Answer: B. Why are stars clustered together and not spread uniformly throughout the universe?
The big bang theory claims that the universe we observe is created out of single point or singularity which exploded or there was a big bang which led to formation of universe. The universe is expanding since then and will end in coldness one day. Then why the stars get cluttered and not spread out uniformly after the explosion. This remains unexplained in the Big bang theory.
