When characters in TV and movies put their spaceship into warp speed, moonwalk across a foreign planet, or scrawl some equations on a blackboard, that is the work of a science consultant behind the scenes making things look and sound as accurate as possible.
Erin Macdonald has a PhD in astrophysics, and for the past five years Erin has been the official science consultant for the Star Trek universe.
She's even earned the epithet "the Julia Child of science".
She joins Emile Donovan to share how she got into science consulting, and where she draws the line between making fiction entertaining, and making it grounded in scientific reality.
