The Fermi Paradox asks the question: If life is common in the Universe, why has humanity yet to find any evidence of it?
The Fermi Paradox asks the question: If life is common in the Universe, why has humanity yet to find any evidence of it?As famed scientist and science communicator Arthur C. Clarke once said, “Two possibilities exist: either we are alone in the Universe, or we are not. Both are equally terrifying.
Years later, the story was used to frame the debate regarding SETI efforts and whether or not they are worth the time, energy, and resources dedicated to them. Specifically, scientists Michael Hart and Frank Tipler argued that the answer to the paradox was simple: humanity is alone in the Universe. Over time, many proposed resolutions have been offered that go far beyond the Hart-Tipler Conjecture, and the debate as to which is most likely continues.
Alternatively, an advanced species could have developed these probes to wipe out any intelligent life that might be seen as a potential threat. In this scenario, the hostile probes are the “filter.” As Dr. Hanson told“The great filter is whatever obstacles stand between simple dead matter eventually giving rise to a distantly visible civilization. The more of this filter that we have already passed, the greater our future chances.
