Dr. Clément Vidal joins John Michael Godier to discuss his new paper on the Spider Stellar Engine, a hypothetical form of stellar propulsion using binary pulsar systems. The conversation explores how such systems could serve as **technosignatures**, the philosophy of post-biological civilizations, and the potential for advanced beings to manipulate entire stars or even create new universes.
