Universal repulsion is a special existence of gravity. The existence of gravity has been proved by scientific experiments, and it does exist. As the opposite of gravity, repulsion also exists.

As we all know, there is gravity? An apple? From this, Newton thought of the existence of gravity, which opened the curtain of classical physics. This is not only a great discovery of physics, but also a big step forward for human beings to develop science. After Newton and his later scientists constantly supplemented classical physics, the mistakes and shortcomings in classical physics tend to be more complete and develop in a systematic direction.

The key word we mentioned above is gravity, so what is gravity? Gravitation: As the name implies, it is the gravitational force that is often mentioned in life, and the full name in science is called gravitational interaction. The reason why gravity is unpredictable is that among the four basic interaction forces, gravity is the most thoroughly known and understood by human beings. Gravity is mainly manifested in the macro aspect, and rarely involves the micro field. Gravity surrounds us all the time, and it also belongs to the range of long-range force. ? The most intuitive thing is the celestial bodies in our sky. The movement of celestial bodies is very mysterious. In today's words, it is something tall, so we think it is very important.

Gravity, in the final analysis, is the interaction between matter and space-time, which is clearly expounded in the theory of relativity. The range of space-time disturbance tends to be infinite, and the acting distance of each substance as a source of gravity is also limited, not without any restrictions. For example, we can take the strength ratio as 1, the weak force as 10- 13, the electromagnetic force as1137, and the common gravitational force as 10-39. We can understand the difference between gravity and the other three forces.

According to the above facts, universal repulsion also exists, maybe we haven't found it yet.
