Abstract

For more than 30 years, the author of this paper has discovered the existence of the matter unknown to people in the study of some special photos. This matter is extremely different from the matter known by modern science. The author of this paper temporarily names this matter y-matter. In contrast with y-matter, the matter known by modern science (macroscopic matter, microscopic matter) is called x- matter. In this paper, a number of photos are provided to show the existence of y-matter. In the photos, the objects composed of y-matter (y-objects) are seeable in the photos but were invisible to the naked eye when the photos were taken. In modern science, the substances that are invisible to the naked eye but can be photographed include x-rays, infrared rays, ultraviolet rays, etc. However, the y-objects shown in the photos in this paper do not belong to these substances. Y-objects can react chemically with the substances on the camera film, so y-objects are indeed made of matter. This paper then discusses some physical properties of y-matter. Y-objects have no static mass and no momentum. They have density and motion. The maximum speed of the movement can exceed the speed of light, etc. This article first uses photos to show the movement of a y-matter object. Then, this paper explores the relationship between y-matter and thinking. People can use thinking to move certain y-objects under certain conditions. The research in this article opens up the unknown world of matter, which will change human concepts and promote the epoch-making development of science and technology. The future research is to study the conditions under which y-objects can be photographed.
