Some burning questions: How do you build a machine to test Einstein's Theories? Will you need a screwdriver?

In 1985 a clueless but educable filmmaker pursues these questions, skips 3 decades, then picks the story up again, 39 years later. COSMIC CODA tells the story—as it happens—of one of the most important discoveries in physics. Much has changed in the world of astrophysics: more remarkably much has not. Scientists turn out to be human beings after all!
