Any entity capable of interstellar travel will possess the ability to harness energy in ways that are almost impossible for us to imagine. If they transit space rapidly (on a human scale) they will be able to discharge energy in amounts so vast as to be incomprehensible. If they transit space slowly (on a human scale) they will be able to store energy in amounts so vast as to be incomprehensible. They'll be able to pluck individual hydrogen atoms out of the vast emptiness of interstellar space and reconstitute them into any element whose existence is possible. They'll be able to generate and arbitrarily manipulate gravity. They'll be able to approach, disassemble, store, and reassemble entire stars. They won't be lazily floating in a car-sized object above the Canadian wilderness, bouncing around in the jet stream.
