Through continuous research by scientists, they found that there are four basic forces in nature, namely gravity, electromagnetic interaction, weak interaction and strong interaction. The existing scientific level of human society can not only explain the reasons for the existence of gravity, but also solve the reasons for the formation of electromagnetic interaction, weak interaction and strong interaction. Talking about these four basic forces, the oldest one is gravity, and the other three basic forces are all transformed from anti-gravity due to a series of changes after BIGBANG.
These four basic forces actually exist in unity, and physicists usually study and explain them together. Although there is no complete explanation for the cause of gravity, there are still some assumptions in the scientific community. Scientists have discovered that the interaction between stars in the universe emits gravitational radiation, so they speculate on its existence? Gravitator? This substance. They believe that there is interaction between substances because there is an interaction between substances called? Gravitator? The basic content of. Unfortunately, so far, people haven't found it? Gravitator? The existence of matter.
Of course, the scientist's hypothesis is only a theory, and a lot of practice is needed to prove whether the theory is correct. But I believe that one day scientists can fully understand the reasons for the formation of the four basic forces.
