The statement "The sun is 93 million miles away" is an example of a fact.

Here's why:

* It's verifiable: We can use scientific instruments and calculations to confirm this distance.

* It's objective: It's not based on opinion or belief, but on measurable data.

* It's specific: It provides a precise measurement of the distance between the Earth and the Sun.

While the statement doesn't necessarily demonstrate a specific scientific concept, it's a fundamental piece of information about our solar system that is based on scientific observation.
