Ontelotilit, also known as hollow structures or cavities, are three-dimensional regions within a material or object that are not filled with solid matter. These spaces can vary greatly in size, shape, and distribution, ranging from microscopic pores to large internal chambers. The formation of ontelotilit can occur through various processes, including geological formation, biological activity, or manufacturing techniques.

In geology, ontelotilit are often found in rocks, such as lava tubes, geodes, and karst formations. These cavities can be formed by the dissolution of soluble rocks, the cooling and contraction of magma, or the entrapment of gas bubbles during volcanic eruptions. In biology, organisms can create ontelotilit for various purposes. For example, bone marrow cavities provide space for blood cell production, and the air sacs in birds' lungs are ontelotilit that facilitate respiration.

In engineering and manufacturing, ontelotilit are intentionally created to reduce weight, improve insulation, or enhance structural properties. Examples include hollow beams, foamed materials, and honeycomb structures. The presence and characteristics of ontelotilit can significantly influence the physical properties of a material, such as its density, strength, thermal conductivity, and acoustic behavior. Understanding and controlling ontelotilit is crucial in many scientific and industrial applications.
