It always seems we have a certain bias when it comes to imagining alien civilizations more advanced than our own and that their energy needs would somehow be the same, similar, or greater than our own. Ignoring gravitational differences of various potential origin planets and the energy requirement differences to get into orbit based on a given planet’s gravity fields...what if the beings themselves were many orders of magnitude smaller or larger (or both for that matter). Even here on earth imagine some other beings with all the capabilities as us but could essentially stretch their arms upward and place little old us into orbit without the need for propulsion, or other beings so microscopic we could never be capable of detecting them even if they had the capability of building craft that could escape Earth’s gravity field.
