Episode notes

Mass spectrometry analysis could potentially reveal evidence of alien intelligence based on the molecular weight range and number of bands observed. The focus on small biomarkers and earth chemistry bias has limited the search for extraterrestrial life, but the assembly theory suggests that complexity and abundance, free from earth biology bias, can serve as evidence of selection for universal life. This approach could revolutionize the search for alien life by enabling the detection of complexity without preconceived notions of earth-based life forms.
