How is matter best defined?

The definition of matter as "anything that has mass and takes up space" is fundamentally accurate because it encompasses all physical substances found in the universe. Matter encompasses everything that occupies a volume and has weight, regardless of its state (solid, liquid, gas). This definition is crucial in the field of science as it allows for the understanding of both visible objects and substances in various forms.

This distinction is significant because while the other options contain elements that may describe aspects of matter, they do not encapsulate a comprehensive definition. For instance, energy is a separate concept and does not define matter. Additionally, matter does not need to be visible or tangible in order to exist; gases, for example, occupy space and have mass but may not always be seen. Furthermore, limiting matter to substances found on Earth excludes the vast universe of matter that exists in space, such as celestial bodies and interstellar gas. Thus, the definition provided as the correct answer accurately reflects the core characteristics that define matter.
