- QUESTION 10 What curvature will the universe have if the matter and energy density of the universe is equal to the critical density? Open Closed Flat O None of the above QUESTION 11 Why can you not observe beyond the horizon distance? O Because of opaque gas O Because our telescopes are not powerful enough O Because light/information cannot travel faster than the speed of light O Because of the of black holes QUESTION 12 According to the Olber's Paradox, the night sky should be completely bright. However, when we observe at night, the sky is dark. Why does this happen? O Because the universe has a finite age O Because as the universe expands, objects at larger distances move faster, and the light from them shifts out of the visible part of the electromagnetic spectrum O Both a) and b) O Neither a) nor b)What is the point of view on the topic of parallel universes and black holes?
