For as long as humans have looked up at the night sky, we have wondered if we are alone. In 'Brief Answers to the Big Questions,' Stephen Hawking brings this ancient question into the realm of science. He points to the rapid appearance of life on Earth and the discovery of thousands of exoplanets as evidence that life may be common in the universe. The blog explains how modern astronomy has transformed the search for aliens from fantasy to a rigorous scientific pursuit. Hawking discusses the Fermi Paradox—the puzzle of cosmic silence despite the apparent likelihood of life—and offers possible explanations, from the rarity of intelligence to the vast distances between stars. He also warns that contact with advanced civilizations could be dangerous, drawing on historical examples of encounters between cultures on Earth. Despite these concerns, Hawking remains hopeful, seeing the search for life as a celebration of human curiosity and imagination.
This blog invites readers to join the quest, not just as scientists, but as dreamers, explorers, and citizens of a vast and mysterious cosmos.
