Who is Granny Bb'b from Cosmicomics and what is their importance?

Granny Bb'b appears in the story, At Daybreak. She remembers the early days of the universe, when the universe was filled with a diffuse light, and she believes that matter will disperse again and that the early light and heat that radiated throughout space will return. She believes so emphatically that she even throws garbage into space, believing that it will simply break up and go away. Qfwfq finds Granny's beliefs and actions to be embarrassing.
