Democritus devised and atomic theory and presented the idea that everything was made up of smaller indivisible objects.
His theory states:
- Everything is composed of “atoms”, which are physically, but not geometrically, indivisible
- Between atoms, there lies empty space
- Atoms are indestructible
- Atoms have always been, and always will be, in motion
- There are an infinite number of atoms, and kinds of atoms, which differ in shape, and size.
