Final answer:
The matter in the universe is composed of atoms, with 118 different types discovered so far, which combine in varied ways to create all forms of matter.
Step-by-step explanation:
The matter that makes up all things in the universe, no matter how different they seem, is composed of a limited number of building blocks known as atoms. To date, scientists have confirmed the existence of 118 different types of atoms. These atoms combine in various ways to create all the complex forms of matter we see around us. An interesting analogy is that it's similar to creating a diverse array of dishes using only a few ingredients. By understanding the combinations of these elements, we grasp how 118 atomic building blocks can result in the vast diversity of matter in the universe.
