Scientific discoveries have given us a much better understanding of the world. Can you imagine that when an acrylic sheet is tapped by hand, the generated electromagnetic field can produce a voltage of 3600 V? The general theory of relativity predicted the existence of gravitational waves. Here, we found that two objects can generate electromagnetic fields under forces, and high frequency interaction can generate electromagnetic waves. We have deduced that gravitational waves generated by the collision of celestial bodies are the same as the electromagnetic field generated by the collision of small stones. When two small stones collide, the generated electromagnetic field can drive the LED. Wind blowing objects was used to verify that there would be electromagnetic field generated by friction between the object and atmosphere. We speculate that there must be super strong electromagnetic field produced by the friction between the earth surface and atmosphere because of the ultra-high-speed rotation and revolution of the earth. The electromagnetic field generated by friction between the fiber cloth and air can drive 1350 LEDs wirelessly, which indirectly verifies that how strong the electromagnetic field generated by the rotation of earth will be. The generated energy radiates outward in the form of electromagnetic waves and is distributed throughout the out space. This may lead to the formation of earth's ring-shaped gravitational waves. On this basis, it is inferred that the gravitational waves should exist anywhere, anytime and in everything. In addition, several power generation devices including self-powered board for portable devices were designed based on the discovery. These new findings will have far-reaching impact on a range of research fields such as physics, new energy and astronomy.
