What is the Shapley Supercluster?
Q: What is the Shapley Supercluster?
A: The Shapley Supercluster is the largest concentration of galaxies in our nearby universe.
Q: How far away is the Shapley Supercluster?
A: The Shapley Supercluster is 650 million light years away from us.
Q: What is the meaning of z=0.046 mentioned in the text?
A: z=0.046 is a redshift value that indicates how much the universe has expanded between the time the light was emitted from the Shapley Supercluster and the time it reached us.
Q: How does the Shapley Supercluster behave in relation to the expansion of the universe?
A: The Shapley Supercluster is an overdensity in the distribution of galaxies that pulls itself together due to gravitational interaction, instead of expanding with the universe.
Q: Which constellation is the Shapley Supercluster located in?
A: The Shapley Supercluster is located in the constellation of Centaurus.
Q: What is the significance of the Shapley Supercluster in terms of the study of the universe?
A: The Shapley Supercluster provides insights about the large-scale structure of the universe and the distribution of galaxies.
Q: How does the existence of a supercluster like Shapley impact our understanding of the universe's origins?
A: The existence of a supercluster like Shapley suggests that the universe had regions of higher density in its early stages, which led to the formation of galaxy clusters and superclusters. This information helps in building models of the universe's evolution.
