Models are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by humans. What is a model?

A model is a representation of something that is often too difficult to display directly.

A model begins with an observation and question that the scientists will research, devise a hypothesis, experiment, and draws a conclusion.

A model is an explanation for patterns in nature that are supported by scientific evidence and verified multiple times by various groups of researchers.

A model is a representation that is used only in relativity and quantum mechanics since experiments cannot be done at such high speeds or on such small scales.
