What are the Great Walls?
Q: What are the Great Walls?
A: The Great Walls are the largest known structures in the universe.
Q: How were the Great Walls mapped?
A: The Great Walls were mapped based on a data set mapping of gamma-ray bursts (GRBs).
Q: What did the mapping find about the Great Walls?
A: The mapping found an unusually high concentration of similarly distanced GRBs in certain areas.
Q: How large are the Great Walls estimated to be?
A: Structures larger than 1,200,000,000 light years are incompatible with the cosmological principle according to all estimates.
Q: Why are the Great Walls significant?
A: The Great Walls are significant because they are the largest known structures in the universe.
Q: What is the cosmological principle?
A: The cosmological principle is the assumption that the universe is homogeneous and isotropic on large scales.
Q: How do the Great Walls relate to the cosmological principle?
A: The Great Walls are relevant to the cosmological principle because structures larger than 1,200,000,000 light years are incompatible with it according to all estimates.
