Lee Billings on the Search for Life in a Silent Universe
It’s a big cosmos out there. It wasn’t too long ago that we couldn’t be sure that any planets existed anywhere outside of our own solar system. But in just the past handful of years, we’ve learned that planets orbiting stars are the rule, not the exception, which suggests that there may be 200 billion planets just in our galaxy alone, and trillions upon trillions of planets throughout the known universe. Surely, many of the planets in the Milky Way must be home to life forms, and even technologically advanced civilizations.
So where the heck are they? Why can’t we find them? Why won’t they talk to us? Would we even know it if they did? To talk about the prospects for life on other worlds, intelligent and otherwise, Point of Inquiry host Paul Fidalgo talks to journalist Lee Billings. Lee is a reporter and editor for Scientific American covering space and physics, as well as the author of Five Billion Years of Solitude: The Search for Life Among the Stars.
Billings explains how this quest, the search for extraterrestrial intelligence, has become increasingly daunting even as our knowledge of the cosmos grows richer. It is a quest rife with pitfalls, paradoxes, and plain old speculation, and so far, it has proven fruitless. But despite our apparent solitude, we keep looking. We keep listening. And we keep reaching out. Do we have the patience and the will to continue searching and waiting for a sign that may never come?
