Consider the following hypothetical observations, some of which are real and some of which are fictional. for each observation, your job is to answer this question: if the observation were real, would it provide evidence for or against the idea that the universe is expanding? sort each observation into the appropriate bin as follows:
a. place an observation in the "supports the expanding universe" bin if it would provide evidence that the universe is expanding. b. place an observation in the "contradicts the expanding universe" bin if it would provide evidence that would force us to reconsider the idea of an expanding universe. c. place an observation in the "neither supports nor contradicts" bin if it does not allow us to distinguish between a universe that is expanding and a universe that is not expanding.
