Matter
Matter, the fundamental substance composing the universe, holds a central position in the realms of physics and chemistry. Defined as anything that occupies space and has mass, matter encompasses a vast array of forms, ranging from atoms and molecules to planets and stars. Understanding the properties and behaviors of matter is essential for comprehending the nature of the physical world, from the microscopic interactions of particles to the macroscopic phenomena observed in everyday life. In this introductory exploration, we delve into the diverse nature of matter, examining its composition, structure, and significance in shaping the fabric of existence.
