Putting this interview with Andy Weir here for future reference. We’re going to see Project Hail Mary next week, and it claims the book and film are ‘built on solid science’.
But it’s described as:
a story about humanity’s last-ditch attempt to save Earth from “astrophage,” a fictional, star-eating algae that has infected our sun.
I also watched the trailer last night, and it seemed incoherent (though trailers often do).
But algae? Biology in a star, in plasma at impossible temperatures? I can feel my inner physicist cringing already, so I hope they manage to make it make sense somehow.
