Are We Alone?
Mythology and religious texts are rich with descriptions of beings from other worlds. The search for other worlds, not only the physical planets but the intelligent beings that might inhabit those places, is a scientific enterprise similar to space exploration; however, that journey begins in our mind. This planet, with a 4 billion year history, is a speck in a cosmic ocean with vast shores that we haven’t seen yet. Our ships can’t cross this immense ocean, but our imaginations can, and that journey may be more exciting than the destination. Should we continue our efforts to detect intelligent beings? Experts differ, and many describe this process as similar to looking for a needle in a haystack, which in fact has better odds.
