The Vast Opportunities Await
The questions posed lead to further contemplation of the potential distance humanity could explore. Arthur argued that within a billion light-years—or beyond—claims of new worlds could be made if they present no prior intelligent life. Yet he also acknowledged humanity's evolving technological landscape that may produce breakthroughs in propulsion systems, unlocking previously unimaginable possibilities.
Ultimately, Arthur underscores that the spirit of exploration should be present in humanity’s future. Should we discover a lack of existing civilizations in the vast galaxies waiting to be explored, he states a compelling question should arise: Why wouldn’t we?
