Results Of Ten Tears Of UCLA SETI Searches With The Green Bank Telescope
We have been conducting a search for narrowband radio signals with the L-band receiver (1.15-1.73 GHz) of the 100 m diameter Green Bank Telescope (Margot et al., 2023). So far, […]

The Catastrophic Consequences of Agnosticism for Life Searches and a Possible Workaroun
Planned and ongoing searches for life, both biological and technological, confront an epistemic barrier concerning false positives – namely, that we don’t know what we don’t know.
