What Makes It Science? Choose one idea from the modern view of the cosmos as discussed in Chapter 1 (such as “The universe is expanding” or “We are made from elements manufactured by stars”.)

1. Describe how this idea reflects each of the three hallmarks of science, discussing how it is based on observations, how our understanding of it depends on a model, and how that model is testable.
2. Describe a hypothetical observation that, if it were actually made, might cause us to call the idea into question. Then briefly discuss whether you think that, overall, the idea is likely or unlikely to hold up to future observations.
