For example, no new evidence will demonstrate that the Earth does not orbit around the sun ( heliocentric theory ), or that living things are not made of cells ( cell theory ), that matter is not composed of atoms, or that the surface of the Earth is not divided into solid plates that have moved over geological timescales ( the theory of plate tectonics )... One of the most useful properties of scientific theories is that they can be used to make predictions about natural events or phenomena that have not yet been observed.
