New study examines how extraterrestrial civilizations could become 'stellivores'

Summary

Nutrition label

88% Informative

Researchers examine what Earth 's level of technological development (aka "technosphere") will look like in the future.

They offer a reinterpretation of the Kardashev Scale, which suggests civilizations expand to harness greater levels of energy.

This is in keeping with observations of humanity's own "technosignatures," which refers to the human-made infrastructure, machinery, communications.

The Kardashev scale is the uppermost limit for a civilization's energy use, but a limit that may never actually be achieved due to thermodynamic efficiency limits.

The scenario Haqq-Misra and his colleagues proposed presents some new and interesting possibilities for advanced civilizations.

Future SETI surveys should examine "accreting binaries," closely orbiting binary stars.
