Through the ages, it’s been a common trope that folks look to the stars when in search of answers about their love life. It’s really the ultimate act of human hubris, assuming the cosmos are invested in our personal lives. Constellations, the hit play from British playwright Nick Payne, tinkers with this concept in ways that make for sophisticated yet heartwarming drama. The widely lauded play made its way from London to Broadway in 2015 and features only two characters. In an exploration of love and astrophysics, especially the concept of parallel universes, the play enlivens the mind and stirs the heart in equal measure. It turns out that we, and by extension our relationships, are as infinite (and complicated) as the universe itself. Molly Cox directs Jeff Jeffers and Kate Glasheen in The Playhouse’s production.
