So little of the physical universe is made up of the sort of material of which we think reality is made. Indeed 96% of it consists of dark matter and dark energy. And of the 4% made of “matter” as we ordinarily understand it, only a tiny sliver reflects visible light. Yet our ideas about what can or cannot be “out there” are often based on our minuscule exposure to the visible part of the universe. And we assume that whatever might be “out there,” where we cannot see anything, surely must be insentient. But what if we are wrong? What if there are intelligences “out there” that are not visible to us? Posing that question raises five further questions.
