Dark matter sends gravitational waves like visible matter. There may be two types of gravitational waves. The gravitational waves with ultra-short wavelength. And gravitational waves that have ultra-long wavelengths. The idea came into my mind because some galaxies seem to wave. If that thing is true, another gravitational effect can interact with the smallest parts of the material. Another long-wave gravitational effect can interact only with large material entireties. Ultra-accurate clocks search differences in time. And those differences would hope to make dark matter visible. In those ideas, the system tries to detect differences that dark matter can cause in time. So those systems measure time dilation. Researchers are interested in dark matter, because, it can open the road to complete gravitational models. When researchers try to create a gravitational model the key element is that the gravitation effect forms when some kind of radiation acts...
