ABCD

[[A child and an adult are walking across a grassy park with puddles strewn across it and trees nearby.]] Child: What was before the Big Bang? Adult: I think time began with the Big Bang. So it doesn't make sense to ask what came before it. From offscreen: Look out! [[A cosmologist on a tire swing comes swinging by the pair.]] Cosmologist: Wheeeee hi I'm a cosmologist on a tire swing! [[The cosmologist swings back the other way.]] Cosmologist: We don't know whether time-- [[Another swing the other direction...]] Cosmologist: --started at the Big Bang. [[Another swing.]] Cosmologist: It might have! [[Another swing.]] Cosmologist: Or maybe not! We don't know! Adult: Oh. Ok! [[Another swing.]] Child: ...your tire swing looks fun! Cosmologist: I can't stop! [[Continues swinging.]] Child: Won't the swing stop on its own? Cosmologist: I thought it would but it seems to be accelerating. Child: Cosmology sounds pretty confusing. Cosmologist: Wheeeee! {{Title text: No matter how fast I swing, I can never travel outside this loop! Maybe space outside it doesn't exist! But I bet it does. This tire came from somewhere.}}
