<span>That the mass is far lesser and distributed mistakenly, as compared to what the orbits of stars declare it should be. Stars orbit more rapidly than the mass would predict, particularly out toward the galactic edge. This means that there is more mass than has been measured, and that it is spread out in a huge cloud around the galaxy. This is one of the reasons why scientists believe that dark matter exists.</span>

Is matter continuous and therefore has no finer structure or is it discontinuous and thus made or tiny particles

Marta_Voda [28]

Matter is discontinuous, and it is made of tiny particles called atoms

Explanation:

Matter is not a continuous structure, but it consists of tiny particles called atoms.

An atom consists of three types of particles:

Proton: the proton is in the nucleus of the atom. it has a positive electric charge of $+1.6\cdot 10^{-19}C$ (also called fundamental charge). Its mass is $1.67\cdot 10^{-27}kg$ .

Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.

Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to $-1.6\cdot 10^{-19}C$ . Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
