Why Does it Seem Like we are Alone in the Universe? What is the Fermi Paradox and the Great Filter?

The great astronomer Carl Sagan once spoke for wanderers across all borders, ethnicities, races, and religions, when he said. “We were wanderers from the beginning. We were bounded only by the earth, and the ocean, and the sky. The frontier was everywhere.” Humanity’s addiction with exploration and wonder is intrinsically tied to our nature. Our dauntless exploration is a testament to our nature; to survive, we must explore new worlds. When the drought was prolonged, or when the food was scarce, we moved on. We wandered throughout our terrestrial planet, searching for survival. We were hunters and foragers, explorers of the unknowns. We were voyagers, adventurers in the mountains and on the oceans. As we grew more advanced, we began voyaging the seas. We wandered across the Atlantic Ocean, we explored the Western Pacific, we circumnavigated Africa, and we ventured throughout the Americas. Many of our great explorers, like Ferdinand Magellan, Zheng He, Marco Polo, Henry the Navigator and John Cabot explored worlds we once did not know existed. We continued on in our advancement, and eventually reached space. We indulged in a new chapter of human existence; we were now a part of the cosmos, rather than a part of the planet. Now that we are advanced enough to look at and explore the heavens, we wonder if we are really alone. The universe is exponentially larger than we had previously known, and exponentially more divine and incredible. Even through all our intense exploration and search, we have yet to find any evidence of intelligent extraterrestrial existence. In a universe so vast and massive, it is daunting to imagine the prospect of loneliness within the universe. Arthur C. Clark spoke of humanity’s desperate urge for a cosmic partner when he said, “Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying.” Our desperate search for extraterrestrial life can be potentially well represented by the Fermi Paradox and the Great Filter.
