What consequence arose from Walter Baade's identification of different types of Cepheids?
Answer
A doubling of previous distance estimates to nearby galaxies.
Walter Baade's discovery that there were distinct types of Cepheids (Population I and Population II) revealed that the distant ones were intrinsically brighter than initially assumed, leading to a doubling of prior distance estimates.
