. When the earth has no gravity, we will become very difficult to walk. For example, if you want to go home, you can't familiarize yourself with the flying skills, and you will fly to other places without knowing it. You will fly to the United States, South Korea, France... Hey, the horror is dead!

two. Natural problem. When the earth loses its gravity, people will fall into space from the earth, and animals will fall from the earth; the sea will rise and float, and the whole universe will float. The steel of the factory will also rise with the sea; of course, the computer also Will drift into the universe...

Oops, what should I do? The computer flew, how do I write an essay on the Internet! Oh, I want to fall from the earth! Friends, hurry up and pull me up!
