Recent measurements of the expansion rate of the universe reveal that the expansion rate of the universe is doing something astronomers did not expect. What is that?
A) The measurements show that the universe may not be expanding at all. B) The measurements show that the universe may be shrinking rather than expanding. C) The measurements show that the expansion is accelerating, rather than slowing under the influence of gravity. D) The measurements indicate that the universe is at least 30 billion years old, meaning that more than 10 billion years passed between the Big Bang and the formation of the first stars and galaxies. E) The data show that the expansion rate varies widely in different parts of the universe.
