An existential PhD student hunting dark matter, a disillusioned illusionist, a medium with a secret and a murdered mathematician star in the greatest unsolved mystery of the universe. Following their acclaimed and award-winning Her Green Hell and Sisters Three, TheatreGoose presents AETHER, a show about the unknown and our insatiable desire to define it, asking why are we so desperate to know what happens behind the curtain and who gets to decide what lurks there? Part-science lab on the cusp of discovery, part-Victorian seance, part-unauthorised Nobel Prize Ceremony, AETHER explores faith, physics and magic in rich theatrical spectacle.
