The law of gravity says that everything attracts each other. Newton fell from an apple and found that it was gravity, and I

Gravitation is directly proportional to the product of the mass of two objects, so the gravity of two objects in daily life is very small and people can't feel it, while the mass of the earth is very large, so the gravity of the earth to the objects on the earth is obvious. Meteorites around the sun do circular motion, and circular motion requires strong pulling force. Gravity plays this role, so it won't fall (to be exact, it is actually falling). Gravity exists between two objects with mass, and your knowledge level is not good enough to understand BIGBANG. I suggest you read more physics books and don't think blindly, or you will become a folk subject.
