The question that occurs to me much later is what are the naturally occurring phenomena that hint toward these physics? As far as I know, as an interested layman, is that all experiments can be equated to events happening somewhere in the universe. Everything from black holes to supernovas act like massive particle accelerators. Are their any hypothetical situations that are similar?
