Although related, astronomy focuses on observing celestial objects, while cosmology examines the universe as a whole.
2. Confusing Cosmology with Cosmogony
Remember:
- Cosmology = the study of the universe.
- Cosmogony = theories about the universe’s origin.
3. Overusing Technical Terms
Avoid replacing every instance of cosmology with highly specialized alternatives if your audience is general readers.
4. Ignoring Context
