Question

should all models be \to scale\? yes - otherwise it is not accurate no - some things are too big or too small to see.

Explanation:

Some real - world objects are extremely large (like planets) or extremely small (like atoms). Creating a to - scale model for such objects is often impractical or impossible due to limitations in space and visibility. For example, a to - scale model of the solar system would require an enormous amount of space.

Answer:

No - some things are too big or too small to see.
