Directed High-Intensity Beams: Reconsidering Detectability and Broadening SETI Searches

To the point

Benjamin Zuckerman argues that advanced civilizations could signal with focused, high‑power beams instead of faint, isotropic broadcasts, so detection depends on Earth being in the beam rather than the total power, suggesting we should widen searches across wavelengths and target nearby stars.

The latest research suggests that communicative civilizations would prioritize efficiency through laser-like directional broadcasting.
