Superintelligent Aliens May Ignore Humanity Just as We Ignore Ants

Astrophysicist Sara Seager reframes the Fermi Paradox, suggesting advanced civilizations might not contact us for the same reason we don't talk to ants. We are simply not interesting enough to warrant their attention or energy, even if they are studying us from a distance.

In Exoplanet Science, AI Is an Efficiency Tool, Not Yet a Discovery Engine

Contrary to popular belief, AI’s primary contribution to exoplanet research is not making novel discoveries. AI is mainly used for supervised learning to perform existing human tasks more quickly and uniformly, rather than uncovering new methods or insights humans couldn't.

Embracing Cosmic Insignificance Can Be a Comforting Antidote to Life's Tragedies

Astrophysicist Sara Seager finds comfort, not despair, in humanity's smallness. She uses the vastness of the universe as a mental tool for self-distancing. Confronting our own tragedies against a cosmic scale makes personal problems feel smaller and more manageable.

Any Alien Civilization Posing a Threat Can Already Detect Us via Our Atmosphere

The debate over broadcasting messages to aliens is moot. Astrophysicist Sara Seager argues any civilization capable of interstellar travel would first detect the oxygen in our atmosphere—a highly reactive gas that signals life—making our attempts at hiding irrelevant.

Biologists Reject Statistical Arguments for Alien Life Because We Don't Understand Life's Origin

While the sheer number of exoplanets suggests alien life is probable, astrophysicist Sara Seager explains why biologists are skeptical. Since we don't understand the mechanism of how life originated on Earth, we cannot accurately assess the probability of it occurring elsewhere.
