Think about Earth. The oceans. The mountains. The forests. The millions of forms of life. Thunderstorms. Volcanoes. Snow. Our history, including past civilizations and enormous monstrous dinosaurs.
Add in the possibility of multiple, or even infinite dimensions, which means entire civilizations could exist on a planet like Earth right alongside us without us knowing it, throw in the nature of time and time travel as it interacts with gravitational forces like black holes, and the concept exceeds the human mind’s ability to grasp.
