Type 2 civilizations, like in Star Trek, play with the colonizer solar system. Type 3 civilizations, like in Star Wars, roam the galactic space lane and engage with black holes. But a 10-year-old boy insists there is a type 4 civilization: the Q in Star Trek. The energy of this type 4 civilization is dark energy, which is even more powerful than galactic energy and is associated with the Big Bang and expanding universe.
