Multiple Choice
The early universe was characterized by a much lower metal content than the present universe. What difference did that make to the process of star formation?
A) The first generation of stars had lower metallicity than the present generation, but in each era the formation of large stars and small stars was equally likely.
B) It is easier to make a gas and dust cloud collapse when the metal content is low. Thus, even small stars could be formed in the early universe, but large stars were a rarity.
C) It is harder to make a gas and dust cloud collapse when the metal content is low. Thus, even small stars could be formed in the early universe, but large stars were a rarity.
D) It is harder to make a gas and dust cloud collapse when the metal content is low. Thus, large stars were more likely to be formed in the early universe, but small stars were a rarity.
