1. If some unknown cause of red shift-such as light becoming "tired" from traveling long distances through empty space-is discovered, what effect would there be on cosmology?

2. Olbers's paradox poses an interesting question: If the universe is infinite, then any line of sight should eventually fall on a star's surface. Why then is the sky dark at night? Discuss the commonly accepted evolution of the universe as a solution to this paradox.
