Your review of Alex Vilenkin’s book Many Worlds in One: The Search for Other Universes, above, contained an often-made error. In Guth’s inflation model, during the first “zillionth of a second,” the universe did not inflate “to cosmic scale.” It inflated to about the size of a large grapefruit. Then it began its slow expansion.
